tresset_1 [31]3 years ago
8 0
The answer would be 272 because youre trying to find the decrease which is 
340x.20 because you always move the percent over two decimals. you would get 68 after multiplying it then u would subtract that number by 340.

1. There are 10 people in a math club. Three people will be chosen for the Pi Day committee. How many different ways can club me
kaheart [24]

Answer: 120

Step-by-step explanation:

From the question, we are informed that there are 10 people in a math club and that three people will be chosen for the Pi Day committee.

The number of different ways that the club members can structure the committee goes thus:

This can be solved by:

nCr = n! / r! (n - r)!

where n = 10

r = 3

= n! / r! (n - r)!

= 10! / 3! (10 - 3)!

= (10 × 9 × 8) / (3 × 2)

=120

b). 1 way to give person 47 their prize

    1 way to give person 19 their prize

    98 ways to give out the 3rd prize

    97 ways to give out the last prize

    So, P(98,2) = 98 x 97
