GMAT Flashcards: Quant, Verbal & Data Insights Decisions
Build quick recall for the current GMAT with 300 original cards across Quantitative Reasoning, Verbal Reasoning, and Data Insights. The deck focuses on reusable concepts and decisions; full-length practice belongs in official or properly licensed question banks.
What the cards map
- Quant maps numeric forms, terms, rules, and formulas to their meaning, conditions, or use. Short scenarios ask for the operation, equation, or answer check that fits.
- Verbal maps passage and argument cues to purpose, scope, evidence, inference, reasoning flaws, and evaluation moves.
- Data Insights maps targets, constraints, source and display cues, metrics, and evidence states to the interpretation or decision they support. It covers Data Sufficiency, Multi-Source Reasoning, Table Analysis, Graphics Interpretation, and Two-Part Analysis.
Learning order
The mixed sequence keeps all three sections in rotation. Quant foundations come before algebra, models, and strategy checks; passage reading comes before argument evaluation; shared data literacy comes before the five Data Insights formats. Closely related prompts are spaced apart so one card does not cue the next.
Current-format boundary
This deck has no geometry lessons or formula drills, Sentence Correction, or the retired Integrated Reasoning section. It also excludes timing, scoring, test-center policy, full passages, large data sets, and response-pattern tricks.
Every card is an original compact concept or decision prompt. No official or competitor questions, answer choices, explanations, mark schemes, curriculum text, logos, or trade dress were copied or adapted. See the official GMAT exam content and Data Insights preparation guidance for the current exam boundary.

Karten in diesem Lernkartenset
Karte 1
Frage
Which numerator-and-denominator operation creates an equivalent fraction?
Antwort
Multiply or divide the numerator and denominator by the same nonzero number. The fraction's value stays unchanged.
Karte 2
Frage
What does data sufficiency ask you to determine?
Antwort
Whether the information guarantees one answer. You usually don’t need to calculate that answer.
Karte 3
Frage
How do you form a passage's main idea?
Antwort
Combine the passage's central topic with its main claim about that topic. The answer should cover the whole passage at the right level.
Karte 4
Frage
What does multiplying a decimal by 10ⁿ do when n is a positive integer?
Antwort
It moves the decimal point n places to the right. Dividing by 10ⁿ moves it n places left.
Karte 5
Frage
What makes information sufficient for a value question?
Antwort
It forces exactly one value for the target. Different values that satisfy all conditions make it insufficient.
Karte 6
Frage
How do you identify the passage's primary purpose?
Antwort
Name what the author is doing with the topic: explaining, comparing, challenging, defending, or proposing. Keep content and action together.
Karte 7
Frage
How do you find p percent of a quantity q?
Antwort
Compute (p/100) × q. Translate “of” as multiplication.
Karte 8
Frage
How can two valid cases prove insufficiency?
Antwort
Make the cases produce different answers to the question. One clean counterexample pair is enough.
Karte 9
Frage
How do you determine a paragraph's role?
Antwort
Connect the paragraph to what comes before and after it. Decide whether it introduces, supports, qualifies, contrasts, applies, or concludes the larger discussion.
Karte 10
Frage
A total of 45 is split in the ratio 2:3. What are the two parts?
Antwort
18 and 27. The five ratio units are worth 45 ÷ 5 = 9 each.
Karte 11
Frage
Why can an integer restriction change sufficiency?
Antwort
It removes noninteger possibilities. A range containing many real numbers may contain only one integer.
Karte 12
Frage
When is a product of signed factors negative?
Antwort
Provided no factor is zero, an odd number of negative factors gives a negative product, while an even number gives a positive product. If any factor is zero, the product is zero.
Karte 13
Frage
How should two data-sufficiency statements be tested initially?
Antwort
Test each statement independently against the stem. Do not carry information from one statement into the other.
Karte 14
Frage
What makes an integer greater than 1 prime?
Antwort
It has exactly two positive divisors: 1 and itself.
Karte 15
Frage
What should you do first on a detail question?
Antwort
Return to the relevant lines and read their local context. Memory tends to preserve the topic while blurring qualifications.
Karte 16
Frage
What is the divisibility rule for 2?
Antwort
The last digit must be even: 0, 2, 4, 6, or 8.
Karte 17
Frage
How do you test whether a fact is relevant?
Antwort
Connect it to the requested target. A true fact that does not narrow the target adds no decision value.
Karte 18
Frage
How far may a reading inference go beyond the text?
Antwort
Only as far as the text strongly supports. Prefer the smallest justified step and reject claims needing outside knowledge.
Karte 19
Frage
Why is prime factorization useful in GMAT arithmetic?
Antwort
It exposes divisibility, factors, greatest common factors, least common multiples, and perfect powers.
Karte 20
Frage
What must happen before quantities with different units are combined?
Antwort
First confirm that their dimensions are compatible, then convert them to a common unit. Keep the unit attached through the calculation to catch mismatches.
Karte 21
Frage
How do you apply a passage principle to a new case?
Antwort
Extract the principle's required conditions, then test whether the new case has them. Surface similarity isn't enough.
Karte 22
Frage
Which relationship connects distance, rate, and time?
Antwort
Distance = rate × time. Rearrange only after the units are compatible.
Karte 23
Frage
How do you find a least common multiple from prime factorizations?
Antwort
Take every prime that appears, using the largest exponent present.
Karte 24
Frage
How do you multiply powers with the same base?
Antwort
Add the exponents: aᵐ × aⁿ = aᵐ⁺ⁿ.
Karte 25
Frage
How is a weighted average computed?
Antwort
Divide the total weighted value by the total weight. For groups, use group size as the weight unless another weight is given.
Karte 26
Frage
What should a quick passage map record?
Antwort
Each paragraph's role and major viewpoint, plus the passage's overall direction. Record structure, not a sentence-by-sentence summary.
Karte 27
Frage
What does the principal square root symbol √x return?
Antwort
For real x ≥ 0, it is the nonnegative number whose square is x. For example, √9 = 3, not ±3.
Karte 28
Frage
When can bounds replace exact arithmetic?
Antwort
When the bounds separate the viable decisions. Stop once every value in the interval leads to the same choice.
Karte 29
Frage
How do you keep viewpoints separate?
Antwort
Attach each claim to its speaker: author, critic, researcher, or group. Track agreement, disagreement, and any later qualification.
Karte 30
Frage
How do “sum,” “product,” and “quotient” translate into algebra?
