Answer:
hi
Step-by-step explanation:
Y=Mx+b
Rise / run between any two points = slope (m)
Where the line crosses the y axis is (yint) (b)
Slope is -1/2
Yint = -8
So the equation is y=(-1/2)x - 8
The mean because the data is symmetrical and there are no outliers
Answer:
0.525
Step-by-step explanation:
52.5 * 0.01 = 0.525
For this case we have the following equation:

Let
