The probability of each state and the return of each stock in each state are presented in the table below. State Probability of state Return on Stock X Return on Stock Y Boom 20% 25% 35% Normal 80% 10% 5% What are the expected portfolio return and standard deviation?

Select one: a. 12% and 8.1% b. 12% and 9% c. 14.25% and 10.31% d. 14.25% and 9% e. 18.75% and 12.12%

1. Compound A is three times more soluble in diethyl ether than in water, so its partition coefficient is K = 3, for partitioning of compound A between diethyl ether and water. For a sample of compound A dissolved in 50 mL of water, answer the following questions:

A.) Determine the fraction of A that remains in the water, FsubA, after one extraction with 200 mL of diethyl ether.

B.) Determine FsubA after two extractions, using 100 mL of diethyl ether in each of the extractions.

C.) Determine FsubA after four extractionsm using 50 mL of deithyl ether in each of the extractions.

A brilliant young scientist is killed in a plane crash. It is anticipated that he could have earned $430,000 a year for the next 50 years. The attorney for the plaintiff’s estate argues that the lost income should be discounted back to the present at 4 percent. The lawyer for the defendant’s insurance company argues for a discount rate of 9 percent.
What is the difference between the present value of the settlement at 4 percent and 9 percent? Compute each one separately. Use Appendix D for an approximate answer but calculate your final answer using the formula and financial calculator methods. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

Using the attached template, you are to compute the gross pay, federal withholding, Social Security withholding, Medicare withholding and the net payment for this company. Assume there is no state income tax. Overtime is paid at a rate of 1.5 times the normal wage rate.

NOTE: PLEASE DONT FORGET THE PIVOT TABLE!

In addition, compute the total gross pay, federal withholding, Social Security withholding, Medicare withholding and net payment for all the employees. Further, create a pivot table indicating the total gross pay, Social Security withholding, Medicare withholding and net pay for wage employees and for salary employees. Please note you should use auto fill to complete this assignment in an efficient manner. Use the following Excel template:

Cane Company manufactures two products called Alpha and Beta that sell for $175 and $135, respectively. Each product uses only one type of raw material that costs $5 per pound. The company has the capacity to annually produce 117,000 units of each product. Its average cost per unit for each product at this level of activity are given below:

The company considers its traceable fixed manufacturing overhead to be avoidable, whereas its common fixed expenses are unavoidable and have been allocated to products based on sales dollars.

6. Assume that Cane normally produces and sells 101,000 Betas per year. What is the financial advantage (disadvantage) of discontinuing the Beta product line?

8. Assume that Cane normally produces and sells 71,000 Betas and 91,000 Alphas per year. If Cane discontinues the Beta product line, its sales representatives could increase sales of Alpha by 11,000 units. What is the financial advantage (disadvantage) of discontinuing the Beta product line?

9. Assume that Cane expects to produce and sell 91,000 Alphas during the current year. A supplier has offered to manufacture and deliver 91,000 Alphas to Cane for a price of $124 per unit. What is the financial advantage (disadvantage) of buying 91,000 units from the supplier instead of making those units?

10. Assume that Cane expects to produce and sell 61,000 Alphas during the current year. A supplier has offered to manufacture and deliver 61,000 Alphas to Cane for a price of $124 per unit. What is the financial advantage (disadvantage) of buying 61,000 units from the supplier instead of making those units?

Assume Haiti and Antigua are the only two countries that produce and consume fish and sugar. In a single year, Haiti can catch 50 tons of fish or produce 500 bags of sugar. In the same growing season, Antigua can catch 50 tons of fish or produce 750 bags of sugar. When the two countries begin trading fish for sugar, we expect the price of fish in Haiti:

A theater seating chart is implemented as a table of ticket prices, like this above Write a program that asks users to pick either a seat or a price. When choosing seat, indicate the row and column for the location; when choosing the price, like computer find the first available price; mark the sold seats by changing the price to 0. When a user specifies a seat, make sure it is available. Use loop to determine whether continue to order or not. In each time, the seating chart should be displayed for user. When user stops ordering, your program should output the number of tickets ordered, and amount ordered.

PS- the program is being written in python language and our insturctor has told us to us elif

1.

You will now need four files. These are telnos, telnos2, telnos3, telnos4. These files are all short files that contain names, departments, and telephone numbers. This is what they look like.

To make it easier to copy you can use the * (wildcard) to copy these files. Type in the command:

                cp /tmp/csc3321/telnos* .  

Remember the . (period) means current directory and will copy all of the telnos files at one time and assign them the names that they have in the instructor's file

In order to see how diff works, type in:

                diff telnos telnos2

What was the result?
________________________________________________________________________________________________________________________________________________________________________________________________________________________

The difference between these two files (telnos and telnos2) is that the 4th line in telnos is missing from telnos2. The first line that diff displays (4d3) indicates that you need to delete the 4th line from file telnos to make the two files match. The 4 is the line number and the (d) is delete. The line number to the left of each of the a,c, or d instructions always pertains to file1. Numbers to the right of the instructions apply to file2. The diff command assumes that you are going to change file1 to file2. The next line that diff displays starts with a less than (<) symbol indicating that this line of text is from file1. Next type in:

                diff telnos telnos3

What was the result?__________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

In this case, the second line has the (>) greater than sign which means that the extra line is in file2. The a means you must append a line to the file telnos after line 2 to make it match telnos3. Append means to add on to the end. Next is an example of the change feature. Type in the following command:

                diff telnos telnos4

What was the result? __________________________________________________________

What lines do you need to change in order to make the two files alike? ________________________________________________________________________________________________________________________________________________

Notice that the three hyphens indicate the end of the text in the first file that needs to be changed and the start of the second file that needs to be changed. Next, copy telnos to telnos5. What command did you use to do this? ________________________________________________________________________

Next, type in:

                diff telnos5 telnos2

What was the answer that you received? _________________________________________________________________________________________________________________________________________________________________________________________________________________

Use the vi editor to change telnos5 to match the file telnos2. Then check to see if they are now alike.

What command did you use? _________________________________________________________

What was the result? __________________________________________________

What is the output of the diff command when the files match?
_______________________________________________________________________________

When the two files are alike, there is no response. Unfortunately, Unix is not always user-friendly.

Uniq Command

The uniq command displays a file, removing all but one copy of successive repeated lines. If the file has been sorted, uniq ensures that no two lines that it displays are the same. Sort telnos and telnos3 and then send them to a new file called tel2. Type in the following:

                sort telnos telnos3 > tel2

Next look at the file, tel2. What does it contain?___________________________________________________________________________________________________________________________________________________________________________________________________

Next issue the command:

                uniq tel2

What was the result?__________________________________________________________________________________________________________________________________________________________________________________________________________________

The uniq command has three options. These are:

-c   Causes uniq to precede each line with the number of occurrences of the line in the input file

-d   Displays only lines that are repeated

-u   Displays only lines that are not repeated

Issue the command:

                uniq -u tel2

What was the result?__________________________________________________________________________________________________________________________________________________________________________________________________________________

Next, issue the command:

                uniq -d tel2

What was the result?__________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

You are studying the market value of home in Houston. You collect data from the recent sale of 30 single family homes. The data is organized and stored in an Excel file. The dataset includes the fair market value (in $thousands), land area of the property in acres, and age, in years of the 30 homes. Develop a multilinear regression model to predict the fair market value based on land area of the property (in acres) and age, in years.
