What is the Mean Absolute Deviation?

Mean Absolute Deviation (MAD) is found through the following steps

1) Find the mean. We add up the values and divide by the number of items.

2) Subtract each value from the mean and apply absolute value to ensure the result is not negative. This tells us how far each value is from the mean. Call these sets of distances set D.

3) Find the mean of set D, using the idea talked about in step 1. This will produce the MAD.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

-1/3(x+1)^5

i’m pretty sure this is correct
