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 grade

Naddika [18.5K]

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!
