Find the average rate of change for the given function x=-1 to x=2

a. 4/3
b. -4/3
c. -3/4
d. 3/4

The Average rate of change (the slope) is -4/3

Step-by-step explanation:

Find two Exact point like point A (-1,4) and point B (2,0)

Then count how many spaces does point A have to move left to right and down to get to point B.

since it moves down the number will be negative.

You will have to go 3 spaces to the right and 4 spaces down.

therefore giving you a slope of -4/3

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
