If a firm adjusted their prices to be high enough to cover their Average Total Costs and if they were not concerned with MC=MR, then we could probably assume they are a nonprofit entity.        

True or False

Who will really end up paying for higher taxes on corporate profits if we assume the product that they sell is very inelastic?

Multiple Choice

• The stockholders of the firm will pay this tax when they file their individual tax returns.

• The retail consumer will pay these taxes through higher prices.

• The state government pays these taxes to the federal government

• 1. The senior executives actually pay these taxes when they file their individual tax returns.

If we took an elastic demand curve and raised the price, then this would be the best pricing strategy to maximize total revenue.

True or False

A sample of size 27 will be drawn from a population with mean 4 and standard deviation 3.

(a) Is it appropriate to use the normal distribution to find probabilities for x?

(b) If appropriate find the probability that x will be greater than 2.

(c) If appropriate find the

40th percentile of x.

25 , 26 , 26 , 27 , 28 , 31 ,40 ,41

27. The nurse is caring for a client with a nursing diagnosis of impaired skin integrity related to a stage III pressure ulcer. What would be the most important outcome for this client?

A. The client keeps the area clean and dry

B. The nurse turns the patient every two hours

C. The client does not exhibit any signs or symptoms of infection

D. The client is unaware of the prevention measures for pressure ulcers

Suppose x has a distribution with a mean of 70 and a standard deviation of 27. Random samples of size

n = 36

are drawn.

(a) Describe the

x distribution

and compute the mean and standard deviation of the distribution.

x

has  ---Select--- a binomial a geometric a Poisson a normal an approximately normal an unknown distribution with

mean μ_x =

and

standard deviation σ_x =  .

(b) Find the z value corresponding to

x = 61.

z =

(c) Find

P(x < 61).

(Round your answer to four decimal places.)

P(x < 61) =

(d) Would it be unusual for a random sample of size 36 from the x distribution to have a sample mean less than 61? Explain.

No, it would not be unusual because more than 5% of all such samples have means less than 61.Yes, it would be unusual because less than 5% of all such samples have means less than 61.    Yes, it would be unusual because more than 5% of all such samples have means less than 61.No, it would not be unusual because less than 5% of all such samples have means less than 61.

Carolyn Shaw is 27. - She works as an accountant for an oil company. - Her salary next year will be $80,000. - She expects to receive a 5 percent raise each year until she retires at age of 65. - Carolyn is considering a return to school to pursue an MBA degree. - She expects the cost of books, tuition, and fees to be $70,000 the first year and $72,000 the second. - These costs are paid at the beginning of the year (as you surely know). - She will not work while in school. - Graduates of the school Carolyn is considering receive starting salaries that average $130,000. - Raises average 7 percent per year. - Carolyn considers the opportunity costs to be 12 percent. a)Determine the present value of Carolyn’s lifetime earnings if she does not return to school. b)Determine the present value of Carolyn’s lifetime earnings with an MBA degree. Remember, she won’t start her job for two years. c) What is the NPV of an MBA degree given Carolyn Shaw's assumptions?

Find the duration of a bond with a settlement date of May 27, 2023, and maturity date November 15, 2034. The coupon rate of the bond is 6.5%, and the bond pays coupons semiannually. The bond is selling at a bond-equivalent yield to maturity of 7.5%. Use Spreadsheet 16.2. (Do not round intermediate calculations. Round your answers to 4 decimal places.)

Assume that the gene trpA in an auxotrophic strain of E. coli is located at 27 minutes, whereas the gene pyrE is located at 81 minutes.
Present an experimental scheme that would allow you to convert one of the auxotrophic strains to a prototrophic strain.

A. F⁺ (auxotroph) × F⁻ (wild type)

B. Hfr (auxotroph) × F⁻ (auxotroph)  

C. Hfr (auxotroph) × F⁻ (wild type)

D. Hfr (wild type) × F⁻ (auxotroph)

E. F⁺ (wild type) × F⁻ (auxotroph)

The correct answer is D, but I don't understand why. Could someone explain this? Thank you!
