Question

Anna did a survey on the weight of students' backpacks at her middle school. The weights, in

pounds of 10 backpacks are listed below. What is the mean (average) weight, in pounds, of the
10 backpacks?
12, 5, 8, 6, 15, 11, 13, 10, 13, 7

Answer 1

A:10

Explanation:

Add up all the weight of the backpacks-

12+5+8+6+15+11+13+10+13+7
which gives you 100.

Then divide the total weight by the number of backpacks which in this case is 10-

100/10
which means the average weight is 10.
