Answer:
a) For this case we define the random variable as X ="waiting time during peak hours" and we know that this distribution follows an uniform distribution:

Where a and b represent the limits of the distribution.
b) 
And the height for this case would be 0.125
Step-by-step explanation:
Part a
For this case we define the random variable as X ="waiting time during peak hours" and we know that this distribution follows an uniform distribution:

Where a and b represent the limits of the distribution.
Part b
For this case the density function would be given by:

And the height for this case would be 0.125
And
for other case.
The cumulative distribution function would be given by:



If the following shape is 90 degrees it should be consider a right triangle
Answer:
13
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
3x + y = 4
y = -3x + 4
the perpendicular slope is the reciprocal of the original slope.
so the slope would be 1/3
