In 200 words explain.....Despite both theoretical and empirical evidence that a small amount of offenders commit the majority of crimes, three strikes legislation has failed at identifying and incarcerating this population. Based on your understanding of chronic offenders and the three strikes legislation, how would you alter this legislation to increase its effectiveness at reducing crime and targeting the chronic serious offender?

Sun Microsystems is a leading supplier of computer-related products, including servers, workstations, storage devices, and network switches. In 2009, Sun Microsystems was acquired by Oracle Corporation. In the letter to stockholders as part of the 2001 annual report, President and CEO Scott G. McNealy offered the following remarks: Fiscal 2001 was clearly a mixed bag for Sun, the industry, and the economy as a whole. Still, we finished with revenue growth of 16 percent—and that's significant. We believe it's a good indication that Sun continued to pull away from the pack and gain market share. For that, we owe a debt of gratitude to our employees worldwide, who aggressively brought costs down—even as they continued to bring exciting new products to market. The statement would not appear to be telling you enough. For example, McNealy says the year was a mixed bag with revenue growth of 16 percent. But what about earnings? You can delve further by examining the income statement in Exhibit 4. Also, for additional analysis of other factors, consolidated balance sheet(s) are presented in Exhibit 5.

Analyze your results to Question 2 (Part B above) more completely by computing ratios 1, 2a, 2b, and 3b (these

numbers correspond with the numbered ratios listing in Chapter 3 of our textbook) for 2000 and 2001. Actually,

the answer to ratio 1 can be found as part of the answer to question 2 (Part B), but it is helpful to look at it again.
