This is the question I have I need help Mr. Grill is draining his pool. The pump he is using changes the water level by -2 1/4 inches per hour. A stronger pump would drain the pool 2 1/2 times as fast. what would the change in the water level be per hour if Mr. Grill used the stronger pump?

please help me

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

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 %
