The police that patrol a heavily traveled highway claim that the average driver exceeds the 65 miles per hour speed limit by more than 10 miles per hour. Seventy-two randomly selected cars were clocked by airplane radar. The average speed of the 72 cars was 77.40 miles per hour, and the standard deviation of these speeds was 5.90 miles per hour. Test a 5% level of significance whether the average speed by all drivers is more than 75 mph. Make sure to show all of your work and include every step.

An automobile takes 9.89 seconds to accelerate from rest to 60 miles per hour. a) Find the automobile's acceleration (assuming that is constant) and b) the distance traveled in reaching 60.0 miles per hours. Assuming that this acceleration remains constant over 0.25 miles, predict c) the time it takes to cover this distance and d) the car's velocity at the end. e) convert this velocity to miles per hour. f) sketch graphs of position, velocity, and acceleration versus time for this automobile.   

Imagine you are an automotive engineer for Toyoto Motor Corporation. You are test driving a new cruise control system, and you are driving around the test track at 55 miles per hour. You set the cruise control to 57miles per hour. The cruise controller takes over and speeds up to 59 miles per hour, then slows to 56 miles per hour, and finally settles at 58 miles per hour. Given this result, what adjustments would you make to the car's cruise control system to improve overall performance?  

Transit Railroads is interested in the relationship between travel distance and ticket class purchased. A random sample of 200 passengers is taken. The table below shows the results. The railroad wants to know if a passenger’s choice in ticket class is independent of the distance they must travel.

Three different companies each purchased trucks on January 1, 2018, for $76,000. Each truck was expected to last four years or 250,000 miles. Salvage value was estimated to be $6,000. All three trucks were driven 81,000 miles in 2018, 55,000 miles in 2019, 46,000 miles in 2020, and 71,000 miles in 2021. Each of the three companies earned $65,000 of cash revenue during each of the four years. Company A uses straight-line depreciation, company B uses double-declining-balance depreciation, and company C uses units-of-production depreciation. Answer each of the following questions. Ignore the effects of income taxes. b-1. Calculate the net income for 2021? (Round "Per Unit Cost" to 3 decimal places.)

Tasteful Pizza bought a used Toyota delivery van on January​ 2, 2016​, for $ 21,800. The van was expected to remain in service for four years left parenthesis 48,750 ​miles). At the end of its useful​ life, Tasteful officials estimated that the​ van's residual value would be $ 2,300. The van traveled 15,000 miles the first​ year, 17,000 miles the second​ year, 12,500 miles the third​ year, and 4,250 miles in the fourth year.

1. Prepare a schedule of depreciation expense per year for the van under the three depreciation methods.

2. Which method best tracks the wear and tear on the​ van?

3. Which method would Tasteful prefer to use for income tax​ purposes? Explain in detail why Tasteful would prefer this method.

5. Which company will report the lowest amount of cash flow from operating activities on the 2020 statement of cash flows?

A car service charges customers a flat fee per ride (which is higher during rush hour traffic) plus charges for each minute and each mile. Suppose that, in a certain metropolotian area during rush hour, the flat fee is $3, the cost per minute is $0.20, and the cost per mile is $1.20. Let x be the number of minutes and y the number of miles. At the end of a ride, the driver said that the passenger owed $20.60 and remarked that the number of minutes was five times the number of miles. Find the number of minutes and the number of miles for this trip.

A. Complete the equation that represents the total cost of the ride. ___=20.60

B. Complete the equation that represents the relationship between the number of minutes and number of miles. __=0

C. Find the number of minutes and number of miles for this trip.
