I know 8x3=24 then 24 plus 32 i got 32 coz I minus 56 and 24 :) but i am not sure for this

When s units is pulled from a population of N, you could use the formula:
(N)'s' / s! = N*(N-1)*(N-2)*(N-3)...(N-s+1) / s! = N! / s!*(N-s)! Which in your case translates into: 8*7*6 / 3*2*1 = 336 / 56 = 56 If you want to learn more, check out a statistics textbook. Chibster

how did the ailplane help people
This situation is a combination, since from a group of 9 people, 4 are chosen and the order in which they are chosen is not important. So we have9C4 = (9 x 8 x 7 x 6 )/(4 x 3 x 2 x 1) = 126.The following explanation will tell you why we got this result.The first person can be any one of 9.The second person can be any one of the remaining 8.The third person can be any one of the remaining 7.The fourth person can be any one of the remaining 6.The number of ways to make this choice of 4 people is (9 x 8 x 7 x 6) = 3,024.This is a permutation, and that's what the question asked for when it asked ... "How many ways ... ".But not all of the groups chosen in these 3,024 ways are different groups. In fact, each differentgroup will show up 24 times, because 4 people can be arranged (4 x 3 x 2 x 1) = 24 ways.So the number of combinations, i.e. different groups of 4 people, is (3,024 / 24) = 126.
To solve this problem you must calculate the rate per person.15 people take 8 hours to make 100 items15p * 8h = 100i120ph = 100i1.2ph = i.So each item takes 1.2 person hours to complete (or 72 person minutes)If we need to make 50 items we need 1.2 * 50 person hours (or 72* 50 person minutes)We need 60 person hours.Since we have six people, each person needs to work 10 hours.

Informal groups are formed by people who have common interests. They could come together to solve problems or increase workplace morale.
It doesn't. Killing people is just a form of trying to solve predicaments between to different groups of people. By killing, you do nothing but make more problems.
There are only two possibilities... 10 groups of 2 or 5 groups of 4. Unless - you can have varying sized groups - which you didn't specify.

you solve the people's problems. You know your done when you get the medal from, usually, the person who presented you with the problem.
It was made to tell people if storms were coming , yet people thought that there was a person talking inside it . It doesnt solve your question sorry
The freedom of assembly is important because people should have the right to get together. Groups often are able to solve problems that individuals cannot.
You could help them find ways the person can compensate for the weakness. But you cannot "solve" it for the person.
bet that person up
