If we need to select r objects from total of n objects , then total number of ways to select r objects is given by formula :

How many ways can an irs auditor select 4 of, №16482331, 28.08.2020 18:04

Therefore, number of ways of selecting 4 tax returns for audit out of 9 tax returns :

How many ways can an irs auditor select 4 of, №16482331, 28.08.2020 18:04

Hence, Number of ways an IRS auditor can select 4 of 9 tax returns for an audit = 126

The correct option is A). 126

Step-by-step explanation:

Total number of tax returns = 9

Number of tax returns to be selected for an audit = 4

This is based on the concept of combinations which states that :

If we need to select r objects from total of n objects , then total number of ways to select r objects is given by formula :

_{r}^{n}\textrm{C}

Therefore, number of ways of selecting 4 tax returns for audit out of 9 tax returns :

=_{4}^{9}\textrm{C}\\\\=\frac{9!}{4!\times (9!-4!)}\\\\=\frac{9!}{4!\times 5!}\\\\=126

Hence, Number of ways an IRS auditor can select 4 of 9 tax returns for an audit = 126

So, the correct option is A). 126

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
