The choir club at a local school is running a field to a waterpark. there are 6 parks the club is considering. the director has asked the members to each pick three to narrow down the list of possibilities before making a final decision. how many different possibilities are there for the list of three? a. 20 b. 150 c. 30 d. 120

The formula , where r! is 1*2*3*...r

is the formula which gives us the total number of ways of forming groups of r objects out of n objects.

for example, given 10 objects, there are C(10,6) ways of forming groups of 6, out of the 10 objects.

Thus, there are C(6, 3) many ways of forming different triples out of 6.

A.20

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

i got 10.28 but that rounds up to 10.3
