Answer:
0% probability that a customer will be exactly 7.50 minutes in the record store.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
The probability of finding a value between c and d is:
The probability of finding a value above x is:
The uniform distribution is a continuous distribution, which means that the probability of an exact outcome is zero.
Uniformly distributed between 3 and 12 minutes.
This means that 
What is the probability that a customer will be exactly 7.50 minutes in the record store?
Continuous distribution, so:
0% probability that a customer will be exactly 7.50 minutes in the record store.
I do believe the answer is 9
74.51 would evenly go into 5553 i think
Here, ∠1 + ∠2 = 180 [ Supplementary Angles ]
∠1 + ∠6 = 180 [ ∠2 = ∠6 ]
(corresponding angles)
123.5 + ∠1 + 180
∠1 = 56.5
In short, Your Answer would be Option A
Hope this helps!