Antwort
They mean addition, multiplication, and division, respectively.
Karte 31
Frage
How do you reduce a fraction to lowest terms?
Antwort
Divide the numerator and denominator by their greatest common factor.
Karte 32
Frage
What evidence should determine the author's tone?
Antwort
Evaluative words, qualifications, and the treatment of competing views. Topic alone doesn't establish approval, concern, or skepticism.
Karte 33
Frage
When should rounding usually occur?
Antwort
At the end, unless estimation already settles the decision. Early rounding can move a result across a cutoff.
Karte 34
Frage
How do you convert a terminating decimal to a fraction?
Antwort
Write the digits over the matching power of 10, then reduce. For example, 0.375 = 375/1000 = 3/8.
Karte 35
Frage
When should you stop calculating in a sufficiency problem?
Antwort
As soon as uniqueness is proved or disproved. More arithmetic cannot change the sufficiency decision.
Karte 36
Frage
How do you spot an out-of-scope answer?
Antwort
It introduces a person, period, cause, or consequence the passage doesn't address. Being reasonable doesn't make it textually supported.
Karte 37
Frage
What is the percent-change formula?
Antwort
For original > 0, percent change = (new − original) / original × 100%. Percent change from zero is undefined; negative baselines require context-specific interpretation.
Karte 38
Frage
What makes information sufficient for a yes-or-no question?
Antwort
It forces the same yes-or-no answer in every valid case. The underlying value may still vary.
Karte 39
Frage
What preserves a ratio when its quantities are scaled?
Antwort
Multiplying or dividing both terms by the same nonzero factor preserves the ratio.
Karte 40
Frage
How do you reject a main-idea answer with the wrong scope?
Antwort
Compare it with the whole passage. A detail-only answer is too narrow; a claim extending beyond the passage is too broad.
Karte 41
Frage
Why should you track whether a variable is positive, negative, or zero?
Antwort
Sign controls valid cases and operations. Squaring can hide sign, and division requires a nonzero denominator.
Karte 42
Frage
How do you simplify subtraction of a negative number?
Antwort
Change it to addition: a − (−b) = a + b.
Karte 43
Frage
Whose purpose matters in a primary-purpose question?
Antwort
The passage author's purpose. A theory or researcher may be described at length without representing what the author ultimately wants to do.
Karte 44
Frage
When is the on-screen calculator most useful?
Antwort
For tedious arithmetic after the setup is clear. It does not replace choosing the right relationship or denominator.
Karte 45
Frage
In Data Sufficiency, what stem information applies when testing either statement?
Antwort
Everything in the question stem. Stem facts remain active for each statement and for the combination.
Karte 46
Frage
What is the divisibility rule for 3?
Antwort
The sum of the digits must be divisible by 3.
Karte 47
Frage
What does a transition paragraph often do?
Antwort
It closes one line of thought and sets up the next. Its role depends on both sides, not only on its first sentence.
Karte 48
Frage
When is a proxy measure useful?
Antwort
When evidence shows it reliably tracks the target for the intended decision. Correlation may support prediction, but it proves neither causation nor suitability on its own.
Karte 49
Frage
How do you find a greatest common factor from prime factorizations?
Antwort
Take each shared prime to the smaller exponent.
Karte 50
Frage
What is the arithmetic mean?
Antwort
The sum of the values divided by the number of values.
Karte 51
Frage
What units should a rate have?
Antwort
One quantity per another, such as kilometers per hour. The denominator tells you what the rate is measured against.
Karte 52
Frage
How do you divide powers with the same nonzero base?
Antwort
Subtract the exponents: aᵐ ÷ aⁿ = aᵐ⁻ⁿ.
Karte 53
Frage
What makes a paraphrase faithful to a passage detail?
Antwort
It preserves the original meaning, scope, and certainty in different words. Shared keywords alone don't make it accurate.
Karte 54
Frage
How do you recover a total from an average?
Antwort
Total = average × number of values.
Karte 55
Frage
How do you choose between two plausible reading inferences?
Antwort
Choose the one with the tighter textual chain and fewer assumptions. Plausibility in the real world is secondary.
Karte 56
Frage
What quick check can catch a calculator-entry error?
Antwort
Estimate the order of magnitude and direction first. An exact result far outside that range deserves another look.
Karte 57
Frage
How do you simplify a square root with a perfect-square factor?
Antwort
Factor out the perfect square. For example, √72 = √(36 × 2) = 6√2.
Karte 58
Frage
What makes a new example parallel to one in the passage?
Antwort
The same logical relationship. Match cause, contrast, exception, or function rather than shared subject matter.
Karte 59
Frage
When can work rates be added?
Antwort
Add the stated constant rates when the workers operate simultaneously without interfering with one another. At 1/4 and 1/6 job per hour, together they complete 5/12 job per hour.
Karte 60
Frage
What is the denominator in a percent comparison?
Antwort
The stated reference value. “A as a percent of B” means A divided by B, then multiplied by 100.
Karte 61
Frage
How do you translate “5 less than x”?
Antwort
x − 5. The phrase “less than” reverses the spoken order.
Karte 62
Frage
In Data Sufficiency, what should you check before testing values?
Antwort
The full domain. Honor stated restrictions and implicit ones such as positive lengths or nonzero divisors before judging sufficiency.
Karte 63
Frage
How do you add fractions with different denominators?
Antwort
Rewrite them with a common denominator, then add the numerators. For example, 2/3 + 1/4 = 8/12 + 3/12 = 11/12.
Karte 64
Frage
How do you distinguish description from argument in a passage?
Antwort
Description presents what happened or what a view says; argument gives reasons to accept, reject, or revise a claim.
Karte 65
Frage
How should you compare decimals with different lengths?
Antwort
Append trailing zeros and compare place by place. For example, compare 0.47 with 0.4700, which are equal.
Karte 66
Frage
How should combined statements be evaluated?
Antwort
Intersect their constraints with the stem. The combination is sufficient only if every remaining case gives one answer.
Karte 67
Frage
How do you find common ground between two viewpoints?
Antwort
Look for the narrow claim both accept, even if they disagree about its cause, importance, or implications.
Karte 68
Frage
How do you solve a proportion such as a/b = c/d?
Antwort
Cross-multiply to get ad = bc, provided b and d are nonzero.
Karte 69
Frage
How is average speed computed?
Antwort
Total distance divided by total time. It is not usually the simple mean of the segment speeds.
Karte 70
Frage
What does |x| represent?
