BD=16 and AC the
perpendicular bisector of BD.

y = 5

Step-by-step explanation:

If AC is the perpendicular bisector of BD, that would mean that y+3=2y-2.

Now it's just simple algebra.

Solving for y, you get y=5.

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 %  

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
