Water coming out from a fountain is modeled by the function f(x) = -x^2 + 8x +2 where f(x) represents the height in feet of the water from the fountain at different times x in seconds
what does the average rate of change of f(x) from x=1 to x= 4 represent ? m

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 %
