Explanation:
It is the average (mean) of the absolute values of the differences between a set of numbers and their mean.
Example: consider the set {1, 2, 4}. The mean is computed in the usual way: the sum divided by the number of contributors —
mean = (1 + 2 + 4)/3 = 7/3 = 2 1/3
Then the deviations are ...
1 -2 1/3 = -1 1/3 . . . . the absolute value of this is 1 1/3
2 -2 1/3 = -1/3 . . . . . the absolute value of this is 1/3
4 -2 1/3 = 1 2/3 . . . . the absolute value of this is 1 2/3
The mean of these absolute values is their sum divided by the number of them:
(1 1/3 +1/3 +1 2/3)/3 = (3 1/3)/3 = 1 1/9
The MAD of {1, 2, 4} is 1 1/9.

Your graphing calculator or spreadsheet program may have a function that will calculate this for you.
22 because i am in college and i know what i am doing
Answer:
A negative exponent means that the number will be a decimal.
so 4 X 10^-9 (-9 being the exponent of 10)
the answer to this equation would be 0.000000004 because the decimal moves 9 times to the left
The quadrants of the points are
- Quadrant 1: Points A and D
- Quadrant 2: Points E and H
- Quadrant 3: Points G and J
- Quadrant 4: Points C
- x-axis: Point F
- y-axis: Point B and I
<h3>How to determine the quadrants?</h3>
The points are given as:
A(2, 4) B(0, -3) C(1, -1)
E(-4,1) G(-3,-2) I(0, 2)
D(3, 3) F(2,0) H(-2, 3)
J(-1,-4)
Next, we plot each coordinate on a graph (see attachment)
From the attached graph, we have the following categories
Quadrant 1: Points A and D
Quadrant 2: Points E and H
Quadrant 3: Points G and J
Quadrant 4: Points C
x-axis: Point F
y-axis: Point B and I
