2x^2 – 15x + 7

(2x - 1) (x - 7).

Step-by-step explanation:

2x^2 - 15x + 7

Use the ac method:

ac = 2 * + 7 =  +14

-1 * -14 =  + 14 and -1 + -14 = -15 so we replace -15x by - x - 14x:

2x^2 - x - 14x  + 7

= x(2x - 1) - 7(2x - 1)

= (2x - 1) (x - 7)

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 %
