Which equation is a function of x?

x=5
x=y2+9
x2=y
x2=y2+16

Q x=y2+9

Step-by-step explanation:

x=y2+9

where x=5

5=y2+9

5/2=y+9

2.5+9=y

11.5=y

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 %

i think asking google will you get the answer to that question
