Answer 1

43.75, or 43.8 to the nearest 10th

Explanation:

The mean is the mathematical average of a set of two or more numbers. Summing the numbers in a set and dividing by the total number gives you the arithmetic mean.

The total of your numbers is 700.

There are 16 numbers.

700 divided by 16 is 43.75