Antwort
The nonnegative distance from x to 0 on the number line.
Karte 71
Frage
Why are strongly emotional tone descriptions often wrong?
Antwort
They overstate measured academic prose. Match the answer's intensity to the author's actual language.
Karte 72
Frage
What is the divisibility rule for 4?
Antwort
The number formed by the last two digits must be divisible by 4.
Karte 73
Frage
Can the ordinary percent-change formula be applied directly when the original value is zero or negative?
Antwort
No. The ordinary GMAT rule assumes original > 0. Change from zero is undefined, and a negative baseline requires context-specific interpretation.
Karte 74
Frage
Why can a true statement still be a wrong answer?
Antwort
It may not answer the question asked. Check the task—main idea, detail, inference, role, or purpose—before checking truth.
Karte 75
Frage
When must a weighted average lie between its component values?
Antwort
When every weight is nonnegative and the total weight is positive. The average then lies between the smallest and largest component values.
Karte 76
Frage
How do you express an integer n divided by d with remainder r?
Antwort
n = dq + r, where q is an integer and 0 ≤ r < d for positive d.
Karte 77
Frage
What does an inequality usually provide?
Antwort
A range, not a unique value. It can still be sufficient if the question asks whether a threshold is crossed.
Karte 78
Frage
How should you handle an EXCEPT detail prompt?
Antwort
Verify four statements against the passage and select the one that isn't supported. Keep the reversed task visible while checking each choice.
Karte 79
Frage
How should you set up a unit conversion?
Antwort
Multiply by a conversion factor equal to 1, placing units so the unwanted unit cancels.
Karte 80
Frage
Can two individually insufficient statements remain insufficient together?
Antwort
Yes. They may repeat the same limitation or still leave multiple valid answers.
Karte 81
Frage
For a positive base, how do you simplify a power raised to another power?
Antwort
Multiply the exponents: (aᵐ)ⁿ = a^(mn).
Karte 82
Frage
When can you infer that an author accepts a claim?
Antwort
When the author endorses it directly or relies on it without distancing language. Merely reporting another person's view isn't endorsement.
Karte 83
Frage
How should successive percentage changes be combined?
Antwort
Multiply their factors. A 10% rise followed by a 10% fall gives 1.10 × 0.90 = 0.99, a 1% net fall.
Karte 84
Frage
What are compatible numbers in estimation?
Antwort
Nearby numbers chosen to make mental arithmetic easy, such as 203 ÷ 9.9 ≈ 200 ÷ 10 = 20.
Karte 85
Frage
Which constraints are easy to overlook in a word problem?
Antwort
Countability, positivity, distinctness, and capacity limits. Translate each noun and rule into a usable constraint.
Karte 86
Frage
How do you state the exact disagreement between two viewpoints?
Antwort
Identify one claim that one side accepts and the other rejects. Don't substitute a topic that only one side discusses.
Karte 87
Frage
How do you represent three consecutive integers?
Antwort
n, n + 1, and n + 2 for an integer n.
Karte 88
Frage
How do percentage points differ from percent change?
Antwort
Percentage points are the direct difference between percentages. Moving from 20% to 25% is 5 points and a 25% relative increase.
Karte 89
Frage
What is a reversed-relationship trap?
Antwort
It swaps cause and effect, support and conclusion, or the positions of two viewpoints while reusing familiar passage language.
Karte 90
Frage
How do you multiply two fractions?
Antwort
Multiply numerator by numerator and denominator by denominator, canceling common factors when convenient.
Karte 91
Frage
How do direct and inverse proportion differ?
Antwort
Direct:
y = kx; inverse:y = k/xforx ≠ 0.Karte 92
Frage
How do you recover an original value after a percentage increase?
Antwort
Divide the new value by the growth factor. After a 20% increase, original = new ÷ 1.20.
Karte 93
Frage
When should absolute wording raise suspicion?
Antwort
When the passage is qualified. Words such as always, never, entirely, and impossible require equally strong textual support.
Karte 94
Frage
What should you identify first in Data Sufficiency?
Antwort
The exact target and answer type. Decide whether the stem asks for a value, a comparison, or a yes-or-no result.
Karte 95
Frage
What ending makes an integer divisible by 5 or by 10?
Antwort
A last digit of 0 or 5 gives divisibility by 5; a last digit of 0 gives divisibility by 10.
Karte 96
Frage
How should a Data Sufficiency condition be handled?
Antwort
Translate it into a precise constraint before testing sufficiency. Keep it separate from the conclusion you want.
Karte 97
Frage
How do you reject a half-right answer?
Antwort
Test every part of it. One accurate clause can't rescue a second clause that distorts the passage or exceeds its scope.
Karte 98
Frage
When you convert a positive measurement to a smaller linear unit, what happens to its numerical value?
Antwort
It increases. Multiply by the number of smaller units in one larger unit.
Karte 99
Frage
DS example: Is x > 5? Statement: x > 3. Is the statement sufficient?
Antwort
No. Both x = 4 and x = 6 satisfy the statement, but they answer the stem differently.
Karte 100
Frage
What is a⁰ when a is nonzero?
Antwort
- The nonzero-base condition matters because 0⁰ is not assigned this rule.
Karte 101
Frage
Which claim is the argument trying to establish?
Antwort
The main conclusion. Find the claim supported by the other statements, then check that it answers the argument's central issue.
Karte 102
Frage
When should the two statements be combined?
Antwort
When neither statement is sufficient alone. Use both constraints at once and test the remaining possibilities.
Karte 103
Frage
A positive number rounds to 8.2 to the nearest tenth. What interval contains it?
Antwort
8.15 ≤ x < 8.25. The lower endpoint rounds up to 8.2; the upper endpoint rounds to 8.3.
Karte 104
Frage
What should you check when the conclusion changes populations?
Antwort
Whether the evidence applies to the new population. Results from volunteers, specialists, or one age group may not transfer to everyone.
Karte 105
Frage
How should test values be chosen in Data Sufficiency?
Antwort
Choose valid values that probe boundaries, signs, and distinct outcomes. Random easy values can miss the deciding case.
Karte 106
Frage
How do you translate “A is 30% more than B”?
Antwort
A = 1.30B. The percentage is based on B.
Karte 107
Frage
When can one equation involving two variables be sufficient for a target?
Antwort
When every valid solution gives the same target value, even if neither variable is unique. For example, x + y = 10 is sufficient to determine x + y.
