Answer:
MAD = 0
Step-by-step explanation:
When I calculated this by hand I got 0. To find the MAD:
1. You first need to find the mean of the numbers.
4 + 5 + 8 + 8 + 10 = 35
35/5 = 7
the mean value = 7
2. Then you must find the absolute value of the difference between each data value and the mean: |data value – mean|
(4 - 7) = -3
(5 - 7) = -2
(8 - 7) = 1
(8 - 7) = 1
(10 - 7) = 3
3. Add the difference values up
(-3) + (-2) + 1 + 1 +3 = 0
4. Divide the sum of the absolute values of the differences by the number of data values.
0/5 = 0
Sorry in order to answer this I need the picture of the 4 triangles
Answer:
Letty has 75%
Step-by-step explanation:
15/20 is the same as 75/100 ( 15/20·5) so she has a 75% grade
Answer:
y = 17x +128
Step-by-step explanation:
P1(-8,-8)
P2(-7,9)
Slope,
m = (y2-y1)/(x2-x1) = (9-(-8))/(-8-(-7)) = 17/(-1) = 17
The point-slope equation is
y-y1 = m(x+x1)
y-(-8) = 17(x-(-8))
y+8 = 17x + 136
y = 17x +128
