Answer:
Step-by-step explanation:
There are a few ways to go about doing this problem. One method would to divide the shape into two triangles and a rectangle and then find the area of those shapes and then add them all up. I am not going to do that because that is the long way to solve this problem.
<u>With that said, you can use the trapezoid formula</u>
b1 = 3
b2 = 11
h = 9
<u>Plugin the data into our model and do the math.</u>

Answer:
Incomplete question, but the concepts of the uniform distribution needed to solve this question are given here.
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 waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between a and b minutes.
From here, we get the values of a(smallest value) and b(highest value).
Question of the probabilities:
In the two probability questions, you will get the value of x, and will apply one of the three formulas given above, depending on the question, to find the desired probability.
