Answer:
The correct option is D) reduce test scores by 4.56 for every school district.
Explanation:
Based on the information in the question, the relationship between test scores and the student-teacher ratio can be mathematically written as follows:
x = 698.9 - 2.28y .................... (1)
Where,
x = test scores
y = student-teacher ratio
The a slope of (-2.28) indicates the amount by which x will change whenever there is a change in y.
Therefore, when there is a decrease in the student teacher ratio by 2 (i.e. y = 2), we will have:
Change in x = -2.28 * 2 = -4.56
The negative sign therefore indicate that the test scores will reduce by 4.56 for every school district. Therefore, the correct option is D) reduce test scores by 4.56 for every school district.

Answer:a. The company will be $11,000 better off over the 5 year period if it replaces the old machine.
Explanation:
The purchase of the new machine will bring the annual operating expenses to $9,000 compared to the $15,000 been spent on the old machine which brings in a savings of $6000 and when this is added to the $ 5000 increase sales revenue from the new machine, it means the company will be better off by $11,000 over the next five year if it replaces the old machine.
There is no justification for being $12,000, $20,000 or $6000 better off over the next five year by either replacing or keeping the old machine.
