Answer:
Jessica pays $10 more than Nancy for membership fee.
Step-by-step explanation:
Jessica pays a membership fee of $40, and she pays $5 for every video game she rents.
So, we can write this as :
'x' is the number of games rented.
And equation for Nancy is :
If we look at the equations we can find that, the numbers 40 and 30 are constant i.e the membership fee.
And 5x and 4x are variable terms that change with the number of games rented.
So, Nancy's membership fee is $30. This is dollars less than Jessica.
Therefore, Jessica pays $10 more than Nancy for membership fee.

<span>f = v + at
Subtract v from both sides.
f - v = at
Divide both sides by a.
(f - v)/a = t
Switch sides.
t = (f - v)/a

Subtract v from both sides.
f - v = at
Divide both sides by a.
(f - v)/a = t
Switch sides.
t = (f - v)/a
Answer: a) 0.9961, b) 0.9886
Step-by-step explanation:
Since we have given that
Probability that does not show up = 0.10
Probability that show up = 0.90
Here, we use "Binomial distribution":
n = 125 and p = 0.90
Number of passengers that hold in a flight = 120
a) What is the probability that every passenger who shows up can take the flight?
(b) What is the probability that the flight departs with empty seats?
Hence, a) 0.9961, b) 0.9886
