Midpoint : (x1 + x2) / 2, (y1 + y2)/2
(-17,-7)....x1 = -17 and y1 = -7
(x,y)....x2 = x and y2 = y
sub
m = (-17 + x)/2 , (-7 + y)/2

(-17 + x) / 2 = - 9
-17 + x = -9 * 2
-17 + x = -18
x = -18 + 17
x = -1

(-7 + y)/2 = -1
-7 + y = -1 * 2
-7 + y = -2
y = -2 + 7
y = 5

so ur other endpoint is (-1,5) <==

Here is the histogram of a data distribution.<br> What is the shape of this distribution?
Pavlova-9 [17]

Answer:

Unimodal-Skewed

Step-by-step explanation:

A distribution is called unimodal if it has only one hump in the histogram.

A symmetric distribution is equally divided on both sides of the highest hump.

The given histogram has only one hump at 4 and as it is not symmetrically distributed, it is skewed.

So the correct answer is:

Unimodal-Skewed ..
