Aliens are observing a park in new york. They notice a merry-go-round has a radius of 3.12m and a moment of inertia of 3100kgm^2 at the vertical axis through the center. The contraption has been lubricated recently so there is no friction. one of the earthlings applies a tangential force of 19N for 13s begging at rest. Unfortunaley after gathering this data the aliens computer broke so now they must calculate the work that was done over the course of the 13s.

Exercise 5A-2 Least-Squares Regression [LO5-11]

Bargain Rental Car offers rental cars in an off-airport location near a major tourist destination in California. Management would like to better understand the variable and fixed portions of it car washing costs. The company operates its own car wash facility in which each rental car that is returned is thoroughly cleaned before being released for rental to another customer. Management believes that the variable portion of its car washing costs relates to the number of rental returns. Accordingly, the following data have been compiled:

Exercise 5A-2 Part 2

2. Using least-squares regression, estimate the variable cost per rental return and the monthly fixed cost incurred to wash cars. (Round Fixed cost to the nearest whole dollar amount and the Variable cost per unit to 2 decimal places.)

Tommy Shelby lives in Mahebourg. On 15 June 2020, he lost his job as bartender in a hotel in the southern part of Mauritius, due to the COVID-19 pandemic. He was offered Rs200,000 as severance allowance, for his 5 years of loyal service to the hotel. Taking into consideration the craze which online purchases took during the national confinement period, he is now thinking of investing the severance allowance money, to launch an e-commerce website for the sales of products. He is thinking of selling all types of tangible products that can be ordered online. He intends to earn a percentage of all sales made online, through his platform.
However, Tommy Shelby neither has any knowledge of information systems, nor any experience in electronic business. Therefore, your contribution is required to help Tommy Shelby set up his business by working out the following assignment.
1. Use the Porter 5 Forces Model to analyse the market viability for Tommy Shelby’s business.
2. Discuss how the STEEPLED factors can influence internationalization of Tommy Shelby’s e-commerce platform.
3. Define the strategies that Tommy Shelby need to put in place for his business to succeed and sustain.

1) A new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 63women over the age of 50 used the new cream for 6 months. Of those 63women, 36 of them reported skin improvement(as judged by a dermatologist). Is this evidence that the cream will improve the skin of more than 60% of women over the age of 50?

What's the process of each one and result? A singer quartet consisting of Angel, Betty, Carlos and Diana wants to practice their singing. However due to the pandemic they decide to do so at a baseball park to keep social distancing. Angel stands on the home plate, Betty goes to third base, Carlos to second base and Diana to first base. While they are getting ready a bird flies along the line joining third base and home, Betty says “That bird is singing at a frequency of 350 hertz”, but Angel says “No, it is singing at 340 hertz.” Soon after the bird leaves the park Diana sings a 440 hertz note, Carlos hears it 0.1 second later and sings a 261 hertz note. Part a Make a drawing of the bird’s flight path along the line joining third base and home, with an arrow indicating the direction of flight, towards home or away from home. Part b Explain why you chose that direction, include any equations that support your explanation. Part c How far is Carlos from Diana? Show your calculations. Part d What is the period of Carlos’ note at 261 Hertz. Include your calculations

1. On Friday March 10th 2017, around 11pm your instructor Mr. Tamba Yaradouno was at O'Hare International Airport in Chicago picking up a relative. At the passengers arrival what they call "Vestibule" or numbered gates, he could not park and waited for long. The area was packed, airport security cars flashing lights everywhere not allowing anyone to park but just enough time to pick up people.

On Friday October 12th 2018 at about same time your instructor was at the same spot of that airport to surprisingly notice that the area was completely empty and sat there for almost two hours.

Explain in your words in two pages including graphs (hand written or typed, Microsoft office word, times new roman, 12 fonds, double spaced):

a. What has happened to the demand curve of tourists visiting Chicago and the USA in general.

b. What could happened to both demand and supply curves of airport jobs, to the international flights into the USA if this trend of tourists decline continue.

Note: Do not include COVID- 19 here, this is the change of the world view of the USA from the Obama administration compared to President Trump and thus the changes of the number of tourists visiting USA
