Question

1.

William has the following data:
J, 14, 7, 16, 16
If the mean is 12, which number could j be?

Answer 1

7

Explanation:

The mean is the average of the numbers. Add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

7 + 14 + 7 + 16 + 16 = 60

60 / 5 = 12
