Use online resources to work on this chapter's questions. Please note that website information changes over time, and these changes may limit your ability to answer some of these questions. In this chapter, we described how to estimate a company's WACC, which is the weighted average of its costs of debt, preferred stock, and common equity. Most of the data we need to do this can be found from various data sources on the Internet. Here we walk through the steps used to calculate Minnesota Mining & Manufacturing's (MMM) WACC.

a. What is your estimate of MMM's WACC using the book-value weights calculated in question 1a?

b. What is your estimate of MMM's WACC using the market-value weights calculated in question 1b ?

c. Explain the difference between the two WACC estimates. Which estimate do you prefer? Explain your answer.

d. How confident are you in the estimate chosen in part c? Explain your answer.

Many variables have an effect on choosing the price of a house. A few of these are the size of the house (square feet), lot size, and the number of bathrooms. Information for a random sample of homes for sale in the Statesboro, Georgia, area was obtained from the Internet. Regression output modeling the asking price with square footage and the number of bathrooms gave the next result.

Dependent Variable is: Asking Price

Recent balance sheets of Dell, Inc., a leading producer and marketer of a broad range of personal computers, mobility products, software, and related tools and services, are provided in the internet.

Required:

1. Is Dell a corporation, sole proprietorship, or partnership? Explain the basis of your answer.

2. Use the company’s balance sheet (consolidated statement of financial position) to determine the amounts in the accounting equation (A = L + SE) at the end of the most recent year.

3. Calculate the company’s current ratio on January 30, 2009. Interpret the ratio that you calculated. What other information would make your interpretation more useful?

4. Give the journal entry the company will make in 2009 when it pays its fiscal year 2008 accounts payable (fiscal year 2008 ends on January 30, 2009).

5. Does the company appear to have been profitable over its years in business? On what account are you basing your answer? Assuming no dividends were paid, how much was net income (or net loss) in the most recent year? If it is impossible to determine without an income statement, state so.

Jason would like to know the typical cost of advertised Pandas. What kind of a graphical display should he use? b. What type of graph should be used to display the relationship between age and cost? c. Make a scatterplot of the data. d. Fully describe the association. e. Draw a line of best fit for the data. Find the equation of the line of best fit. f. Use the equation to predict the expected cost of a 6-year-old car. g. Interpret the slope and y-intercept in context.

For the VoIP example in earlier Section , we introduced an online procedure (exponential moving average) for estimating delay. In this problem we will examine an alternative procedure. Let t$_i$ be the timestamp of the $_i$th packet received; let r$_i$ be the time at which the $_i$th packet is received. Let d$_n$ be our estimate of average delay after receiving the nth packet. After the first packet is received, we set the delay estimate equal to d$_1$ = r$_1$ – t$_1$ .

a. Suppose that we would like d$_n$ = (r$_1$ – t$_1$ + r$_2$ – t$_2$ + . . . + r$_n$ – t$_n$)/n for all n. Give a recursive formula for d$_n$ in terms of d$_n–1$, r$_n$, and t$_n$.

b. Describe why for Internet telephony, the delay estimate described in earlier Section is more appropriate than the delay estimate outlined in Part a.

In 2006, an ex-KGB agent was murdered in London. Subsequent investigation showed that the cause of death was poisoning with the radioactive isotope ${ }^{210} \mathrm{Po}$, which was added to his drinks/food.
(a) ${ }^{210} \mathrm{Po}$ is prepared by bombarding ${ }^{209} \mathrm{Bi}$ with neutrons. Write an equation for the reaction.
(b) Who discovered the element polonium? (Hint: See an Internet source such as Webelements.com.)
(c) The half-life of ${ }^{210} \mathrm{Po}$ is $138 \mathrm{~d}$. It decays with the emission of an $\alpha$ particle. Write an equation for the decay process.
(d) Calculate the energy of an emitted $\alpha$ particle. Assume both the parent and daughter nuclei to have zero kinetic energy. The atomic masses are ${ }^{210} \mathrm{Po}(209.98285 \mathrm{amu})$, ${ }^{206} \mathrm{~Pb}(205.97444 \mathrm{amu}),{ }_2^4 \alpha(4.00150 \mathrm{amu})$.
(e) Ingestion of $1 \mu \mathrm{g}$ of ${ }^{210} \mathrm{Po}$ could prove fatal. What is the total energy released by this quantity of ${ }^{210} \mathrm{Po}$ ?

Lee los versos del poema "Queda prohibido" y haz la activadad a continucion. Queda prohibido no sonreir a los problemas, no luchar por lo que quiero, abandonarlo todo por tener miedo, no convertir en realidad mis sueños. Queda prohibido no ser yo ante la gente, fingir ante las personas que no me importan, hacerme el gracioso con tal de que me recuerden, olvidar a toda la gente que me quiere. Finalmente, escribe un párrafo en el que expliques la relación entre lo que dice el poeta y la autoestima. Incluye tu opinión acerca de las ideas del poeta sobre el tema. Si te interesa leer todo el poema, búscalo en Internet o pídele una copia a tu profesor(a).

Many variables have an impact on determining the price of a house. Among these are Living Area of the house (square feet) and number of Bathrooms. Information for a random sample of homes for sale in the Statesboro, GA, area was obtained from the Internet. Regression output modeling the asking Price with Living Area and number of Bathrooms gave the following result:

$$\begin{array}{l} \begin{array}{l} \text{Dependent Variable is: Price}\\ \text{s = 67013 \quad R-Sq = 71.1\\\%} \end{array} \\ \begin{array}{lr} \text{Predictor} & \text{Coeff}\\ \text{Intercept} & -152037\\ \text{Bathrooms} & 9530\\ \text{LivingArea} & 139.87 \end{array} \end{array}$$

The owner of a construction firm, upon seeing this model, says that the slope for bathrooms is too small. He says that when he adds another bathroom, it increases the value by more than $9530. Can you think of an explanation for his question?

Charles Schwab Corporation is one of the more innovative brokerage and financial service companies in the United States. The company recently provided information about its major business segments as follows (in millions):

b. Provide a specific example of a variable and fixed cost in the Investor Services segment.

c. Estimate the contribution margin for each segment, assuming that depreciation represents the majority of fixed costs.

d. If Schwab decided to sell its Advisor Services business to another company, estimate how much operating income would decline.