Karte 108
Frage
What does a correlation establish by itself?
Antwort
Only that two things vary together. It doesn't establish which one causes the other or whether a third factor causes both.
Karte 109
Frage
How do you divide by a nonzero fraction?
Antwort
Multiply by its reciprocal. For example, 3/5 ÷ 2/7 = 3/5 × 7/2.
Karte 110
Frage
Why is a ratio often insufficient for an absolute value?
Antwort
A ratio fixes relative size but usually leaves the scale free. Many proportional pairs can share the same ratio.
Karte 111
Frage
What is the divisibility rule for 9?
Antwort
The sum of the digits must be divisible by 9.
Karte 112
Frage
What matters most when applying a sample result to a population?
Antwort
Representativeness. The sample must resemble the target population on traits that could affect the result.
Karte 113
Frage
What should you check after solving a squared equation?
Antwort
Check every allowed root. If positive and negative roots produce different target answers, the information is insufficient.
Karte 114
Frage
What does a negative exponent mean?
Antwort
It takes the reciprocal: a⁻ⁿ = 1/aⁿ for nonzero a.
Karte 115
Frage
Which baseline makes a comparison informative?
Antwort
The baseline relevant to the claim. Compare the outcome with what would otherwise have happened, not merely with an unrelated earlier figure.
Karte 116
Frage
What risk appears when an equation factors into multiple branches?
Antwort
Each branch may create valid cases. Test all branches against the stem before deciding sufficiency.
Karte 117
Frage
How can you compare two positive fractions quickly?
Antwort
Compare their cross-products. For a/b and c/d with positive denominators, compare ad with bc.
Karte 118
Frage
What may be assumed from a Data Sufficiency diagram?
Antwort
Only marked or stated facts. Do not infer scale, equality, perpendicularity, or midpoint status from appearance.
Karte 119
Frage
What multiplier represents a p percent increase or decrease?
Antwort
Use 1 + p/100 for an increase and 1 − p/100 for a decrease.
Karte 120
Frage
Which statements count as evidence?
Antwort
The statements offered as reasons to accept another claim. Evidence may be factual or assumed for the argument, even if it isn't proven in real life.
Karte 121
Frage
Can a mean determine an individual observation?
Antwort
Not by itself. A mean fixes the total, but different sets can have that total unless more constraints apply.
Karte 122
Frage
What weakens a move from past evidence to a present claim?
Antwort
A relevant change over time. New technology, prices, rules, or behavior can make the earlier evidence a poor guide.
Karte 123
Frage
A value becomes 96 after a 20% increase. What was the original value?
Antwort
- Divide the final value by the growth multiplier: 96 ÷ 1.2 = 80.
Karte 124
Frage
How do extreme valid cases help in Data Sufficiency?
Antwort
They expose whether the target can change. Test the smallest, largest, or boundary cases allowed by the conditions.
Karte 125
Frage
How do you test for reverse causation?
Antwort
Ask whether the alleged effect could instead cause the alleged cause. Productive teams may meet more because they are productive, not the reverse.
Karte 126
Frage
Must a sufficient statement make every variable unique?
Antwort
No. It only needs to make the requested target unique, even if other variables remain undetermined.
Karte 127
Frage
A price rises 20% and then falls 20%. Does it return to its original value?
Antwort
No. The multipliers give 1.20 × 0.80 = 0.96, so the final price is 4% below the original.
Karte 128
Frage
Why can a voluntary survey be biased?
Antwort
People who choose to respond may differ from those who don't. Strong opinions or extra interest can distort the sample.
Karte 129
Frage
How do you expand a(b + c)?
Antwort
ab + ac. The outside factor multiplies every term inside the parentheses.
Karte 130
Frage
What should the final Data Sufficiency decision describe?
Antwort
Which information set guarantees an answer. It should not report the target’s numerical value.
Karte 131
Frage
What is the goal when solving a linear equation?
Antwort
Isolate the variable by applying equivalent operations to both sides.
Karte 132
Frage
DS example: Is integer n even? Statement: n = 7. Is the statement sufficient?
Antwort
Yes. It guarantees one answer—no. A statement can be sufficient even when that answer is negative.
Karte 133
Frage
When must an inequality sign reverse?
Antwort
When both sides are multiplied or divided by a negative number.
Karte 134
Frage
What must be checked before comparing two groups?
Antwort
Whether they differ in other relevant ways. Age, experience, starting level, or incentives may explain the outcome instead.
Karte 135
Frage
When is substitution preferable to elimination in a two-equation system?
Antwort
Use substitution when one variable is already isolated or easy to isolate; use elimination when coefficients cancel easily.
Karte 136
Frage
What should you build before analyzing Multi-Source Reasoning material?
Antwort
A quick source map. Note what each tab or document contains, who produced it, and the relevant date or scope.
Karte 137
Frage
How do you separate background from evidence?
Antwort
Ask whether the statement supports a claim. Background sets context; evidence does logical work in moving the argument toward a conclusion.
Karte 138
Frage
Which algebraic terms can be combined?
Antwort
Terms with the same variable part and exponents. For example, 3x² and −5x² combine, but 3x² and 3x do not.
Karte 139
Frage
When should you read the Multi-Source Reasoning question?
Antwort
Before a deep read of every source. The question tells you which details deserve attention.
Karte 140
Frage
What is a reliable first step for an equation containing several fractions?
Antwort
Multiply every term by the least common denominator, then solve the simpler equation.
Karte 141
Frage
Why does source provenance matter?
Antwort
It defines what a claim can support. An internal forecast and an audited result do not carry the same evidentiary weight.
Karte 142
Frage
What should you test when evidence comes from a different setting?
Antwort
Whether the settings differ in a way that affects the result. A finding from one market, school, or climate may not carry over unchanged.
Karte 143
Frage
What does an “and” compound inequality require?
Antwort
The overlap of both solution sets. A value must satisfy both conditions.
Karte 144
Frage
What should you compare before combining claims from two sources?
Antwort
Their population, period, units, and definitions. Matching labels can hide different scopes.
Karte 145
Frage
How can a third factor undermine a causal claim?
Antwort
It may explain both events, so their correlation no longer establishes a direct causal link by itself. Hot weather can raise both cold-drink sales and pool attendance.
Karte 146
Frage
What do one, zero, or infinitely many solutions mean for two linear equations in two variables?
Antwort
The lines intersect once, are parallel and distinct, or are the same line, respectively.
