1.Find the following values, using the equations, and then work the problems using a financial calculator to check your answers. Disregard rounding differences. (Hint: If you are using a financial calculator, you can enter the known values and then press the appropriate key to find the unknown variable. Then, without clearing the TVM register, you can "override" the variable that changes by simply entering a new value for it and then pressing the key for the unknown variable to obtain the second answer. This procedure can be used in parts b and d, and in many other situations, to see how changes in input variables affect the output variable.)

a. An initial $400 compounded for 1 year at 8.8%. Round your answers to the nearest cent.
$  
b.An initial $400 compounded for 2 years at 8.8%. Round your answers to the nearest cent.
$  
c.The present value of $400 due in 1 year at a discount rate of 8.8%. Round your answers to the nearest cent.
$  

d..The present value of $400 due in 2 years at a discount rate of 8.8%. Round your answers to the nearest cent.
$  

2. Find the future value of the following annuities. The first payment in these annuities is made at the end of Year 1, so they are ordinary annuities. Round your answers to the nearest cent. (Notes: If you are using a financial calculator, you can enter the known values and then press the appropriate key to find the unknown variable. Then, without clearing the TVM register, you can "override" the variable that changes by simply entering a new value for it and then pressing the key for the unknown variable to obtain the second answer. This procedure can be used in many situations, to see how changes in input variables affect the output variable. Also, note that you can leave values in the TVM register, switch to Begin Mode, press FV, and find the FV of the annuity due.)

a $200 per year for 10 years at 8%.
$  
b. $100 per year for 5 years at 4%.
$  
c. $200 per year for 5 years at 0%.
$  

Now rework parts a, b, and c assuming that payments are made at the beginning of each year; that is, they are annuities due.

d. $200 per year for 10 years at 8%.
$  
e. $100 per year for 5 years at 4%.
$  
f. $200 per year for 5 years at 0%.

GREEN NEW DEAL

1.This deal states that we need to be net-zero global emissions by 2050. You saw a graphic on class Monday, showing how the U.S. could be 100% renewable by 2050. What is the biggest challenge you see to applying this on a global scale?

2.. I read Fox News’ assessment of the Green New Deal. They said if we make the switch to 100% renewables, it would result in the BIRD-pocylypse: “untold millions of birds being slaughtered by Democrats’ supposedly ‘environmentally friendly’ green energy sources, including wind farms and solar energy facilities.” Do you agree or disagree with this retort? Explain your position here

3.. The latest science says we have just 12 years to complete the energy and economic overhaul necessary to limit warming to a manageable level and avoid the worst consequences. These are HUGE goals, perhaps not accomplishable in our lifetimes, BUT we can take baby steps, right? Which “baby step” do you think should be addressed first – and how?

A research group conducted an extensive survey of 2853 wage and salaried workers on issues ranging from relationships with their bosses to household chores. The data were gathered through hour-long telephone interviews with a nationally representative sample. In response to the question, "What does success mean to you?" 1528 responded, "Personal satisfaction from doing a good job." Let p be the population proportion of all wage and salaried workers who would respond the same way to the stated question. How large a sample is needed if we wish to be 95% confident that the sample percentage of those equating success with personal satisfaction is within 1.8% of the population percentage? (Hint: Use p ≈ 0.54 as a preliminary estimate. Round your answer up to the nearest whole number.)

the department of energy website contains information about monthly wholesale and retail prices for natural gas in each state. go to www.eia.doe.gov/naturalgas/data.cfm and then click on the link monthly wholesale and retail prices. Under area, choose a state of interest to you, make sure the period Is monthly, and then under residential price click on view history. A window will open with a time plot covering approximately a 25-year period, along with a table of the monthly residential prices for each year.

(a) If you have access to statistical software, you should use the downland data (xls file) link to save the data as an excel (.xsl) file on your computer. Then enter the data into your software package and reproduce the time-series plot using the graphic capabilities of your software package. Be sure you use an appropriate title and axis labels. If you do not have access to the appropriate software, provide a rough sketch of the time plot that is given on the website.

(b) Is there a regular pattern of seasonal variation that repeats each year? Describe it. Are the prices increasing over time?

Please answer the following by hand showing all arithmatic and original formulas, please do not use a graphic calculator.

The province of Ontario is planning to construct a new hydropower plant to help make energy prices more affordable, as well as to support improved public health and environmental quality. The construction of the hydropower plant will start by the beginning of 2023 and will take 3 years at a cost of $200 million per year. The cost of maintenance and repairs, which is to start after project completion, is expected to be $5 million for the first 6 years, and to increase by $50,000 per year thereafter. The scrap value of the hydropower plant is estimated to be $25 million at the end of its service life. The project is expected to save the province $55 million per year in energy savings. Assume the present to be the end of 2017/beginning of 2018, the life of the project is till the end of year 2060, and the interest rate to be 5%.

A missionary couple, living in West Africa, bring their 4-year old son to the office of their physician on the second day of a visit home to Minnesota. The boy had a mild episode of diarrhea about seven days earlier and would not eat. He seemed to recover, but the mother noticed that the boy was having trouble walking the previous night and had seemed to have trouble dressing himself and walking that day.

On examination, the patient had no significant fever (98.9) and normal bowel sounds. His chest, ears and eyes were clear. He had no rebound tenderness in the abdomen. The physician noted that the child had poor muscular reflexes in his arms and legs. The child also was a bit lethargic and seemed confused.

The family lives in an isolated village in Africa. The mother opposes vaccinations on personal grounds, so the child has only had the initial series of DPT shots and no other typical vaccines. The village where they live has many problems with parasites and insect borne fevers (including Dengue).

Urine, stool and blood samples were collected for analysis.

1) This disease is most likely:

• an intestinal infection or parasite.
• a respiratory infection or parasite.
• a neurological infection or parasite.
• a urinary tract infection or parasite.
• Not enough information is given to determine this.

2) Your best guess at a diagnosis is:

• Hib meningitis
• sleeping sickness
• polio
• a parasitic worm
• malaria

3) Which of the following samples could easily provide confirmation of your diagnosis?

• The stool would show the presence of the worms.
• The serum would have antibody against polio.
• The urine would contain H. influenzae organisms.
• The blood would contain red blood cells with malarial parasites.
• Only CSF will show the answer.

4) Would receiving the childhood vaccine series have prevented this problem?

• yes, without doubt
• yes, most likely
• possibly, but living in Africa the pathogen load might be too high
• no, no vaccine is normally given
• no way, no vaccine exist

At an early stage of clinical trials of a certain method of gender​ selection, 14 couples using that method gave birth to 13 boys and 1 girl. Complete parts​ (a) through​ (e) below.
