What is the mean of -9,-5,-4,-4,-2,0,1,2,3,5

- 1.3

Step-by-step explanation: I believe that it's -1.3 if you're referring to the arithmetic mean.

(1) Take the sum of -9, -5, -4, -4, -2, 0, 1, 2, 3, 5 and simplify it to -13

(2) Count the number of terms in the data set.

{-9, -5, -4, -4, -2, 0, 1, 2, 3, 5}

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10} - The number of terms in the data set is 10.  

(3) Divide the sum by the number of terms and simplify.

-13 / 10 = -1.3 (simplified)

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
