Modern vacuum pumps make it easy to attain pressures of the order of $10^{-13}$ atm in the laboratory. Consider a volume of air and treat the air as an ideal gas. (a) At a pressure of $9.00 \times 10^{-14}$ atm and an ordinary temperature of 300.0 K, how many molecules are present in a volume of $1.00 \mathrm{cm}^{3}$? (b) How many molecules would be present at the same temperature but at 1.00 atm instead?

Listed below are nine technical accounting terms used in this chapter:

$$\begin{array}{lll}\text { Unrecorded revenue } & \text { Adjusting entries } & \text { Accrued expenses } \\ \text { Book value } & \text { Matching principle } & \text { Accumulated depreciation } \\ \text { Unearned revenue } & \text { Materiality } & \text { Prepaid expenses }\end{array}$$

Each of the following statements may (or may not) describe one of these technical terms. For each statement, indicate the accounting term described, or answer "None" if the statement does not correctly describe any of the terms.

Do you see evidence of this admiration in Act One of the play? Would you say that Shakespeare himself admires Julius Caesar? Cite details from Act One to support your opinions.

How did the creation of the Fed improve our banking system?

Understanding the evolution of our banking system is important because it helps us understand the features of modern banking. Today we have a managed money supply that is accepted by everyone simply because people have faith in it. Which of the following is true about our banking system today?

c) Our banking system is shifting away from electronic bookkeeping.

The following situations describe decision scenarios that could use managerial accounting information:

1. The manager of High Times Restaurant wants to determine the price to charge for various lunch plates.
2. By evaluating the cost of leftover materials, the plant manager of a precision tool facility wants to determine how effectively the plant is being run.
3. The division controller of West Coast Supplies needs to determine the cost of products left in inventory.
4. The manager of the Maintenance Department of a large manufacturing company wants to plan next year's anticipated expenditures.

For each situation, discuss how managerial accounting information could be used.

Recall the table discussed before that gives the price of a gallon of regular gasoline in the United States (in dollars) for the years $2003$ through $2011$. Another table discussed gives the price of a gallon of regular gasoline in the United States (in dollars) for the years $1990$ through $2002$.

By using $1990$ as the base year, construct a simple index for the prices of a gallon of regular gasoline in both tables.

According to the Federal Bureau of Investigation, there is a violent crime in the United States every 22 seconds ( $A B C$ News, September 25, 2007). Assume that the time between successive violent crimes is exponentially distributed.

a. What is the probability that there is a violent crime in the United States in the next one minute?

b. If there has not been a violent crime in the previous minute, what is the probability that there will be a violent crime in the subsequent minute?

(a) Recall: What connections does Rodriguez draw between Addison's London and modern-day Tijuana?

(c) Speculate: Because of th e parallels Rodriguez notes between him self and Tijuana, do you think he can be objective in his presentation of the city? Why or why not?

In many of the world’s poorest countries, nearly 50 percent of the population is under 15 years of age. If these people are to help improve the productivity of their economies, they must be trained in modern methods of production. In 2000, just over 4 million of the 8.8 million people of Chad were under 15. Explain why it would be difficult for many of these children to be educated and become productive members of a growing economy.
