Consider historical data showing that the average annual rate of return on the S&P 500 portfolio over the past 85 years has averaged roughly 8% more than the Treasury bill return and that the S&P 500 standard deviation has been about 29% per year. Assume these values are representative of investors' expectations for future performance and that the current T-bill rate is 4%.

Calculate the utility levels of each portfolio for an investor with A = 3. Assume the utility function is U = E(r) − 0.5 × Aσ². (Negative amounts should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 4 decimal places.)

Robert hires workers to pack the Haskap berries he is growing. The market for Haskap berries is perfectly competitive, and the price of Haskap berries is $2 per bucket. The labour market is competitive, and the market wage rate is $16/hour. Table 1.0 below shows the workers’ total product schedule # of workers # buckets of Haskap berries produced per hour 1 14 2 26 3 36 4 44 5 50 Table 1.0 Answer the following: 1. What is the marginal product of the third worker hired, and what is that worker’s Value of Marginal Product? 2. How many workers will Robert hire to maximize profit and what will the workers produce? 3. If the market wage rate rises to $20/hour, how many workers will Robert hire?

Part A. Calculate the pH of a buffer solution that is 0.250 M in HCN and 0.168 M in KCN. For HCN, Ka = 4.9×10⁻¹⁰ (pKa = 9.31).

Part B. Calculate the pH of a buffer solution that is 0.240 M in HC2H3O2 and 0.190 M in NaC2H3O2. (Ka for HC2H3O2 is 1.8×10−5.)

Part C. Consider a buffer solution that is 0.50 M in NH3 and 0.20 M in NH4Cl. For ammonia, pKb=4.75. Calculate the pH of 1.0 L of the original buffer, upon addition of 0.150 mol of solid NaOH.

Part D. A 1.0-L buffer solution contains 0.100 mol HC2H3O2 and 0.100 mol NaC2H3O2. The value of Ka for HC2H3O2 is 1.8×10−5. Calculate the pH of the solution, upon addition of 0.055 mol of NaOH to the original buffer.

Write a method named area with one double parameter name radius. The method needs to return a double value that represents the area of a circle. If the parameter radius is negative , then return -1.0 to present an invalid value

Write another overload method with 2 parameters side1 and side2 (both double) where side1 and side2 represent the sides of a rectangle. The method needs to return an area of a rectangle . If either or both parameters is/ are negative return -1.0 indicate an invalid value.

Example output:

area(5.0) should return 78.53975

area(-1) should return -1 since the parameter is nagative

area(5.0, 6.0) should return 30.0 (5 * 6 = 30)

All method need to be defined as public static

Add a main method to your solution code
