Question

how many 3-person groups can be formed in a club with only 8 people? Explain

Answer 1

8C3

Answer 2

or simply 8P3
----
3!

Answer 3

either way its 56

Answer 4

the explaining part is a bit sketchy; youd have to draw diagrams and lines and subtract out the things you count twice and such

Answer 5

oh okay thank you so much

Answer 6

there are a total of 8*7*6 ways to pick 3 people out of 8; 336 ways, but alot of those groups are the same since that method does not consider different groupings of the same elements to be the same.

abc and bca and cab would all be counted as different; so we have to adjust for that

Answer 7

ohhhhhhh

Answer 8

The sales tax rate in Jackson is 8% of which the town keeps all the proceeds. The town is saving for a new traffic meter which costs $124. How much must the Jackson sell to earn enough money to purchase the new traffic meter?

Answer 9

124 equals 8 percent of some value; so divide 124 by 8 to get 1 percent of the value and just multiply that by 100 to get the total amount

124
---- x 100 = total amount needed
8

Answer 10

i tried that its telling me the answer is
1148.15

Answer 11

its multiple choice and i just took the 1550 and multiplied it by .08 to get 124 then i figured that was the right answer but i got it wrong

Answer 12

1550 should be the right answer with what you have given

Answer 13

the 1148.15 had to be a result of a wrong entry ...

Answer 14

does the 8% mean that they keep all 8%? or that they keep all of the money made?

Answer 15

if they are keeping all the monies, and what they sell earns them an extra 8% then:

124 = M(1.08)

124/1.08 = M = 114.814...
