Answer:
Step-by-step explanation:
The total number of students is 350 + 50 + 225 + 375 = 1000.
There are 225 students in band only, as well as 50 students in both band and choir. So there are 275 students in band out of the total of 1000, or 27.5%.
There are 350 students in choir only, as well as 50 students in both choir and band. So there are 400 students in choir, 50 of whom are also in band. So the probability is 50/400, or 12.5%.
The probabilities are not the same.
Since the probabilities are not the same, the probability of being in band is affected by whether or not the student is in choir. So the events are not independent.

Step-by-step explanation:
Given
Solving (a): What does h represents
From the instruction in the question, we understand Cycle city charges an additional 0.75 per hour.
This implies that h represents the additional hour of rentals
Solving (b): What does 15 represents
From the instruction in the question, we understand Cycle city charges an a base charge of $15
This implies that 15 represents the base charge
Solving (c): 0.75h
Referring back to (a) where h represents the additional hour of rentals
0.75h represents the total charges for the additional hour
An hour has 60 minutes so 1/40 of an hour is:
(1/40)(60) = 60/40 = 6/4 = 3/2 = 1.5
so 1/40 of an hour is a minute and a half
