The life expectancy for females in a certain country born during 1980−1985 was approximately 75.2 years. This grew to 76 years during 1985−1990 and to 76.2 years during 1990−1995. Construct a model for this data by finding a quadratic equation whose graph passes through the points ​(0,75.2​),​(5​,76​),and ​(10​,76.2​). Use this model to estimate the life expectancy for females born between 1995 and 2000 and for those born between 2000 and 2005.

Let x be the number of years since 1980 and y be the life expectancy for a person born between ​(1980+​x) and

​(1980+x+​5). Find a quadratic equation whose graph passes through the points ​(0,75.2​), ​(5​,76​), and ​(10​,76.2​).

Y=?

According to the model, the life expectancy of a female born between 1995 and 2000 in this country is ___?_ years.

According to the model, the life expectancy of a female born between 2000 and 2005 in this country is __?__ years.

Depreciation Methods

Clearcopy, a printing company, acquired a new press on January 1, 2019. The press cost $171,600 and had an expected life of 8 years or 4,500,000 pages and an expected residual value of $15,000. Clearcopy printed 691,900 pages in 2019. Do not round intermediate calculations. If required, round your answers to the nearest whole dollar.

Required:

1. Compute 2019 depreciation expense using the:

2. What is the book value of the machine at the end of 2019 under each method?

Write 3 detailed samples of scary text-based computer games. The location of your game could be a place that truly exists (possibly include research). Exclude graphic content. Remember to give choices to the player during the game.

Question 2

A study of the impact of graphical quality and age on time spent playing a computer game. Researchers record the time, in minutes, that children spent playing three computer games: one with minimal 2D graphics, one with high 2D graphic quality, and one with 3D graphic quality. Researchers also note the age group of each child: Under 10, 10 to 13, and over 13.

Write the null and alternative hypotheses for both factors and for their interaction.

Question 4

A study of the number of hits a video gets on YouTube based on the type of video (humorous, inspirational, musical, and informational) and on the length of the video (under 1 minute, 1 to 5 minutes, more than 5 but less than 10, 10 or more minutes).

Write the null and alternative hypotheses for both factors and for their interaction.

1. Massey Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $450,000 is estimated to result in $150,000 in annual pretax cost savings. The press falls in the MACRS five year class, and it will have a salvage value at the end of the project of $90,000. The press also requires an initial investment in spare parts inventory of $18,000, along with an additional $3,000 in inventory for each succeeding year of the project. If the shop’s tax rate is 35% and its discount rate is 14%, should Massey buy and install the machine press?

Blue Line machine shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $570,000 is estimated to result in $240,000 in annual pretax cost savings. The press falls in the MACRS five-year class and it will have a salvage value at the end of the project of $96,000. The press also requires an initial investment in spare parts inventory of $30,000, along with an additional $3,500 in inventory for each succeeding year of the project. The shop tax rate is 30 percent and the project's required return is 8 percent.
