Question

11. On a math exam, two students scored 95, five students scored 87,

three students scored 73, four students scored 63, and one student
scored 40. What was the class average?

Answer 1

About 76%.

Explanation:

To find the average of numbers, you add all of the numbers together and divide the total by the number of numbers. In this case, your numbers would be 95 twice, 87 five times, 73 three times, 63 four times, and 40 once. The total number of numbers is 15, and the total of all of the exam scores if you add them up is 1136. Finally, you would divide 1136 by 15, which would be 75.7333333, which would be an average of about 76%.
