Which graph below solves the following system of equations correctly?
y = three over four times x squared minus 3
y = negative three over four times x squared plus 3
a) two quadratic graphs opening up. they intersect at 0 and negative 3.
b)one quadratic graph opening up and one quadratic graph facing down. they intersect at 0, 3.
c) quadratic graph opening up and quadratic graph opening down. they intersect at 0, negative 3.
d) two parabolas one facing down with a vertex at 0, 3 and one facing up with a vertex at 0, negative 3

D) two parabolas one facing down with a vertex at 0, 3 and one facing up with a vertex at 0, negative 3

First of all, let's rewrite the equations in a mathematical language:

Since the leading coefficient, the number that accompanies is positive, that is, its value is 3/4, then the parabola opens upward. On the other hand, the vertex can be found as:

Since the leading coefficient is negative, that is, its value is -3/4, then the parabola opens downward. Similarly the vertex can be found as:

Both graph are shown below and you can see that the conclusion of our problem is correct.

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 %
