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:



Answer:
We can't solve this because we can't add graphs. One way you could solve it would using Desmos.
Step-by-step explanation:
Answer:
154 is less than or equal to 5x+7y
Step-by-step explanation:
x = number of gift cards and y= number of teddy bears
Answer:
y/2 = tan(60) => y = 2 tan(60) = 2sqrt(3) = 3.464
