Answer:
Option D,
Step-by-step explanation:
<u>Step 1: Find the y-int</u>
The value of y when x is 0: 4 -> This is the b for y = mx + b
y = mx + 4
<u>Step 2: Find the slope</u>
Since the line is facing in a negative direction, that means that it is negative. Also the slope is -3.
y = -3x + 4
<u>Step 3: Find the shaded region</u>
Since the shaded region is below/before the line, that makes this inequality:

<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 .
(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 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 .