Karte 147
Frage
How should records from separate sources be linked?
Antwort
Use a shared key with the same meaning in both sources, such as product code and month. Do not join on a vague label alone.
Karte 148
Frage
How do you factor 6x + 9?
Antwort
3(2x + 3). Pull out the greatest common factor.
Karte 149
Frage
When does nonresponse threaten a survey result?
Antwort
When nonrespondents may answer differently from respondents. A high response count doesn't fix a systematic missing group.
Karte 150
Frage
What is the first step when two sources seem inconsistent?
Antwort
Compare definitions, dates, units, and aggregation levels. Many apparent conflicts come from mismatched frames.

Mit diesem Lernkartenset kostenlos lernenFlashcards wird geöffnet, damit du mit dem Lernen beginnen kannst.
Karte 151
Frage
When can you use the zero-product property?
Antwort
After rewriting a product equal to zero. If (x − 2)(x + 5) = 0, then x = 2 or x = −5.
Karte 152
Frage
How does an inference differ from a stated fact?
Antwort
A fact appears directly in a source; an inference must follow from the sources without an extra assumption.
Karte 153
Frage
Does a higher percentage by itself prove a higher count?
Antwort
No. The underlying totals matter. Twenty percent of 1,000 is more than fifty percent of 100.
Karte 154
Frage
What does an “or” compound inequality require?
Antwort
The union of the solution sets. A value may satisfy either condition or both.
Karte 155
Frage
What does a blank or omitted value establish?
Antwort
Only that the value is not provided. It does not establish zero, no change, or failure.
Karte 156
Frage
How do you recognize an intermediate conclusion?
Antwort
It is supported by one claim and supports another. It acts as both a conclusion and a premise in the same argument.
Karte 157
Frage
What should you do before writing equations for a two-quantity word problem?
Antwort
Define each variable with its unit, then translate one independent relationship per equation.
Karte 158
Frage
Why should cross-source events be placed in time order?
Antwort
Sequence separates prior conditions from later outcomes and prevents using future information as an earlier cause.
Karte 159
Frage
When should candidate solutions be checked in the original equation?
Antwort
Always after a step that may introduce solutions, especially squaring both sides or clearing variable denominators.
Karte 160
Frage
How can switching from one measured outcome to another create a gap?
Antwort
Evidence about one metric may not support a conclusion about another. More website visits, for example, don't by themselves mean more sales.
Karte 161
Frage
What makes a source relevant to a claim?
Antwort
It supplies evidence for a required link in the claim. Related background alone is not enough.
Karte 162
Frage
How do you solve a factored polynomial inequality reliably?
Antwort
Find the zeros, split the number line into intervals, and test each interval's sign. Include a zero only when equality is allowed.
Karte 163
Frage
Does happening first prove causation?
Antwort
No. The timing may fit a causal story, but coincidence or another cause can still explain the later event.
Karte 164
Frage
How can you spot an unsupported cross-source conclusion?
Antwort
Identify the bridge between evidence and conclusion. If the sources never establish that bridge, the conclusion needs an assumption.
Karte 165
Frage
What do 0 = 0 and 0 = 5 mean after simplifying an equation?
Antwort
0 = 0 means every allowed value is a solution; 0 = 5 means there is no solution.
Karte 166
Frage
What should you verify before comparing figures from different sources?
Antwort
Common units and denominators. Convert first, then compare the same quantity on the same basis.
Karte 167
Frage
How do you interpret |x − a| < r when r is positive?
Antwort
x is within r units of a: a − r < x < a + r.
Karte 168
Frage
What can a larger sample improve?
Antwort
Precision, if the sampling method is sound. A huge biased sample can still give a confidently wrong picture of the population.
Karte 169
Frage
How should a cross-source recommendation be evaluated?
Antwort
Apply the stated decision rule to the combined evidence. Do not substitute a personal preference for the rule.
Karte 170
Frage
If a worker finishes one job in t hours, what is the worker's hourly rate?
Antwort
1/t of the job per hour.
Karte 171
Frage
What can an average hide?
Antwort
The distribution. Two groups can share an average while differing sharply in range, concentration, or the number of extreme values.
Karte 172
Frage
What should you confirm before submitting a Multi-Source Reasoning answer?
Antwort
That every required part is supported by the correct source and scope. One unsupported component can invalidate the whole decision.
Karte 173
Frage
How do you find the amount of a pure component in a mixture?
Antwort
Concentration × total mixture amount. A 30% solution with volume 20 contains 0.30 × 20 = 6 units of the component.
Karte 174
Frage
What role does a concession usually play?
Antwort
It acknowledges a point that weighs against the conclusion, then answers that point or limits its relevance. Don't mistake the conceded claim for the argument's main conclusion.
Karte 175
Frage
When can an apparent cross-source discrepancy be resolved?
Antwort
When a stated difference in scope or method explains both figures. If no bridge is given, keep the conflict open.
Karte 176
Frage
What is the two-set overlap formula?
Antwort
In A or B = in A + in B − in both. Subtract the overlap because it was counted twice.
Karte 177
Frage
What should you identify first in Table Analysis?
Antwort
The row unit, column definitions, and any notes. This establishes what one record and each value represent.
Karte 178
Frage
What is the fundamental counting principle?
Antwort
Multiply the choices at successive stages when each stage has a fixed number of available choices.
Karte 179
Frage
Why distinguish relative change from absolute change?
Antwort
Relative change is the percentage change; absolute change is the amount added or lost. A 50% rise from 2 adds 1, while a 10% rise from 1,000 adds 100.
Karte 180
Frage
How should a table filter be translated?
Antwort
Turn it into an exact inclusion rule. Apply every condition before counting or comparing rows.
Karte 181
Frage
For equally likely outcomes, what is the basic probability formula?
Antwort
Favorable outcomes divided by total possible outcomes.
Karte 182
Frage
What makes a proposed causal mechanism useful?
Antwort
It explains how the cause could produce the effect. A plausible, evidence-backed mechanism strengthens the causal link.
Karte 183
Frage
How do you find the median?
Antwort
Order the values and take the middle value; for an even count, average the two middle values.
Karte 184
Frage
How should numeric values be sorted?
Antwort
By numerical value, not digit order. For example, 12 comes after 9 in ascending order.
Karte 185
Frage
What is missed when evidence includes only successful cases?
Antwort
The failures. Studying only surviving firms can make a strategy look safer or more effective than it is.
