2. The following table shows that the economy next year has three possible states: Good , Average and Poor. It also shows the correponding probability of each states. The column of stock A shows the investment rate of return (%) for stock A; and the column of Stock B shows the invesment rate of return for stock B.

a) Calculate the expected value of stock A and B’s return (1 mark)

b) Calculate the variance of the return of Stock A and Stock B

c) Calculate the covariance and correlation of Stock A and Stock B’s return

d) An investor invests in 40% of his money in stock A and 60% of his money in stock B, what is his portfolio’s expected return? What is his portfolio’s variance and standard deviation?

Ms C. J. A patient on the medical-surgical unit, was adminitted 2 days before with a diagnoses of exacerbation of heart failure. this morning her blood pressure is 175/80 mm Hg. She denies chest pain but states that she has been experiencing shortness of breath at night while sleeping. her baseline weight at admission was 170 lb, but this morning's scale indicates a 4-lb weight gain, and +3 pitting edema to the lower extremities is evident. The nurse telephones the doctor and recieves an order for furosemide 40 mg by mouth twice daily and metopolol 25 mg PO daily to start immediately. 4. the nurse scans the medications in the electronic health record and medication administration record and administers the metoprolol. when she attempts to administers the furosemide, the patient states, " I don't want the water pill." what are the nurse next action?

Case Study: The Patient with Endocrine Problems

The nurse is caring for a 41-year-old woman who is the mother of two small children. She states that she has felt “nervous and tired” for approximately 1 month. Today, she has had a sudden onset of breathlessness with cardiac palpitations. She states, “I have not been feeling well for about a month, but when I felt breathless I thought I should be checked out.” Upon further questioning, the nurse finds that the woman also has had an unexplained loss of weight of approximately 30 lbs over 3 months, frequent loose stools, loss of hair on the scalp, and a feeling of “burning up.”

If surgical intervention is necessary, what preoperative care would the nurse anticipate?

If surgical intervention is employed what surgery would be preferred? Identify the appropriate postoperative care for this patient.

Introduction: Assume that you have the following hypothetical data. Use the data to complete the following requirements. Dataset: Lab 4.sav Requirements: Question 1: Generate the descriptive statistics and perform an appropriate statistical analysis to determine whether state median household income is related with fatality rate across states. a. Report and interpret your statistical results, as well as create tables/figures in accordance with the APA guideline for the professional audience. b. Also, briefly address the results and their impacts written for a lay audience. Question 2: Investigate whether state median household income predicts fatality rate across states. a. Report and interpret your statistical results, as well as create tables/figures in accordance with the APA guideline for the professional audience. b. Also, briefly address the results and their impacts written for a lay audience

1. Write a balanced equation describing each of the following chemical reactions. (Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)

(a) When solid potassium chloride is added to aqueous sulfuric acid, hydrogen chloride gas and aqueous potassium sulfate are produced.

(b) Aqueous solutions of phosphoric acid and rubidium hydroxide react to produce aqueous rubidium dihydrogen phosphate and liquid water.

2. Four moles of hydrogen iodide (HI) gas react with one mole of oxygen (O₂) gas to produce two moles of iodine gas (I₂) and two moles of water gas (H₂O). Using this description of the reaction, write the corresponding chemical equation, showing the appropriate coefficients for each reactant and product. (Include states-of-matter under the given conditions in your answer.)

Say you are presented with two beakers, beaker A and beaker B, each containing a white, powdery compound.

a. From your initial observations, you suspect that the two beakers contain the same compound. Describe, in general terms, some experiments in a laboratory that you could do to help prove or disprove that the beakers contain the same compound.

b. Would it be easier to prove that the compounds are the same or to prove that they different? Explain your reasoning.

c. Which of the experiments that you listed above are the most convincing in determining whether the compounds are the same? Justify your answer.

d. A friend states that the best experiment for determining whether the compounds are the same is to see if they both dissolve in water. He proceeds to take 10.0 g of each compound and places them in separate beakers, each containing 100 mL of water. Both compounds completely dissolve. He then states,

Design a synchronous counter having the count sequence given by the following table. Use negative edge-triggered T flip-flops provided with a clock. (i) Draw the state diagram of the counter. (ii) Build the counter's state table showing the synchronous inputs of the T flip-flops as well. (iii) Using Karnaugh maps, find the minimal sum-of-products form of the equations for the inputs to the flip-flops; assume the next states of the unused combinations to be "don't care states" (iv) Draw the logic diagram of the counter

In a well thought out argument provide a clear and detail response to the question below: Mark sure your response meets the expectation per the syllabus in order to get full credit.

Why do you think so many city governments and states seem to "bend over backwards" to get new businesses to locate in their local economies? Indeed, many cities, counties and states offer tax breaks (e.g. promises not to impose local property taxes for up to 15 years), and some provide land free to businesses who choose to locate in their areas.

1) What concept introduced in this chapter could help explain this behavior?

2) Provide examples from your local city where these incentives have been provided. Do you also feel it was a benefit or detriment to the towns economy?
