The Fuel Efficiency data for 500 cars is attached. The column labeled Manufacturer shows the name of the company that manufactured the car; the column labeled Displacement shows the engine’s displacement in liters; the column labeled Fuel shows the required or recommended type of fuel (regular or premium gasoline); the column labeled Drive identifies the type of drive (F for front wheel, R for rear wheel, and A for all wheel); and the column labeled Hwy MPG shows the fuel efficiency rating for highway driving in terms of miles per gallon. Analyzing Environment Canada’s Fuel Economy Guide data, write a briefing report that will help the trade department decide on import quota restrictions that may take either fixed in terms of value or quantity of the cars which can be imported over the coming decades.

A second purchase, at the same prices, included 18 rolls of resistance bands and 24 therapy balls. The cost of the second purchase was $505.50. Find the unit cost for a resistance band and the unit cost for a therapy ball. Cost of Resistance Band = $ Cost of Therapy Ball = $ Round to the nearest centarrow_forward

A friend who lives in Los Angeles makes frequent consulting trips to Washington, D.C.; 60% of the time she travels on airline #1, 20% of the time on airline #2, and the remaining 20% of the time on airline #3. For airline #1, flights are late into D.C. 40% of the time and late into L.A. 10% of the time. For airline #2, these percentages are 30% and 25%, whereas for airline #3 the percentages are 20% and 10%. If we learn that on a particular trip she arrived late at exactly one of the two destinations, what are the posterior probabilities of having flown on airlines #1, #2, and #3? Assume that the chance of a late arrival in L.A. is unaffected by what happens on the flight to D.C.arrow_forward

- Provide a step by step solution. Thank you! A new airline has decided to join the market. It is considering offering flights out of Cagayan, and would initially like to travel to three different locations: Cebu, Palawan, and Bohol. The distances of each round-trip flight going out of Cagayan are (approximately): 720 miles, 1500 miles, and 1140 miles, respectively. The company would like to use the slogan, "the average price per flight is never more than P10, 000." As for costs, it anticipates flights to Cebu will run about 10% of airfare. Similarly, Palawan will run 12% and Bohol will run 14% of airfare. The company wants to ensure that the overall average cost is no more than 10% of earned airfare. Recent market research allows the company to conclude that it could probably sell about 1900 Cebu tickets, 700 Palawan tickets, and 1000 Bohol tickets. Under these conditions and assuming that all tickets sold are round-trip flights, how much should the company charge per ticket in order to…arrow_forwardDONT WRITE IN HAND WRITTEN FORM Bevco manufactures an orange flavored soft drink called Oranj by combining orange soda and orange juice.