Karte 186
Frage
Two machines have stated constant rates of 1/3 and 1/5 job per hour and operate simultaneously without interference. May their rates be added?
Antwort
Yes. The stated rates are constant and the machines do not interfere, so their combined rate is 1/3 + 1/5 = 8/15 job per hour.
Karte 187
Frage
How should a table ratio be built when filters are involved?
Antwort
Derive the numerator and denominator separately from the question, then apply each filter only where it is relevant. Do not automatically filter both quantities or default to all rows.
Karte 188
Frage
What quantity is conserved when two solutions are mixed without loss?
Antwort
The amount of the pure component. Set the sum of the starting component amounts equal to the final component amount.
Karte 189
Frage
When may table rows be added directly?
Antwort
Only when they are disjoint parts of the same measure and use compatible units. Overlapping groups would be double-counted.
Karte 190
Frage
What does n! mean for a positive integer n?
Antwort
The product of the positive integers from 1 through n.
Karte 191
Frage
Where is the argument's logical gap?
Antwort
Between the evidence and the conclusion. State what must connect them without merely repeating either side.
Karte 192
Frage
How do you find the number in neither of two sets?
Antwort
Subtract the number in the union from the total population.
Karte 193
Frage
How should rates from table groups be combined?
Antwort
Divide the total numerator by the total denominator. Weight a group rate by its group size only when that size is the rate's denominator.
Karte 194
Frage
What is wrong with moving from some cases to all cases?
Antwort
The conclusion is broader than the evidence. Evidence that some members have a trait doesn't show that every member does.
Karte 195
Frage
When should you use a permutation?
Antwort
When selecting and arranging items and order matters. The number of ordered selections of r from n distinct items is n!/(n − r)!.
Karte 196
Frage
Why does table granularity matter?
Antwort
A row-level fact may disappear or change after aggregation. Match the claim to the table’s level of detail.
Karte 197
Frage
How do you find the probability that an event does not occur?
Antwort
1 − P(event). This is often the quickest route for “at least one” questions.
Karte 198
Frage
Why does a comparable control group help test causation?
Antwort
It shows what happened without the suspected cause. If the groups differ mainly in that factor, the result is harder to explain another way.
Karte 199
Frage
How should missing table entries be treated?
Antwort
As unknown unless the notes define another meaning. Exclude or include them only as the question directs.
Karte 200
Frage
What is the mode of a data set?
Antwort
A mode is any value with the greatest frequency. Under the no-mode convention, there is no mode only when at least two distinct values all have equal frequency.
Karte 201
Frage
What makes a table comparison valid?
Antwort
The values must have compatible measures, units, periods, populations, and definitions. Normalize only validly convertible differences; reject differences in population, period, or definition that cannot be reconciled.
Karte 202
Frage
What should you check when a prediction extends a past pattern?
Antwort
Whether the conditions behind the past pattern will continue. A trend alone doesn't show that its causes will remain in place.
Karte 203
Frage
How should a drain or other undoing process enter a work-rate equation?
Antwort
As a negative rate. Add productive rates and subtract rates that reverse the work.
Karte 204
Frage
How can you avoid losing your place while scanning a table?
Antwort
Evaluate one condition at a time and mark qualifying rows mentally or on the scratchpad. Count only after the final filter.
Karte 205
Frage
Can evidence that an outcome is possible show it is likely?
Antwort
No. Possibility only shows that an outcome can occur; probability requires evidence about how likely it is.
Karte 206
Frage
What correction is needed when counting the union of three sets?
Antwort
Add the three individual counts, subtract all three pairwise overlaps, then add the triple overlap back once.
Karte 207
Frage
When does a filtered table support a decision?
Antwort
When the qualifying rows satisfy the stated rule. Keep filtering, calculation, and decision as separate steps.
Karte 208
Frage
When should you use a combination?
Antwort
When selecting items and order does not matter. The number of selections of r from n distinct items is n!/[r!(n − r)!].
Karte 209
Frage
What must support a recommendation?
Antwort
A link from the proposed action to the stated goal. The argument also needs the action to be feasible and free of costs that defeat the goal.
Karte 210
Frage
How do AND and OR change a table filter?
Antwort
AND requires every condition; OR requires at least one. Parenthesize mixed rules before scanning rows.
Karte 211
Frage
How do you find the probability that independent events both occur?
Antwort
Multiply their probabilities: P(A and B) = P(A) × P(B).
Karte 212
Frage
What can make an alphabetical sort misleading?
Antwort
Labels may contain categories or embedded numbers. Confirm whether the column is text, numeric, or chronological.
Karte 213
Frage
What kind of fact most directly strengthens an argument?
Antwort
A fact that supports the missing link between evidence and conclusion. Merely repeating a premise adds little.
Karte 214
Frage
What is the range of a data set?
Antwort
Maximum value minus minimum value.
Karte 215
Frage
What should you check at a filter cutoff?
Antwort
Whether the boundary is inclusive. “At least 40” includes 40; “more than 40” does not.
Karte 216
Frage
A train covers 150 miles in 3 hours at a constant rate. What is its rate?
Antwort
50 miles per hour. Rearrange distance = rate × time to get rate = 150 ÷ 3.
Karte 217
Frage
What is the most direct way to weaken an argument?
Antwort
Undermine a necessary assumption connecting the evidence to the conclusion. The premises can remain true while the conclusion loses support.
Karte 218
Frage
What does a tie in the sorted column imply?
Antwort
The tied rows share rank on that measure. Their display order does not create a performance difference.
Karte 219
Frage
How do you identify a useful evaluation question?
Antwort
Test whether opposite answers would push the argument in opposite directions. If both answers leave the conclusion unchanged, the question isn't useful.
Karte 220
Frage
What should you identify first in Graphics Interpretation?
Antwort
The chart type and what each visual encoding represents. Bars, lines, areas, and points support different readings.
Karte 221
Frage
How do repeated identical items affect arrangement counts?
Antwort
For n total items, divide n! by the factorial of each repeated count. Identical items do not create new arrangements when swapped.
Karte 222
Frage
What should you read before estimating a plotted value?
Antwort
Both axis labels, units, and category order. Position has meaning only after the axes are understood.
Karte 223
Frage
How do you test whether a statement is a necessary assumption?
Antwort
Negate it. If that negation seriously damages the argument, the original statement was necessary.
Karte 224
Frage
How do you find the probability that one of two mutually exclusive events occurs?
Antwort
Add their probabilities: P(A or B) = P(A) + P(B). Their overlap is zero.
