1. Air travelers are sometime annoyed to find that the price of a ticket for a short flight may exceed the price for a long flight. For example, a round-trip ticket from Chicago to Washington Seattle on the airline recently cost $235, compared with the same airline’s price of $278 from Chicago to Moline, which is just less than half an-hour flight, about 160 miles. Travelers complain that such prices represent unfair discrimination against the residents of a medium sized cities such as Moline or Davenport, Iowa. They say that airlines should charge prices that are proportional to the distance flown. The airlines answer that they can serve major city pairs, such as Chicago, Seattle, at a lower cost (with larger planes and fewer empty seats) than less frequently traveled city pairs, such as Chicago – Moline. Do you see the airlines pricing policy in this example as true price discrimination? Discuss the merits of the current price structure and proposed alternative in terms of fairness and efficiency.

1. Define the terms "geodetic height", "geoidal height", and "orthometric height", present the equation that expresses the relationship between the geodetic height and orthometric height, and state which one these heights are measured by GNSS survey method.

2. What are the geocentric coordinates in meters of a station which has a latitude of 44°53′52.1918′′ N, a longitude of 68°40′07.3487′′ W and height of 130.405 m (use the WGS84 ellipsoidal parameters)?

3. The geodetic heights of two stations are 324.685 m and 309.879 m, and their orthometric heights are 356.496 m and 341.707 m, respectively. These stations have model-derived geoid heights of −31.828 and −31.836, respectively. What is the orthometric height of a station with a GNSS measured height of 305.645 m and a model-derived geoid height of −31.802 m?

4. A GNSS survey has a reported error of ±(12mm + 2ppm) at a 95% probability. What is the error for a control baseline with a length of 4 miles at the 95% probability?

The district manager of basketball officials has to assign each team of officials to one game on Friday night.

There are four sites for games. So each site needs one group of officials. Below are the distances in miles each

group of officials is from each site.

Formulate the linear programming problem to minimize distance traveled by the groups of officials in this

assignment problem.

A-Which Group is assigned to each location?

B-what would happen to the distance traveled if instead of the best assignment we had Group A go to

Wayne, Group B to South Sioux City, Group C to Winnebago, and Group D to Wakefield?

Toyota’s marketing department is in the process of creating an ad meant to highlight the fuel efficiency of its Camry model compared to its Avalon model. Toyota knows that based on their production process, the miles per gallon (mpg) of both the Camry and the Avalon follow a normal distribution with the Camry having a standard deviation of 1.5 mpg and the Avalon having a standard deviation of 3.6 mpg. Toyota takes a sample of 50 Camry models and 60 Avalon models and finds that the Camry has a mean mpg of 31 while the Avalon has a mean mpg of 29.5 mpg. Toyota would like to know if there is sufficient evidence, at the alpha=0.01 level, to conclude that the Camry has a higher mpg than the Avalon. Answer the following questions.

1. What are the null and alternative hypotheses?

2. What is the critical value?

3. What is the test statistic?

4. What is the probability that you will find the Camry has a higher mpg but really it does not?

5. Will you reject or fail to reject the null hypothesis?

class Car:

condition = "new"

def __init__(self, model, color, mpg):

self.model = model

self.color = color

self.mpg = mpg

my_car = Car("Corvette", "Black", “30”)

print my_car.model

print my_car.color

print my_car.MPG

print my_car.condition

Add class “getter” methods to return the values for model, color, and MPG

Add class “setter” methods to change the existing values for model, color, and MPG. The value to be used in the methods will be passed as an input argument.

Add class method that will calculate and return the number of miles driven, where the method is provided the size of the gas tank as an integer input

Below your Car class, create a new child class called mySportsCar that inherits from Car class. Make sure you call the Car class constructor with the appropriate inputs in the child class constructor.
Instantiate an object of the mySportsCar class. Use whatever appropriate input values that you would like.

Marsha Jones has bought a used Mercedes horse transporter for her Connecticut estate. It cost $43,000. The object is to save on horse transporter rentals.

Marsha had been renting a transporter every other week for $208 per day plus $1.40 per mile. Most of the trips are 80 or 100 miles in total. Marsha usually gives Joe Laminitis, the driver, a $35 tip. With the new transporter she will only have to pay for diesel fuel and maintenance, at about $0.53 per mile. Insurance costs for Marsha’s transporter are $1,600 per year.

The transporter will probably be worth $23,000 (in real terms) after eight years, when Marsha’s horse Spike will be ready to retire. Assume a nominal discount rate of 9% and a 2% forecasted inflation rate. Marsha’s transporter is a personal outlay, not a business or financial investment, so taxes can be ignored.

Calculate the NPV of the investment.

When traveling through mountains, most highways periodically have emergency escape ramps to allow large, heavy vehicles to stop safely, even when their brakes are not working properly. One such escape ramp is angled 13 ∘ above the horizontal. The brakes on one large truck (mass 1.4×10⁴ kg ) fail when driving at a speed of 80 miles per hour (35.75 m/s), and the driver makes use of the escape ramp.

