Answer:
y = 10
Step-by-step explanation:
-7x + 3y = 30
(-7 x 0) + 3y = 30
0 + 3y = 30
3y = 30
y = 10
Answer:
b. 0.25
c. 0.05
d. 0.05
e. 0.25
Step-by-step explanation:
if the waiting time x follows a uniformly distribution from zero to 20, the probability that a passenger waits exactly x minutes P(x) can be calculated as:

Where a and b are the limits of the distribution and x is a value between a and b. Additionally the probability that a passenger waits x minutes or less P(X<x) is equal to:

Then, the probability that a randomly selected passenger will wait:
b. Between 5 and 10 minutes.

c. Exactly 7.5922 minutes

d. Exactly 5 minutes

e. Between 15 and 25 minutes, taking into account that 25 is bigger than 20, the probability that a passenger will wait between 15 and 25 minutes is equal to the probability that a passenger will wait between 15 and 20 minutes. So:

Add them all up and divide by 30. Answer: $55.20.
Answer:
x=-2y-6
Step-by-step explanation:
Subtract 2y from both sides, and now you have x=-2y-6.