Karte 225
Frage
What should you verify in a chart legend?
Antwort
Which color, shape, or line maps to each series. Similar styling can otherwise swap the groups in your interpretation.
Karte 226
Frage
What does standard deviation measure?
Antwort
How spread out values are around the mean. Greater dispersion means a larger standard deviation.
Karte 227
Frage
What standard should an inference meet?
Antwort
It must follow from the given statements, without extra assumptions. Choose the modest claim the evidence guarantees.
Karte 228
Frage
What does a segment’s share depend on?
Antwort
The correct whole. A category’s share of one region may differ from its share of the full dataset.
Karte 229
Frage
For motion along the same line, when do you add or subtract two speeds to get relative speed?
Antwort
Add the speeds for opposite directions; subtract the smaller speed from the larger for the same direction.
Karte 230
Frage
What must a paradox explanation accomplish?
Antwort
Make both surprising facts plausible at the same time. Rejecting either stated fact doesn't resolve the tension.
Karte 231
Frage
How is a segment in a stacked bar measured?
Antwort
Subtract its lower boundary from its upper boundary. The upper endpoint alone is cumulative, not the segment value.
Karte 232
Frage
Eight students average 70 and twelve students average 80. What is the combined mean?
Antwort
- The group sizes are the weights: (8 × 70 + 12 × 80) ÷ 20 = 76.
Karte 233
Frage
What is the difference between a graph’s level and its rate of change?
Antwort
Level is the plotted value; rate of change is the slope. A high line can still be falling.
Karte 234
Frage
How should you describe a statement's role in an argument?
Antwort
Describe what it does, not just what it says. It may support the conclusion, present an objection, answer that objection, or illustrate a principle.
Karte 235
Frage
What is P(A given B)?
Antwort
P(A and B) / P(B), provided P(B) > 0. Restrict the sample space to outcomes in B.
Karte 236
Frage
How should slope be compared across a graph?
Antwort
Use change in vertical value divided by change in horizontal value. Visual steepness is reliable only on the same scales.
Karte 237
Frage
A driver covers equal distances at 30 mph and 60 mph. Is the average speed 45 mph?
Antwort
No. Using 60 miles for each leg gives 120 miles in 3 hours, so the average speed is 40 mph.
Karte 238
Frage
What should you identify first when evaluating a plan?
Antwort
The plan's exact goal and success measure. A proposal can produce benefits yet still fail its stated objective.
Karte 239
Frage
What does a trend in a scatterplot establish?
Antwort
An association in the displayed data. It does not by itself establish causation or predict every individual point.
Karte 240
Frage
How can you strengthen a causal explanation?
Antwort
Rule out a credible alternative cause, support the proposed mechanism, or show the effect changes when the proposed cause changes.
Karte 241
Frage
How can an outlier affect a graphical trend?
Antwort
It can pull a summary line or average away from the main cluster. Check whether the claim concerns all points or the typical pattern.
Karte 242
Frage
Why do probabilities usually change when sampling without replacement?
Antwort
The sample space changes after each draw. Update both the favorable count and the total before multiplying conditional probabilities.
Karte 243
Frage
One value in an n-value set increases by d. How does the mean change?
Antwort
It increases by d/n because the total rises by d while the count stays fixed.
Karte 244
Frage
When does a counterexample weaken a claim?
Antwort
When the claim requires the counterexample not to exist. One genuine exception can defeat an absolute claim, but may barely affect a modest one.
Karte 245
Frage
What is the parity of the sum of two odd integers?
Antwort
Even. Each odd integer is one more than an even integer, so the two extra ones add to 2.
Karte 246
Frage
What can an aggregate graph hide?
Antwort
Differences among subgroups or periods. A stable total can coexist with large offsetting changes inside it.
Karte 247
Frage
When is interpolation reasonable on a graph?
Antwort
When the graph implies continuity between nearby points. Do not interpolate across separate categories.
Karte 248
Frage
What makes information relevant to evaluating an argument?
Antwort
It bears on the uncertain link the conclusion depends on. Interesting facts about the topic may still be logically irrelevant.
Karte 249
Frage
How precise should a value read from a graph be?
Antwort
Only as precise as the scale supports. Use a defensible interval when the mark falls between ticks.
Karte 250
Frage
Must a necessary assumption prove the conclusion?
Antwort
No. It only has to be required for the argument to work; it need not be enough to establish the conclusion on its own.
Karte 251
Frage
How do you multiply positive numbers written in scientific notation?
Antwort
Multiply the coefficients, add the powers of 10, then adjust the coefficient to be at least 1 and less than 10.
Karte 252
Frage
How should a graph-based decision be made?
Antwort
Translate the visual into values or bounds, then apply the stated rule. Do not decide from appearance alone.
Karte 253
Frage
When is backsolving from answer choices especially useful?
Antwort
When the choices are concrete values and direct algebra is slower than testing them in the original conditions.
Karte 254
Frage
How can axis scale distort a visual impression?
Antwort
Unequal intervals or a truncated baseline can magnify or compress differences. Use tick values, not apparent distance alone.
Karte 255
Frage
When should you combine two statements for an inference?
Antwort
When they share a term or relationship that creates a guaranteed consequence. Don't combine them through an unstated causal or statistical link.
Karte 256
Frage
When is a product of integers odd?
Antwort
Only when every factor is odd. One even factor makes the entire product even.
Karte 257
Frage
What often resolves two apparently conflicting results?
Antwort
A hidden difference in group, time, measurement, or conditions. The results may describe different slices of the situation.
Karte 258
Frage
How should equal distances on a logarithmic axis be interpreted?
Antwort
As equal multiplicative changes, not equal absolute changes. Read the labeled values before comparing gaps.
Karte 259
Frage
Why start with a middle answer choice when backsolving ordered options?
Antwort
Its result often eliminates half the choices at once when the relationship is monotonic.
Karte 260
Frage
What makes a Two-Part Analysis response complete?
Antwort
Both selections must satisfy their own column prompts under the same stem. Treat the pair as one submitted response.
Karte 261
Frage
What is an analogy doing when it supports a claim?
Antwort
It argues that because two cases share relevant features, a result or principle from one likely applies to the other.
Karte 262
Frage
How do you represent three consecutive odd integers?
Antwort
n, n + 2, and n + 4, where n is an odd integer.
Karte 263
Frage
What should you identify before solving Two-Part Analysis?
