Question in picture solve

f(5) = 17

Step-by-step explanation:

substitute x with 5

f(x) = 5x - 8

f(5) = 5(5) - 8

f(5) - 25 - 8

f(5) = 17

three-fourths of an hour

36÷48=0.75

0.75=

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 %
