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. Identify the quantities: Read the problem carefully and identify the numbers, units, relationships, or representations provided.
  2. Apply the math skill: The sum is 28, and 28 divided by 4 values equals 7.
  3. Check the result: Review the operation, estimate, units, and relationship to confirm that the answer is reasonable.

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

2. QuestionMultiple choice

What is the median of 3, 9, 4, 7, and 6?

Please select an answer first.

Correct answer: B

The correct answer is 6.

  1. Identify the quantities: Read the problem carefully and identify the numbers, units, relationships, or representations provided.
  2. Apply the math skill: Order the values as 3, 4, 6, 7, 9. The middle value is 6.
  3. Check the result: Review the operation, estimate, units, and relationship to confirm that the answer is reasonable.

Order the values as 3, 4, 6, 7, 9. The middle value is 6.

3. QuestionMultiple choice

A bag has 3 red, 2 blue, and 5 green marbles. What is the probability of choosing a blue marble?

Please select an answer first.

Correct answer: C

The correct answer is rac15rac{1}{5}.

  1. Identify the quantities: Read the problem carefully and identify the numbers, units, relationships, or representations provided.
  2. Apply the math skill: There are 2 blue marbles out of 10 total, and 2/10 simplifies to 1/5.
  3. Check the result: Review the operation, estimate, units, and relationship to confirm that the answer is reasonable.

There are 2 blue marbles out of 10 total, and 2/10 simplifies to 1/5.

4. QuestionMultiple choice

A scatter plot shows that as study time increases, test scores generally increase. What relationship is shown?

Please select an answer first.

Correct answer: D

The correct answer is A positive association.

  1. Identify the quantities: Read the problem carefully and identify the numbers, units, relationships, or representations provided.
  2. Apply the math skill: Both variables tend to increase together, which is a positive association.
  3. Check the result: Review the operation, estimate, units, and relationship to confirm that the answer is reasonable.

Both variables tend to increase together, which is a positive association.

5. QuestionMultiple choice

A survey asks 40 students and 30 choose reading as a favorite activity. What percent chose reading?

Please select an answer first.

Correct answer: A

The correct answer is 75 percent.

  1. Identify the quantities: Read the problem carefully and identify the numbers, units, relationships, or representations provided.
  2. Apply the math skill: Thirty out of 40 is 30/40, or 0.75, which equals 75 percent.
  3. Check the result: Review the operation, estimate, units, and relationship to confirm that the answer is reasonable.

Thirty out of 40 is 30/40, or 0.75, which equals 75 percent.

6. QuestionMultiple choice

Which graph is best for showing how a temperature changes over several hours?

Please select an answer first.

Correct answer: B

The correct answer is A line graph.

  1. Identify the quantities: Read the problem carefully and identify the numbers, units, relationships, or representations provided.
  2. Apply the math skill: A line graph shows change and trends across ordered time values.
  3. Check the result: Review the operation, estimate, units, and relationship to confirm that the answer is reasonable.

A line graph shows change and trends across ordered time values.

7. QuestionMultiple choice

A data set has values 5, 6, 6, 8, and 20. Which measure is most affected by the value 20?

Please select an answer first.

Correct answer: C

The correct answer is The mean.

  1. Identify the quantities: Read the problem carefully and identify the numbers, units, relationships, or representations provided.
  2. Apply the math skill: The mean uses every value, so an unusually large value changes it substantially.
  3. Check the result: Review the operation, estimate, units, and relationship to confirm that the answer is reasonable.

The mean uses every value, so an unusually large value changes it substantially.

8. QuestionMultiple choice

A spinner has 4 equal sections labeled A, B, C, and D. What is the probability of landing on A?

Please select an answer first.

Correct answer: D

The correct answer is rac14rac{1}{4}.

  1. Identify the quantities: Read the problem carefully and identify the numbers, units, relationships, or representations provided.
  2. Apply the math skill: One of four equally likely sections is A, so the probability is 1/4.
  3. Check the result: Review the operation, estimate, units, and relationship to confirm that the answer is reasonable.

One of four equally likely sections is A, so the probability is 1/4.

9. QuestionMultiple choice

A table records 12, 15, 18, and 21 visitors on four days. What is the range?

Please select an answer first.

Correct answer: A

The correct answer is 9.

  1. Identify the quantities: Read the problem carefully and identify the numbers, units, relationships, or representations provided.
  2. Apply the math skill: Range equals the greatest value minus the least value: 21 minus 12 equals 9.
  3. Check the result: Review the operation, estimate, units, and relationship to confirm that the answer is reasonable.

Range equals the greatest value minus the least value: 21 minus 12 equals 9.

10. QuestionMultiple choice

A sample of 50 trees contains 12 spruce trees. Which estimate is reasonable for the proportion of spruce trees?
