Ahigh school debate team is made up of 9 boys and 7 girls. their coach is going to choose four of them to go to a competition. 1. in how many different ways can the coach choose 3 girls and 1 boy to go? 2. what is the probability that the coach chooses 3 girls and 1 boy to go? 3. what is the probability that the coach chooses 3 boys and 1 girl to go?

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
