Among employees of a certain firm, 70% know C/C++, 60% know Java, and 90% know at least one of the two languages.

(a) What is the probability that a selected programmer knows both languages?

(b) What is the probability that a selected programmer knows C/C++ but not Java?

(c) What is the probability that a selected programmer knows only one of the two languages?

(d) If a programmer knows Java, what is the probability that he/she knows C/C++?

(e) If a programmer knows C/C++, what is the probability that he/she knows Java?

(f) Are the events “know Java” and “know C/C++” independent? Are then mutually exclusive? Explain.

Based on your knowledge on income elasticity of demand, normal good and inferior good, discuss the demand for luxury cars and bread (khubs) before February 2020 and after February 2020. Given today’s economic situation, would you advice the government to build more luxury car manufacturing plants or build green houses to produce food?

b)Just after S1 is closed, what is the potential differences Vbc?

c)A long time (many time constants) after S1 is closed, what is Vab?

d)A long time (many time constants) after S1 is closed, what is Vbc?

e)What is Vab at an intermediate time when i = 0.150A?

f)What is Vbc at an intermediate time when i = 0.150A?

There are various forms of collective violence. These include:

-War, terrorism, political conflicts

-Genocide, disappearances, torture, human rights abuses

-Organized violent crime (gangs, etc.)

In order to apply the sociological imagination to this problem, select one of the forms of collective violence and describe the consequences of that type of collective violence on the macro and micro levels. What might it be like to experience the type of collective violence you selected? Give specifics of how your current life would be affected by this type of violence. What global social problems might be perpetuated by this type of collective violence? Next, propose a possible solution to the global social problems you presented.

Capital budgeting

The Calpine firm is evaluating the purchase of a Theatre, the Dome. The Theatre would cost Calpine $1 mil­lion and would be depreciated for tax purposes using straight-line over 20 years (that is, $50,000 per year). It is expected that the Theatre will increase Calpine revenues by $400,000 per year, but would also increase expenses by $200,000 per year. Calpine would be expected to increase its working capital by $20,000 to accommodate the increased investment in ticket accounts receivable. Calpine firm intends to sell the Theatre to the city after ten years for $600,000. The marginal tax rate for Calpine is 35%. For purposes of identifying the tim­ing of cash flows, consider the purchase to be made at the end of 2010, the first year of operations the year 2011, and the last year of operations the year 2020.

1. What are the cash flows related to the acquisition of the Theatre?
2. What are the cash flows related to the disposition of the Theatre?
3. Calculate the net cash flows for each year, 2010 through 2020.
4. If the cost of capital for this project is 10%, should Calpine invest in the new Theatre?
5. Draw an investment profile of the project. Over what range of cost of capital would this project be attractive? Over what range of cost of capital would this project be unattractive?

JY investment Ltd holds a well-diversified portfolio of shares that has a market value of $1.5 million on 30 June 2019. JY is concerned about possible downturns in the share market and on 1 March 2020 decides to take out a sell position in eleven “September 2020 SPI 200 Futures” units when the SPI 200 is 5500. The SPI 200 Futures contract unit value is the value of SPI 200 multiplied by $25. To enter the contract, JY pays an initial cash deposit (margin) of $150,000 to a broker. On 30 June 2020, the reporting date of JY investment Ltd, the unit price of the September SPI futures contracts has fallen to 5300 and the market value of the firm’s portfolio of shares is $1 435 000. Assume broker allows a $50,000 drop before making a margin call to allow for minor fluctuations in the market. The shares are sold on 31 August 2020 when the market value of the shares is $1 290 000 and the September SPI 200 futures contract closed out at 5250 on 31 August 2020. Assume the futures contracts qualify as a hedge, the shares are marked to market.

REQUIRED: Prepare journal entries to account for the above events from 1 March 2020 to 31 August 2020. Show all calculations and round them to the nearest dollar amount. No narration is required.

An air-standard Carnot cycle is executed in a closed system between the temperature limits of 350 and 1200 K. The pressures before and after the isothermal compression are 150 and 300 kPa, respectively. If the net work output per cycle is 0.5 kJ, determine (a) the maximum pressure in the cycle, (b) the heat transfer to air, and (c) the mass of air. Assume variable specific heats for air.