Antwort
The role of each column. One may ask for a condition while the other asks for a consequence or decision.
Karte 264
Frage
What values should you test first in a claim about an unspecified number?
Antwort
Test allowed categories that may behave differently: positive, negative, zero, fractional, and boundary values.
Karte 265
Frage
How can an unchanged bottleneck defeat a plan?
Antwort
Improving a nonlimiting step won't improve the final outcome if another constraint still controls it. Faster ordering doesn't help when production is already full.
Karte 266
Frage
How does the shared stem affect the two parts?
Antwort
Its definitions and constraints apply to both. Keep them fixed while testing each column’s requirement.
Karte 267
Frage
How do you count the positive divisors of an integer greater than 1 from its prime factorization?
Antwort
Add 1 to each prime exponent, then multiply those results.
Karte 268
Frage
In Two-Part Analysis, must the two selected entries be the same?
Antwort
In the current format, the two selected entries may be the same or different. A linkage in the stem determines whether you must reason through them jointly, not whether their values match.
Karte 269
Frage
What makes evidence for a general claim strong?
Antwort
It should be relevant and reliable and, if case-based, come from representative cases. More evidence isn't automatically better evidence.
Karte 270
Frage
How do you factor a difference of squares?
Antwort
Use x² − y² = (x − y)(x + y).
Karte 271
Frage
When should the two Two-Part Analysis selections be solved together?
Antwort
When one shared relationship constrains both. Test candidate pairs against that relationship instead of solving isolated fragments.
Karte 272
Frage
How can one counterexample evaluate a universal claim?
Antwort
One valid counterexample disproves a claim that is supposed to hold for every allowed value.
Karte 273
Frage
How does an alternative explanation weaken a conclusion?
Antwort
It shows that the evidence can be true without the proposed explanation being true. The alternative must account for the same result.
Karte 274
Frage
In Two-Part Analysis, how can one column help solve the other?
Antwort
A valid selection can narrow the remaining candidates when the parts share a constraint. Recheck the final pair in both columns.
Karte 275
Frage
How do you test whether x² + bx + c factors into integer binomials?
Antwort
Look for integers r and s with r + s = b and rs = c. If they exist, the factorization is (x + r)(x + s).
Karte 276
Frage
Which unknown should you evaluate first in a plan argument?
Antwort
A condition that could make the plan achieve or miss its goal. Focus on feasibility, response, costs, and side effects tied to that goal.
Karte 277
Frage
How should a trade-off between two measures be evaluated?
Antwort
Apply the stated priorities or limits. An option is better only relative to the rule, not because one measure is largest.
Karte 278
Frage
How can estimation screen answer choices before exact calculation?
Antwort
Approximate the expression's magnitude, then eliminate choices that are far too large or too small.
Karte 279
Frage
In a constrained-decision Two-Part Analysis problem, what should you check before comparing candidates?
Antwort
Check every hard constraint first. Discard any option that breaks a required limit, then compare only the feasible candidates.
Karte 280
Frage
What does a defensive assumption do?
Antwort
It rules out a threat that would break the argument. For example, a revenue plan may assume that its added costs won't exceed the new revenue.
Karte 281
Frage
What restriction applies when a variable appears in a denominator?
Antwort
Exclude every value that makes the denominator zero.
Karte 282
Frage
How does an objective differ from a constraint?
Antwort
A constraint determines what is allowed; an objective ranks the allowed options. Apply them in that order.
Karte 283
Frage
Which quick checks catch many Quant answer errors?
Antwort
Check the sign, units, allowed range, and rough size against the question's conditions.
Karte 284
Frage
What inference is safe from a statement about most members?
Antwort
More than half have the stated trait. You can't infer that all do, that any particular member does, or that most have another trait.
Karte 285
Frage
How should a two-part threshold rule be handled?
Antwort
Translate each threshold with the correct inequality, including its boundary. Then test both selected values against it.
Karte 286
Frage
Where can one negative sign appear in a fraction without changing its value?
Antwort
Before the fraction, in the numerator, or in the denominator: −(a/b) = (−a)/b = a/(−b), provided b ≠ 0.
Karte 287
Frage
How does an argument choose between competing explanations?
Antwort
It presents evidence that one explanation handles better than the others, often by ruling out a rival prediction.
Karte 288
Frage
What is an efficient way to handle two linked algebraic targets?
Antwort
Express both in terms of one variable or invariant. Evaluate candidate values only after the relationship is clear.
Karte 289
Frage
How do you solve x² = c over the real numbers?
Antwort
If c > 0, x = ±√c; if c = 0, x = 0; if c < 0, there is no real solution.
Karte 290
Frage
What should you check when two selected quantities form a ratio?
Antwort
Order and scale. The ratio A:B is not interchangeable with B:A, and proportional pairs may all fit.
Karte 291
Frage
How does a positive proper fraction compare with 1?
Antwort
It is less than 1 because its numerator is smaller than its denominator.
Karte 292
Frage
Which side effects matter when evaluating a plan?
Antwort
Effects that change the plan's net result or work against its goal. A small unrelated inconvenience usually doesn't matter.
Karte 293
Frage
How should a two-part logical claim be tested?
Antwort
Separate the condition from the conclusion, then test whether each selected statement performs the requested role.
Karte 294
Frage
What is the solution pattern for |x| = a over the real numbers?
Antwort
If a > 0, x = ±a; if a = 0, x = 0; if a < 0, there is no real solution.
Karte 295
Frage
What unit check belongs in a two-part quantitative answer?
Antwort
Confirm that each selection has the unit requested by its column. Linked values may require different conversions.
Karte 296
Frage
Why does user response matter to a plan?
Antwort
The plan may depend on people adopting, following, or not avoiding it. Availability alone doesn't guarantee the needed behavior.
Karte 297
Frage
A response rate rises from 40% to 50%. What are the percentage-point change and the relative percent increase?
Antwort
The increase is 10 percentage points and 25% relative to the original rate: (50 − 40) ÷ 40 = 0.25.
Karte 298
Frage
What is the final check for Two-Part Analysis?
Antwort
Read each column prompt with its chosen entry, then verify that the pair is jointly consistent with the stem.
Karte 299
Frage
For real x and y, what two linear cases are equivalent to x² = y²?
Antwort
x = y or x = −y.
Karte 300
Frage
How should benefits and costs be compared in a plan argument?
Antwort
By their net effect on the stated goal. A plan can create the intended benefit but still fail if its relevant costs are larger.
