- An oil and gas exploration firm invested $2,000,000 in drilling for natural gas in a new gas field. The firm's geologist believes the field has the potential to produce gas for many years. The revenue resulting from the gas well the first year after drilling is $600,000; based on previous experiences with similar types of wells, it is expected the annual revenue will decrease at an annual rate of 3%. Likewise, the costs of operating the well the first year totals $100,000; costs are expected to increase at an annual rate of 7%. If the firm's MARR is 17%, how long will it take for the firm to recover its investment? Hint: Using Excel's Goal Seek or SOLVER tool leave cell for the number of years required to recover the investment empty.

Years of Potential Life Lost (YPLL) can be defined as the number of years lost when death occurs before one’s life expectancy. For this assignment, life expectancy will be set for everyone at 75. For YPLL, a death of a very young person is weighted more than a death of a very old person (McKenzie, Pinger, & Seabert, 2018). AS Instructions: Investigate one cause of death (infant mortality, homicide, suicide, unintentional injuries (such as car accidents, drowning, falling, etc.), pregnancy complications, COVID-19, etc.) in the United States and research the YPLL for racial/ethnic groups and genders. Summarize your findings in your paper and discuss how calculating YPLL can change the way we think about that particular cause of death differently.

- A personnel director wishes to compare the effectiveness of two methods of train- ing industrial employees to perform a certain assembly operation. Employees are to be divided into two equal groups: the first receiving training method 1 and the sec- ond training method 2. Each will perform the assembly operation, and the length of assembly time will be recorded. It is expected that the assembly times for both groups will have a range of approximately 8 minutes. For the estimate of the difference in mean times to assemble to be correct to within minute with a probability equal to .95, how many workers must be included in each training group? 16c3d JPG Fi DOFirst, you need to design, code in Java, test and document a base class, Student.
