1. QuestionMultiple choice

What is the mean of 4, 6, 8, and 10?

Please select an answer first.

Correct answer: A

The correct answer is 7.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: The sum is 28, and 28 divided by 4 equals 7.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

The sum is 28, and 28 divided by 4 equals 7.

2. QuestionMultiple choice

What is the median of 2, 5, 8, 9, 12, and 15?

Please select an answer first.

Correct answer: B

The correct answer is 8.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: With six values, average the two middle values: 8 plus 9 divided by 2 equals 8.5.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

With six values, average the two middle values: 8 plus 9 divided by 2 equals 8.5.

3. QuestionMultiple choice

A scatter plot shows that as temperature increases, heating costs generally decrease. What association is shown?

Please select an answer first.

Correct answer: C

The correct answer is Positive association.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: One variable increases while the other decreases, which is a negative association.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

One variable increases while the other decreases, which is a negative association.

4. QuestionMultiple choice

A bag has 4 red, 3 green, and 5 blue tiles. What is the probability of selecting a blue tile?

Please select an answer first.

Correct answer: D

The correct answer is 4 over 12.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: There are 5 blue tiles out of 12 total tiles.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

There are 5 blue tiles out of 12 total tiles.

5. QuestionMultiple choice

Which sample is most likely to represent the opinions of all students in a school?

Please select an answer first.

Correct answer: A

The correct answer is A random sample selected from the complete student roster.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: A random sample from the full roster gives students a more equal chance of selection.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

A random sample from the full roster gives students a more equal chance of selection.

6. QuestionMultiple choice

A data set has values 12, 14, 16, 18, and 20. If 10 is added to every value, what happens to the mean?

Please select an answer first.

Correct answer: B

The correct answer is It increases by 10..

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
  2. Solve step by step: Adding the same constant to every value increases the mean by that constant, so it increases by 10.
  3. Check the result: Estimate, substitute the answer, compare units, or review the model to confirm that the result is reasonable.

Adding the same constant to every value increases the mean by that constant, so it increases by 10.

7. QuestionMultiple choice

If the probability of an event is 0.72, what is the probability that the event does not occur?

Please select an answer first.

Correct answer: C

The correct answer is 0.28.

  1. Understand the problem: Identify the equation, function, relationship, shape, measurement, data set, or probability situation the question asks you to find.
