Find the mean absolute deviation (MAD) of the data in the pictograph

1.5

Step-by-step explanation:

First, find the mean (average) of the data set.

mean = (x1 + x2 + ...)/N

where x1, x2, ... are the data points, and N the total amount of data points.

mean = (7 + 2 + 4 + 3)/4 = 4

Then, mean absolute deviation is computed as follows:

MAD = (|x1 - mean| + |x2 - mean| + ...)/N

MAD = (|7 - 4| + |2 - 4| + |4 - 4| + |3 - 4|)/4

MAD = (3 + 2 + 1)/4 = 1.5

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

its not b
