9. Chelsey puts twelve colored pieces of chocolate candy in a bag. Three pieces are green,
four pieces are yellow, two pieces are purple, and three pieces are red. She draws one
piece of candy from the bag at a time and eats it.
a.
What is the probability that Chelsey will draw out three pieces of candy in this
order: red, green, yellow? (3 points)

b.
What is the probability that Chelsey will draw out three pieces of candy in this
order: green, yellow, red? (3 points)

C.
What is the probability that Chelsey will draw out three pieces of candy in this
order: yellow, red, green? (3 points)

d.
Make a conclusion about how the order in which she draws out the red, green,
and yellow pieces affects the probability. (3 points)

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

a is the best answer choice
