Two possible routes for a power line are under study. In both cases, the power line will last 15 years, have no salvage value, have annual property taxes of 2% of first cost, and have a yearly power loss of $500/km.

The president of Doerman Distributors, Inc., believes that 25% of the firm's orders come from first-time customers. A random sample of 100 orders will be used to estimate the proportion of first-time customers.

(a)

Assume that the president is correct and

p = 0.25.

What is the sampling distribution of

p

for n = 100? (Round your answer for

σp

to four decimal places.)

σp

=

E(p)

=

Since np = and n(1 − p) = , approximating the sampling distribution with a normal distribution

appropriate in this case.

(b)

What is the probability that the sample proportion

p

will be between 0.15 and 0.35? (Round your answer to four decimal places.)

(c)

What is the probability that the sample proportion will be between 0.20 and 0.30? (Round your answer to four decimal places.)

The president of Doerman Distributors, Inc., believes that 30% of the firm's orders come from first-time customers. A random sample of 100 orders will be used to estimate the proportion of first-time customers.

What is the maximum American opportunity tax credit that Elaine can claim for the tuition payment and books in each of the following alternative situations? (Leave no answer blank. Enter zero if applicable.)

a. Elaine’s AGI is $80,000. b. Elaine’s AGI is $168,000. c. Elaine’s AGI is $184,000.

A mother has brought her 4-year-old daughter to the emergency department. She didn't realize her husband had sprayed the lawn with a pesticide and allowed their daughter to play in the yard. She now comes in with complaints of nausea, vomiting, difficulty breathing, and confusion.

A. How would you respond? What are you initial interventions? B. How can you help the family? C. What are some nursing diagnoses that would be appropriate for this situation?

The enzyme urease catalyzes the reaction of urea, (NH2CONH2), with water to produce carbon dioxide and ammonia. In water, without the enzyme, the reaction proceeds with a first-order rate constant of 4.15 ×10−5s−1 at 100 ∘C. In the presence of the enzyme in water, the reaction proceeds with a rate constant of 3.4 ×104s−1 at 21 ∘C

1.If the rate of the catalyzed reaction were the same at 100 ∘C as it is at 21 ∘C, what would be the difference in the activation energy between the catalyzed and uncatalyzed reactions? Express your answer using two significant figures.

2.

In actuality, what would you expect for the rate of the catalyzed reaction at 100 ∘C as compared to that at 21 ∘C?

In actuality, what would you expect for the rate of the catalyzed reaction at 100  as compared to that at 21 ?

After running the experiment with the pivot, comment out the line, update the pivot selection to use the median of the first, middle, and last items, and run the experiment.

What line needs to be commented out and how would I update the pivot selection to use the median?

Example:

Consider two projects. The first project pays benefits of $90 today and nothing else. The second project pays nothing today, nothing one year from now, but $100 two years from now. Which project would be preferred if the discount rate were 2%? What if the rate increased to 10%?

- For a discount rate of 2%, the present value calculations would be $90 for project one and $96.12 for project two; therefore, project two is preferred. At a rate of 10%, the PV of project one is still $90. For project two, the PV is now 100/1.1^2= 82.6; therefore, project one is preferred.

How can I solve this questions below???????????????????????????????????

Consider two projects. The first project pays benefits of $90 today and nothing else. The second project pays nothing today, nothing one year from now, but $100 two years from now. Which project would be preferred if the discount rate were 2%? What if the rate increased to 8%?

Part 2: An electric company charges to their customers based on Kilowatt-Hours (Kwh) used. The rules to compute the charge are: First 100 Kwh, 35 cents per Kwh Each of the next 100 Kwh (up to 200 Kwh), 45 cents per Kwh (the first 100 Kwh used is still charged at 35 cents each) Each of the next 300 Kwh (up to 500 Kwh) 65 cents per Kwh All Kwh over 500, 80 cents per KH Create a C# Form with a textbox to enter Kwh used, a read-only textbox to display the electricity charges, and a button to compute the charges. The Kwh used could be a number with decimals. Requirements: 1. Input validation: Use the KWH textbox validating event to ensure the KWH cannot exceed 2000. Test your program with (1) Kwh=4500, (2) Kwh = 350 2. Turn in the form’s screenshot and the code.
