Respuesta :

the mean is -4 cause u have to add ale the numbers togeter

To find the mean of a set of numbers the first thing you do is add all of the numbers together.

7 + (-9) + 6 + (-10) + (-13) + (-5) = -24

After that, you divide the answer you got by how many number there are. (There are 6 numbers).

-24 / 6 = -4

B.-4

Hope this helps!
