Answer:

I did the math, and the answer's not in there.

Step-by-step explanation:

Mean is the average of the data.

-12 + -9 + -14 + -39 + -49 + -49 + -18 + -43 = -233 / 8 = 29.125 = 29.1 is the mean

Median is the value in the middle. You have to arrange the numbers in ascending order first.

-49, -49, -43, -39, -18, -14, -12, -9

Notice, the middle valued are -39 & -18. In this case, get its average.

-39 + -18 = -57 / 2 = -28.5 is the median

Mode is the most frequent number in the data. So the answer is -49.

Range is the difference of largest number to the smallest number. (Take note that we are dealing with negative numbers.)

-9 - -49 = 40

olchik [2.2K]

Answer:

-24 + 12d = 2(d - 3) + 22

-24 + 12d = 2d - 6 + 22

-24 + 12d = 2d + 16

        12d = 2d + 40

        10d = 40
