Answer:
Mean: 78.8
M.A.D(Mean Absolute Deviation): 2.3
Step-by-step explanation:
Mean: 73, 75, 76, 78, 78, 79, 79, 80, 81, 81, 82, 84 = 946/12 = 78.8
Mean Absolute Deviation (M.A.D):
78.8 - 73 = 5.8
78.8 - 75 = 3.8
78.8 - 76 = 2.8
78.8 - 78 = 0.8
78.8 - 78 = 0.8
78.8 - 79 = 0.2
78.8 - 79 = 0.2
78.8 - 80 = 1.2
78.8 - 81 = 2.2
78.8 - 81 = 2.2
78.8 - 82 = 3.2
78.8 - 84 = 5.2
5.8 + 3.8 + 2.8 + 0.8 + 0.8 + 0.2 + 0.2 + 1.2 + 2.2 + 2.2 + 3.2 + 5.2 = 28.4/12 = 2.3

-please mark me the brainliest if i'm correct-
Hey! Your answer for this is
7x^2 + 3x^2 = 10x^2
-2x + 15x = 13x
9 - 4 = 5
Hence, 10x^2 + 13x + 5.
Hope this helps!
Answer:
Solve the equation for x.
The simplified system is the arbitrary solution of the original system of equations.
Y=x+14
y=18−x2
Reorder 18
and −x2.
y=−x2+18
Y=x+14
Solve the equation for Y.
Y=−2y+50
x=36−2y
Reorder 36
and −2y.
x=−2y+36
Y=−2y+50
Step-by-step explanation:
Answer:
Length is twice the Width
Perimeter = 126 ft.
let width = W
length = 2W
P = 2 length + 2 width
126 ft. = 2(2W) + 2W
126 ft. = 6W
21 ft. = W
width is 21ft., length is 42 ft.
