The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 2800 miles.
Use 100,000 or -100,000 as the upper or lower bound where necessary.
a. What is the probability a particular tire of this brand will last longer than 57,200 miles?
b. What is the probability a particular tire of this brand will last less than 58,000 miles?
c. What is the probability a particular tire of this brand will last between 56,850 miles and 57,300 miles?

1. A tire company produces a tire that has an average life span
of 500 miles with a standard deviation of 250. The distribution of
the life spans of the tires is normal. What is the probability that
the tires lasts between 530 and 375 miles? (Round three decimal
places)
2. A tire company produces a tire that has an average life span of
480 miles with a standard deviation of 30. The distribution of the
life spans of the tires is normal. What is the probability that the
tires lasts less than 430 miles? Round your answer to three decimal
places
3. A tire company produces a tire that has an average life span of
480 miles with a standard deviation of 25. The distribution of the
life spans of the tires is normal. What is the probability that the
tires lasts greater than 498 miles? (Round three decimal
places)

Chubbyville purchases a delivery van for $23,100. Chubbyville estimates that at the end of its four-year service life, the van will be worth $1,900. During the four-year period, the company expects to drive the van 109,000 miles. Calculate annual depreciation for the four year life of the van using straight line, double declining, and activity based.

You need to travel 100 miles via rental car. There are several cars on the lot to choose from, each with their own MPG (miles per gallon) rating. Some cars have a manual transmission, while others do not (they're automatic). The price for gas in the area is $3 per gallon. Cars that have a manual transmission get a 10% discount at the pump.
To streamline your selection, the car rental place can supply you with a dictionary that represents the cars on their lot. The keys of this dictionary are names of cars, and their values are another dictionary. The inner dictionary has a key for the MPG of this car, and a key for whether or not the car is manual.
Write a function called def cheapest(cars) that returns the name of the car that costs the least amount of money to travel 100 miles.
Here is an example (there could be more than just two cars):
cars_on_lot = {'Civic':{'mpg':40,'manual':True},'Volt':{'mpg':50,'manual':False}}
print(cheapest(cars_on_lot)) # Volt
The "Civic" gets 40 miles to the gallon and is a manual transmission. 100 miles in this car requires 2.5 gallons of gas. The manual transmission deduction is $0.75. Therefore, it costs $6.75 to travel 100 miles in this car.
The "Volt" gets 50 miles to the gallon but is not a manual transmission. 100 miles in this car requires 2 gallons of gas. There is no manual transmission deduction. Therefore, it costs $6 to travel 100 miles in this car.
Of these two options, the Volt is the cheapest car you can use to travel 100 miles.

Miles to Kilometers
ASSIGNMENT:
Write a program to convert miles to kilometers. Put the entire program in a sentinel-controlled loop that runs until the user enters a negative number. Use both a pre-test sentinel-controlled loop and a post-test sentinel-controlled loop in the program.
There are 1.6 kilometers in 1.0 mile. Store the value of 1.6 in a constant and use the constant in the calculations.
There is 1 blank line after the descriptions, and 2 blanks lines between the pre-test and the post-test parts of the program.
Use singular/plural decisions for both miles and kilometers.
There is no validation.
Example Run #1:
(bold type is what is entered by the user)
*** Using a pre-test (while) loop ***
*** This requires the initial prompt and get before the loop,
*** and the loop itself must end with a re-prompt and re-get,
*** but it doesn't require a decision inside the loop.
*************************************************************
Enter the number of miles (enter a negative number to quit):
1.0
1.0 mile is 1.6 kilometers.
Enter the number of miles (enter a negative number to quit):
-1
*** Using a post-test (do) loop ***
*** This requires a decision inside the loop to see
*** if the process and output should be done,
*** but the prompt is only written once.
*************************************************************
Enter the number of miles (enter a negative number to quit):
0.625
0.6 miles is 1.0 kilometer.
Enter the number of miles (enter a negative number to quit):
5.5
5.5 miles is x.x kilometers.
Enter the number of miles (enter a negative number to quit):
-1
The example run shows EXACTLY how your program input and output will look.

Project 1: Frequent Flyer Miles Calculator
Write a Ruby program that calculates how many frequent flyer
miles are needes for a free ticket on a new startup airline,
CorsairAir. Frequent flyer miles are charged for a free ticket
depending on the class of service (more for first class, less for
coach), depending on the day flying (more if flying on Friday,
Saturday or Monday, less for other days of the week), depending on
the distance traveled, and a surcharge if flying to Canada, Mexico
or the Carribean. Tickets start with a cost of 10,000 frequent
flyer miles. Then, you should calculate the distance charge which
is 1,000 frequent flyer miles for each 250 miles flown. Then, you
should charge an additional 40% charge of frequent flyer miles if
the passenger wants to fly first class. If flying on a Friday,
Saturday or Monday, the ticket will cost an additional 5,000
frequent flyer miles. Travel to Canada, Mexico or the Carribean
needs to cost an additional 7,500 frequent flyer miles. Be sure
your program does not allow for negative miles flown or incorrect
answers to the yes/no questions asked.
The sample program dialogs below should help you to see how to
perform this calculation.

the average annual miles driven per vehicle in the United States is 11.1 thousand miles, with σ ≈ 600 miles. Suppose that a random sample of 36 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.8 thousand miles. Does this indicate that the average miles driven per vehicle in Chicago is different from the national average? Use a 5% level of significance.
