Answer:

B. -3.

Explanation:

A ' middle' number looks like -3.

(4 + -4 - 17 + 5) / 4

= (-21 + 9) /4

= -12/4

= -3.

Answer:

B) -3

Explanation:

The average can be found by dividing the sum of the numbers by the total number of numbers.


mean = (the \: sum)/(n)


mean = (4 + ( - 4) + ( - 17) + 5)/(4)


mean = (0 + ( - 12))/(4)


mean = ( - 12)/(4)


mean = - 3

The mean is -3, so we can say the answer is B.
