Question 12 options:

–16

–25

–96

16

Answer 1

Answer: FIRST OPTION.

Explanation:

To calculate the average of a set of numbers, we need to add the numbers and divide the sum by the amount of values into that set.

For example, given a set of numbers:

`a,b,c,d`

The average will be:

`average=(a+b+c+d)/(4)`

Then, the average of the given set of numbers (-25, -70, 15, -31, -25, and 40) is:

`average=(-25+(-70)+ 15+(-31)+(-25)+40)/(6)\\\\average=(-25-70+ 15-31-25+40)/(6)\\\\average=-16`

Answer 2

-16

Explanation:

The average of –25, –70, 15, –31, –25, and 40 is -16

To determine the average of the numbers given, we shall find their sum then divide this sum by the number of values;

The sum of the numbers is;

-25-70+15-31-25+40 = -96

We have a total of 6 values, thus the average becomes;

(-96)/6 = -16