Part A: What is the minimum length of ramp necessary for this truck to come to a stop? Assume negligible friction and air resistance forces.

Part B: If instead dissipative forces (friction and air resistance) provide a constant force of 60,000N parallel to the ramp, what is the minimum length of ramp necessary for this truck to come to a stop?

my answer for part A is 290 m, but I am unsure how to get the answer for part B. please help

George and Martha have $6000 in a checking account that pays no interest. They want to buy their first car right now, and at the same time save monthly toward a house. The plan is to drive the car for 5 years, then sell it the same month they put the money down on the house. You have been asked to help them decide which car to buy and to determine, based on their plan, the highest price house they can afford to buy.

Part 1

Buying the car. They have narrowed their choice to two models, one from dealer A and one from dealer B.

Cost of operating the car. In addition to their monthly car payments, G&M will need to buy gas, change the oil, and pay for insurance.  

• They assume gas will average $2.60/gallon over the next 5 years. They drive 20,000 miles each year.

• Oil changes are $60 every 5000 miles.

• Insurance and licensing fees are based on the car price, and they figure that 5% of the full price each year will suffice to cover both.

Calculate:

1. Monthly and total (5-yrs) payments for both car options (make sure you calculate the monthly payments only on the amount you are borrowing!)

2. Monthly and 5 year operating cost for both car options, and  

3. Total cost of ownership of each car option over the 5 years.  

4. Choose the car you think George and Martha should purchase and explain why you chose the car you did. You will use the costs of the car you chose to complete Part 2.

Part 2

Buying the house

• The car down payment will come from their bank account, and whatever is left will stay in the checking account as a cash reserve.  

• After all their other monthly expenses, G&M have a net positive cash flow of $1400. They will make the monthly car payments, insurance payments, gas and oil payments from their cash flow of $1400 (so monthlies can never be more than this amount).  

• Any excess cash (from the $1400) will go into a long term savings plan for 5 years that pays an APR of 6% compounded monthly.  

• At the end of the five years, they will sell the car and cash out the long term savings plan, put the amount of their original car down payment back in checking so they can shop for a new car.

• The remaining long term savings plan balance they will use as a down payment on a new house, which they expect to be 15% of the house’s price.

Calculate:

1. Total funds in the long term savings plan after 5 years,  

2. Funds available for a down payment on a house,  

3. Highest house price they can afford, and  

4. Monthly payment for a 30-year mortgage at 4.5% APR  

Part 3  

Report to George and Mary

Now that you have completed your calculations, it is time to create a report for George and Mary, outlining your recommendations to them. In this report you should include the following:

• The recommended car purchase, with a written justification, referencing the formulas and your calculations,

• A written explanation of how you arrived at the amount to be saved monthly, referencing the formulas and your calculations, and

• A written explanation of how you determined the most expensive house they can afford, and the monthly payment resulting from the purchase of that house.

Description

CSCI 1151, Fall 2019 Programming Assignment 5 – Structure

Construct an array of a structure to store the information of vehicles. This structure should consist of: an integer for the vehicle identification number (ID); an integer for the mile driven; an integer for the number of gallons used by the vehicle; and a string for the vehicle’s manufacture. Write a C program that get (input) the information of the vehicles from a file, cardb.txt, one structure per vehicle.

Your program should sort the vehicles by their identification numbers (ID) in ascending order. Prompt the user to enter the vehicle ID number and apply binary search for the vehicle. Output the information of the vehicle on the console, if the vehicle is not found then output “Vehicle not found”. Assume the maximum number of vehicles is 100 which means you need to allocate an array of size 100 of the structure you declared. You may use dynamic memory allocation to get exact memory size. There will be an extra 20 points if you use dynamic memory allocation.

Input

File name: cardb.txt

Output

1. 1) You need to have at least two functions, sort() and search(), in your program. You may implement any sorting algorithm for your sort() function to sort the vehicles, you have to implement the binary search algorithm for your search() function for searching vehicles, the search key is the vehicle ID number.

2. 2) To test your sorting, you should output the vehicle information on the console (refer to the sample output example).

3. 3) A while loop continue prompt user for the vehicle ID number and output the information of the searched vehicle on the console. If not find, then output “Vehicle not found”. After receive a negative vehicle ID number from the user, the while loop will be terminated.

Format of the Input File

Up to 100 records, one per vehicle, a new line between two adjacent records
Four fields (columns) per records (line): vehicle ID number, Miles Driven, Gallons of Gas used, Vehicle Manufactural. A blank (space) between adjacent fields. Refer to the attached file cardb.txt

Explain why this statement is false: Since there are many hotels and many hotel customers in San Francisco, it is definitely appropriate to use the supply and demand model to analyze the market for hotel rooms in San Francisco. [Hint: Under what circumstances is the supply and demand model appropriate?]
