2. A. Explain in detail how the following can affect replacement decisions: i) taxes; ii) existing asset value; iii) economic life of the challenger and the defender; iv) technology

       B. You have $ 5 million dollars to invest in stocks. You have decided to do so in three

        firms. Following the example in class and in tabular form, divide the $ 5 million dollars

        among the three firms and calculate your expected return on your portfolio.

After you graduate from university, you find a job in a company that produces good X. You are working in a competitive market. Your boss asks you to compute the price elasticity of demand, income elasticity of demand, cross-price elasticity of demand, and the price elasticity of supply. The question is: how your boss will benefit from computing each of these elasticities. Explain in detail with an example for each case.

I need the answer minimum 500 words.

You want to determine the concentration of Fe2+in a solution. You decide to determine the Fe2+ concentration by means of a redox titration with potassium permanganate. You use 50 mL of the Fe2+ solution and adjust the pH to 1. You need 26.78 mL of a 0.0179 M KMnO4solution to reach the endpoint.

a. What is the reaction that takes place? Write the balanced chemical equation.

b. What is the concentration of Fe2+ in your original solution?

c. What is the balanced chemical equation for the titration of Fe2+with potassium dichromate? What volume of potassium dichromate (c=0.0148 M) would you have needed for this titration (the pH is acidic)?

d. Provide at least two methods to determine the endpoint of the titration with permanganate. Explain exactly how you would determine the endpoint. Do not just state the method

David Crystal's "Language and the internet" in chapter 1, What are Crystal's ideas about language and the internet? Explain in your own words!

Frolich came up with his dual center model of Food Intake. What did it state and how
did he come up with? Explain what likely happened using your understanding of
appetite and food seeking hormone control. Indicate how pathways were effected for
hunger and satiety in his animals.

12) Let x be a random variable that represents the pH of arterial plasma (i.e., acidity of the blood). For healthy adults, the mean of the x distribution is ? = 7.4 (Reference: The Merck Manual, a commonly used reference in medical schools and nursing programs). A new drug for arthritis has been developed. However, it is thought that this drug may change blood pH. A random sample of 31 patients with arthritis took the drug for 3 months. Blood tests showed that?̅ = 8.1 with a sample standard deviation ? = 1.9. Use a 5% level of significance to test the claim that the drug has changed (either way) the mean pH level of the blood.

a) What is the level of significance? State the null and alternative hypotheses.

b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution. Compute the appropriate sampling distribution of the sample test statistic.

c) Find (or estimate) the P-value.

d) Based on your answers in parts (a) through (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level ??

e) Interpret your conclusion in the context of the application.

Choose a global crime to discuss in detail. How and to what extent is globalization involved in perpetuating or reducing this criminal activity? What can be done to eradicate this crime and punish the criminals? Defend your answer.
