1 Question 1 of 10

Not answered

Find the mean of the numbers: 4, 6, 8, 10.

Hint: Add all the numbers, then divide by how many numbers there are.

Explanation: Add the numbers: 4 + 6 + 8 + 10 = 28. There are 4 numbers, so the mean is 28 ÷ 4 = 7.

2 Question 2 of 10

Not answered

Find the median of the numbers: 3, 9, 5, 7, 1.

Hint: Put the numbers in order first, then find the middle value.

Explanation: Order the numbers: 1, 3, 5, 7, 9. The middle value is 5, so the median is 5.

3 Question 3 of 10

Not answered

Find the mode of the numbers: 2, 4, 4, 6, 8, 8, 8.

Hint: The mode is the value that appears most often.

Explanation: The number 8 appears three times, more than any other value. So the mode is 8.

4 Question 4 of 10

Not answered

Find the range of the numbers: 12, 5, 9, 20, 7.

Hint: The range is the largest value minus the smallest value.

Explanation: The largest value is 20 and the smallest value is 5. The range is 20 − 5 = 15.

5 Question 5 of 10

Not answered

A bag has 3 red balls and 2 blue balls. What is the probability of picking a red ball?

Hint: Probability = favorable outcomes / total outcomes.

Explanation: There are 3 red balls and 5 balls in total. The probability of picking a red ball is 3/5.

6 Question 6 of 10

Not answered

What is the probability of rolling a 6 on a fair six-sided die?

Hint: A fair die has 6 equally likely outcomes.

Explanation: Only one side has the number 6, and there are 6 possible outcomes. So the probability is 1/6.

7 Question 7 of 10

Not answered

The scores are 70, 80, 80, 90, 100. What is the mean score?

Hint: Add all scores and divide by 5.

Explanation: 70 + 80 + 80 + 90 + 100 = 420. Divide by 5: 420 ÷ 5 = 84.

8 Question 8 of 10

Not answered

In a class survey, 12 students chose soccer, 8 chose basketball, and 5 chose tennis. How many students were surveyed?

Hint: Add the numbers from all categories.

Explanation: Add the students: 12 + 8 + 5 = 25. So 25 students were surveyed.

9 Question 9 of 10

Not answered

If the probability of rain is 0.25, what is it as a percentage?

Hint: To convert a decimal to a percent, multiply by 100.

Explanation: 0.25 × 100 = 25. So the probability is 25%.

10 Question 10 of 10

Not answered

A spinner has 4 equal sections: red, blue, green, and yellow. What is the probability of landing on blue or green?

Hint: Count the favorable sections and divide by the total number of sections.

Explanation: There are 2 favorable sections: blue and green. There are 4 sections total. So the probability is 2/4 = 1/2.
