Which is the equation of a parabola with vertex (0, 0), that opens to the right and has a focal width of 8? a. y^2=8x b. y^2=-8x c. x^2=8y d. x^2=-8ywhich is the equation of a parabola with vertex (0, 0), that opens to the right and has a focal width of 8? a. y^2=8x b. y^2=-8x c. x^2=8y d. x^2=-8y

the first answer is A y^2=8x

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 %
