Question

Solve and explain each?

Answer 1

6+4+5+9+8+7=39 sum
39/6=6.5 mean

Answer 2

Explanation:

First, you need to know all the numbers. 4 occurs twice, 5 occurs once, 6 occurs twice, 7 doesn't occur, 8 occurs twice, and 9 occurs once. So, if you laid it out, it would look like this: 4,4,5,6,6,8,8,9.

So to find the sum, you add all of those together which will give you 50.

To find the mean, you will need to find the sum (50) and divide that by the number of values which can be shown as : 50/8 or 6 1/4.

So, the sum would be 50 and the mean would be 6 1/4.
