What is the best substitution to make to evaluate the integral of the product of 4 minus x and 5 raised to the 4 minus x quantity squared, dx ? here I've stated it differently(it's the same integral): integral (4-x)5^(4-x)^2 dx
Answers:
u = 4 - x
u = (4 - x)2
u = 5(4 - x)
u = -x

20

step-by-step explanation:

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 %
