How many ways can an irs auditor select 5 of 12 tax returns for an audit?

  792

Step-by-step explanation:

The number of ways that k things can be chosen from a collection of n things is given by ...

  nCk = n!/(k!(n-k)!)

Here, we want the number of ways 5 items can be chosen from 12. That is ...

  12C5 = 12!/(5!·7!) = 12·11·10·9·8/(5·4·3·2·1) = 11·9·8

  12C5 = 792

There are 792 ways 5 returns can be chosen from 12.

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
