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? Make sure to defend your position by incorporating course material.

How to obtain the accumulated depreciate - Training equipment = $34,100?
How to balance the adjusted trail balance?
On 1 October, Hercules Ho sold a treadmill that costs $5,000,
with accumulated depreciation of $2,000 as at 31 Dec 2017 for cash
of $3,000. Hercules Ho deposited the cash into his personal bank
account. Hercules Ho forgot to inform his accountant of this
transaction. According to him, the cash taken by him was to be
treated as a loan to him.
Both the cost of the treadmill and the accumulated depreciation
were included in the amount shown for training equipment at cost
and the accumulated depreciation for training equipment in the
unadjusted trial balance above. The residual value of the treadmill
was originally estimated to be $500.
No depreciation has been charged for the year ended 31 Dec 2018.
During the year, no additional non-current assets was purchased.
The company depreciates non-current assets held at 31 Dec 2018 as
follows:
Training equipment at cost - straight line over five years. The
residual value of the training equipment at cost was estimated to
be $15,000.

Loretta, who turns eighty this year, has just learned about blood pressure problems in the elderly and is interested in how her blood pressure compares to those of her peers. Specifically, she is interested in her systolic blood pressure, which can be problematic among the elderly. She has uncovered an article in a scientific journal that reports that the mean systolic blood pressure measurement for women over seventy-five is 131.5mmHg, with a standard deviation of 5.7mmHg.
Assume that the article reported correct information. Complete the following statements about the distribution of systolic blood pressure measurements for women over seventy-five.

(a) According to Chebyshev's theorem, at least ?56%75%84%89% of the measurements lie between 117.25 mmHg and 145.75 mmHg. (b) According to Chebyshev's theorem, at least ?56%75%84%89% of the measurements lie between 120.1 mmHg and 142.9 mmHg. (c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately ?68%75%95%99.7% of the measurements lie between 120.1 mmHg and 142.9 mmHg. (d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 68% of the measurements lie between mmHg and mmHg. |

1) When import-competing sectors are exposed to heightened competition from abroad, what kinds of people are made worse off? (You may wish to distinguish people by age, gender, education, and minority status.) Who, if anyone, is made better off? In your answer, draw on the empirical findings discussed in class
2) China, India, and other emerging market economies are exporting increasingly sophisticated goods to the United States. (By sophisticated, ” I mean their production processes are capital-intensive and/or human capital-intensive.) Explain how this phenomenon might be interpreted using Lerner diagrams. In your answer, indicate whether you think this phenomenon spells doom for the U.S. manufacturing sector.
3) What does theory tell us about the effects of unskilled labor migration into a particular region? Specifically, discuss the intra-regional effects of this immigration on unskilled wages, product mix, and the returns to other factors (including, possibly, skilled labor, capital,and/or land). In your answer, contrast the predictions of the specific factors model with those of the Heckscher -Ohlin model, and state the assumptions you are invoking when discussing each. Finally, drawing on readings and class discussions, summarize the empirical evidence on these prediction
