A group of 5 men are meeting for lunch.

Sladkaya [172]

Tile:

<h2>See the explanation.</h2>

Step-by-step explanation:

(a)

There were total 5 men wearing coats.

5 coats can be returned to 5 men in 5! = 120 ways.

The coats can be returned to the accurate persons only in 1 way.

Hence, the probability that each man gets the correct coat is $\frac{1}{120}$ .

(b)

At the time of returning the first coat, the hostess will have 5 choices and for the second she will have 4 choices.

Hence, in $5\times4 = 20$ ways the hostess can return the 2 coats.

There is only 1 possible case that each of the coats will return to the correct owner.

Hence, the required probability is $\frac{1}{20}$ .

Use the graph below to answer the question that follows:

aniked [119]

Answer:

$\boxed{-\frac{6}{\pi}}$

Step-by-step explanation:

The average rate of change over a interval is the slope m of the straight line joining the two points.

$m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }\\\\= \frac{-1 - 5}{ \pi - 0}\\\\= -\frac{ 6}{\pi }$

The average rate of change is $\boxed{-\frac{6}{\pi}}.$
