Determine the sample regression equation that enables us to predict the price of a sedan on the basis of its age and mileage. (Negative values should be indicated by a minus sign. Round your answer to 2 decimal places.) Priceˆ = + Age + Miles. b. Interpret the slope coefficient of Age. The slope coefficient of Age is −487.30, which suggests that for every additional year of age, the predicted price of car decreases by $487.30. The slope coefficient of Age is −0.08, which suggests that for every additional year of age, the predicted price of car decreases by $0.08. The slope coefficient of Age is −487.30, which suggests that for every additional year of age, the predicted price of car decreases by $487.30, holding number of miles constant. The slope coefficient of Age is −0.08, which suggests that for every additional year of age, the predicted price of car decreases by $0.08, holding number of miles constant. c. Predict the selling price of a eight-year-old sedan with 68,000 miles. (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Priceˆ = $

Mount Alberta in Jasper National Park, Alberta, has an elevation of 3620 m above sea level. Determine the atmospheric pressure at the top of Mount Alberta, assuming a sea level pressure of 101 kPa and a temperature of 12°C. (Consider that the average molar mass of air is 29 g/mol.)

Have you ever ridden a free-fall ride at an amusement park, where the riders are suspended at a terrifying height and then plummet towards the ground in free fall? These rides use a Lenz’s law mechanism to slow the drop. Explain how Lenz’s law applies to this situation and why this mechanism is ideal for such an application.

2. According to Newton’s Law of Cooling, the rate of change of the temperature of an object can be modeled using the following differential equation:

dT/dt = k(T-T_R)

where T is the temperature of the object (in ◦F), TR is the room temperature (in ◦F), and κ is the constant of proportionality.
On a crime show, the detective discovers a dead body in a hotel room.
(a) Write the differential equation to describe the change in temperature of the body if κ = −0.405 and thermostat in the hotel room is set at 70◦F.
(b) Solve the differential equation using an appropriate method. State the method you used and show your work.
(c) Assuming the victim was a healthy 98.6◦F at the time of the murder, we have the initial condition that T(0) = 98.6. Find the particular solution to the IVP.
(d) If the body temperature is 85◦F when the crime scene is discovered, how long has the victim been dead? (Assume t is measured in hours.)

Administration                        140,000                         1,102,000

Loss                                                                                 (2,000)

Additional Information:

1. Number of rooms available        100 per day

2. Occupants days                         24,000 per annum

You are required to compute:

(i)   The contribution margin ratio.

(ii) The break-even point in both occupants’ days and occupants’ charges.

(iii) The margin of safety ratio if the Hotel operates at fully capacity.

(iv) The break-even points one occupants’ days of direct salary were

increased to GHS626,000.

(v) The break-even in occupants’ days if fixed occupants service overheads were increased to GHS145,000.

Case 401

Hotel Front Office Management

Ana Chavarria, front office manager, and Lorraine DeSantes, director of marketing and sales, have just returned from a computer conference at which they were able to look at the latest property management systems for hotels. Ana is enthusiastic about updating and adopting front office applications for reservations, registration, room status, posting, call accounting, checkout, and night audit. Lorraine is sure the marketing and sales applications will help her department be more efficient. Both realize the cost involved in obtaining modules for a property management system. What would you suggest they do prior to discussing this issue with Margaret Chu, general manager of The Times Hotel? Assuming Ms. Chu is willing to consider the purchase of a PMS, how should Ana and Lorraine proceed? Whom should they include in developing a PMS adoption plan, and why? What areas should they investigate?

Question:Bianca was hired to drive an airport shuttle for a hotel. When Bianca was hired, she signed a written contract that stated specifically that she was an independent contractor. The hotel pays her by the hour and makes no withholding from her pay for taxes. She drives the hotel’s van and wears the required uniform when she is on duty. She is on-call twenty-four hours per day and she transports the hotel’s guests back and forth to the airport at the hotel’s request. Is Bianca an employee or independent contractor? Explain and provide thorough legal analysis.
