Option d
Step-by-step explanation:
We need 2 fundamental data to solve this problem.
1.- Average number of clients attended in 1 hour.
2.- Time in which it is expected that a client will be attended.
They tell us that the average number of clients served in an hour is m = 8
They tell us to calculate the probability that the client will be seen in less than 15 minutes.

Answer:
The change in the depth of water per minute
Step-by-step explanation:
We are given a graph that shows the depth of water in a bathtub as water drains out
Slope is the rate of change
We can see in the graph that on increasing the value x , the value of y decreases .
x axis represents the minutes
y axis represents the depth of water(inches)
So, On increasing minutes , the depth of water decreases
So, there is a change in depth of water per minute
So, Option D is correct
The change in the depth of water per minute
