Answer:
y ≤ 3
y ≥ 1
y ≥ -2x + 2
Step-by-step explanation:
the two horizontal lines are y ≤ 3 and y ≥ 1
the intersecting line has a slope of -2 and a y-intercept of 2
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.

Step-by-step explanation:
Answer:
100°
Step-by-step explanation:
55°+25°+third angle=180°(by angle sum property)
80°+third angle=180°
third angle=180°-80°
third angle=100°
Is it a right triangle ?!
