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

Q1) Jane Botosan operates a bed and breakfast hotel in a resort area near Lake Michigan. Depreciation on the hotel is $60,000 per year. Jane employs a maintenance person at an annual salary of $41,000 and a cleaning person at an annual salary of $24,000. Real estate taxes are $10,600 per year. The rooms rent at an average price of $127 per person per night including breakfast. Other costs are laundry and cleaning service at a cost of $10.6 per person per night and the cost of food which is $5.8 per person per night.

A) Determine the sales revenue Jane needs to break even.

B) Determine the number of rentals Jane needs to earn a target net income of $50,000.

C) Jane is considering changing the business strategy. She considers installing additional cleaning machines which will decrease laundry and cleaning service per person per night by $3. However, fixed depreciation cost will increase by $4,080. Determine the number of rentals Jane needs to break even if the changes are made.

D) Determine the number of rentals at which Jane would be indifferent between the current and proposed business models. (Hint: Consider net income figures.)

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.

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

Suppose General Motors demands labor according to the labor demand function ? = 40 − 0.5?, where ? is the hourly wage and ? is the number of employees. The United Auto Workers Union has a utility function given by ? = ? ∗ ?.

a. In 1984, the United Auto Workers Union started negotiations with General Motors by assuming that they were a monopoly union. Find the wage and employment demands that the United Auto Workers Union would have demanded before any bargaining began.

b. If General Motors and the United Auto Workers Union both had excellent bargaining representatives, would this be the final labor contract? If not, then explain in words and graphically where they would end up after the bargaining process.

A survey of a sample of 26 hotels in New Orleans found that the average hotel room rate s $88.42 with a standard deviation of $5.62 and another survey of 25 hotels in the Phoenix area found that the average room rate is $80.61. Assume with a standard deviation of $4.83. At α =  0.05, can it be concluded that there is a significant difference in the rates?

When using calculator and when it comes to choose Yes or No for pooled, keep it at the default No.
Here is what pooled means: If we assume that population variances are equal we select YES and if we assume that population variances are not equal, we select No. By default, use No unless if it is specified otherwise.

Because of staffing decisions, managers of the Gibson-Marimont Hotel are interested in the variability in the number of rooms occupied per day during a particular season of the year. A sample of 24 days of operation shows a sample mean of 299 rooms occupied per day and a sample standard deviation of 32 rooms.
