Here are the returns on two stocks.

a-1. Calculate the variance and standard deviation of each stock. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

a-2. Which stock is the riskier if held on its own?

• Digital Cheese

• Executive Fruit

b. Now calculate the returns in each month of a portfolio that invests an equal amount each month in the two stocks. (Negative amounts should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 2 decimal places.)

c. Is the standard deviation more or less than half way between the variance of the two individual stocks?

1. Construct a model that has a central carbon atom with four different colored spheres attached to it, representing four different atoms or groups. Fill in the line-and-wedge drawing below to represent this model and answer the following question: (a) Does the model have a plane of symmetry?

The central carbon atom is said to be a chirality center. Most molecules of nature are chiral. The word “chiral” is derived from the Greek word, cheir and means “handed.” Chiral molecules are related to their mirror images in the same way that your left hand is related to your right hand. They are not identical!

Change one of the colored spheres so that two of the four spheres are the same

(b) fill in a 3-D and answer the following questions:

c) Does the molecule now possess a plane of symmetry?

d) In view of your answers to a–b above, what condition is necessary for a molecule to be chiral?

2. Reconstruct the original carbon with four different colored spheres. Set the model on the table. Construct another model that is the mirror image of the first and place it on the table.

a) Try to superimpose the two models. Are they the same or different? If different, in what sense?

b) What is the stereochemical term that relates these two models?

c) What two important properties must the two molecules (models) each have to be related by the term that is the answer to 3b?

Choose one colored sphere on a model and remove it - Change it to match another color on that model. Do the exact same thing on the other model.
d) Are the models still mirror images?

e) Do the models have a plane of symmetry? If there is a plane of symmetry, describe its location.

f) Are the models superimposable?
g) Do the models represent identical or different molecules? Are they chiral? Explain.

Match each statemet with one of the following options

A: ... the same

B....the same

Select the correct statements in the following list.

A horizontal wire carries a current straight toward you. From your point of view, the magnetic field caused by this current circles the wire in a  counter-clockwise direction

The voltage across the terminals of a battery when a current flows is called the electromotive force.

If you connect two identical storage batteries together in parallel, and place them in a circuit, the combination will provide twice the voltage.

A charged particle moves across a constant magnetic field. The magnetic force on this particle causes the particle to accelerate.

You own five apartment complexes. You created a dataset listing the apartment numbers, apartment complex names, number of bedrooms, rental price, whether the apartment is occupied or not, and the date the apartment was last remodeled. You want to insert some functions to perform calculations to help you decide which apartments need to be remodeled. To focus on the apartments that need to be remodeled, you will use advanced filtering and database functions for your analysis. Finally, you are considering purchasing a sixth apartment complex. You will perform some financial calculations and analysis to help you decide if you will purchase the complex.

"A new delivery truck is available for $200,000. O&M costs are $21,000 each year for the first five years, $33,600 in year six, $52,100 in year seven, and $81,300 in year eight. Salvage values are estimated to be $150,000 after one year and will decrease at the rate of 17% per year thereafter. At a MARR of 17%, determine the economic service life of the truck. Enter your answer as an integer from 1 to 8."

Bill and Debra Jones

In this case you will be preparing – calculating financial reports and information in order to assess the Jones’s financial situation and needs.

First you need to see where they are right now.

Bill Jones 45, and Debra Jones 42 are married with two children ages 6 and 3.

Bill and Debra Jones   Case 1   Prepare and evaluate the Jones’s Statement of Financial Condition (Balance Sheet) and Statement of Cash Flows (Budget) in good presentation form.

Comment on their Financial Condition and their Budget

Klein Company distributes a high-quality bird feeder that sells for $30 per unit. Variable costs are $12 per unit, and fixed costs total $291,000 annually.

Required:

Answer the following independent questions:

1. What is the product’s CM ratio?

2. Use the CM ratio to determine the break-even point in sales dollars.

3. The company estimates that sales will increase by $67,000 during the coming year due to increased demand. By how much should operating income increase?

4. Assume that the operating results for last year were as follows:

a. Compute the degree of operating leverage at the current level of sales.

b. The president expects sales to increase by 16% next year. By how much should operating income increase?

5-a. Refer to the original data. Assume that the company sold 23,500 units last year. The sales manager is convinced that a 16% reduction in the selling price, combined with a $41,000 increase in advertising expenditures, would cause annual sales in units to increase by 40%. Prepare two contribution format income statements, one showing the results of last year’s operations and one showing what the results of operations would be if these changes were made. (Round "Per Unit" answers to 2 decimal places.)

5-b. Would you recommend that the company do as the sales manager suggests?

The current price of a non-dividend paying stock is $40. Use a two-step tree to value a European call option on the stock with a strike price of 42 that expires in 1 year. Each step is 6 months, the risk-free rate is 7% per annum with continuous compounding. What is the European call option price when u = 1.1 and d = 0.9 ?
