Answer 1

a) 21+30+10+4+19+31+7+17+4=148

148 divided by 10= 14.8

b) 148+17=165

165 divided by 11= 15

Explanation:

In math, the mean is the average of a set of numbers. To find the mean of a data set, add up all of the numbers in the set, and then divide that total by the amount of numbers in the set.
