Question

In Ms. Dole's class, students received grades of 87, 72, 99, 93, and 84 on yesterday's quiz. What was the mean of the quiz grades?

Answer 1

The mean of a set of numbers is the average of all the numbers

To find the average, or the mean, the numbers must be added together and then the sum is divided by the total amount of numbers in the set.

87 + 72 + 99 + 93 + 84 = 435
435 / 5 = 87

The mean of the quiz grades is 87

Answer 2

Hello!

The mean is the average of the numbers

To find the average you add them all up and divide the sum by the amount of numbers added

87 + 72 + 99 + 93 + 84 = 435

Divide the sum by the amount of numbers added

435 / 5 = 87

The answer is 87

Hope this helps!
