Suppose that there were a strong correlation between the variables d and f.
which of these is a true statement?
o
o
a. d must not cause f.
b. fmust cause d.
o
c. d must cause f.
o
d. dmay cause f.

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,

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
