Answer 4

Mean is the average..add all the numbers and divide by 4(the amount of numbers).

-9 + -8 + 4 + -1 = -14

What's -14 / 4? @newwar248

Answer 5

@Rosabearof10 Don't give out answers, plus your answer is wrong.

Answer 6

The mean is the average of all of the numbers.

To find the mean all you have to do is add all of the numbers together and then divide by the number of numbers you have.

So in this case you would do
\[\frac{ -9+-8+ 4+-1}{ 4}\]
