Beth wants to perform an experiment she will toss a colored chip 20 times the chip has one red side and one yellow side she wants to compare the theoretical probability of the chip landing red side up to the experimental probability of the chip landing red side up

She would have 50% of the chips be yellow side up and 50% of the chips be red side up.

Step-by-step explanation:

Hope this answered your question.

i assume you mean  3x^2 + 16y = 0

so y =  -3/16 x^2

The vertex is at the origin (0,0)  answer

x^2 = -16/3 y

compare with standard form x^2 = 4ay:-

the focus y coordinate of the  a =  -16/3  / 4

= -16/12 =  -4/3   so the focus is (0, -4/3) answer

and the directrix is y = 4/3  answer
