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?
10 17 12 8 9 7 15 14 6 12
add these up and divide by 10.
To find the mean (average) weight of the 10 backpacks, you need to calculate the sum of all the weights and divide it by the total number of backpacks. Here's how you can do it:
Add up all the weights: 10 + 17 + 12 + 8 + 9 + 7 + 15 + 14 + 6 + 12 = 110
Then, divide the sum by the total number of backpacks (which is 10 in this case):
110 ÷ 10 = 11
So, the mean weight of the 10 backpacks is 11 pounds.
