If there are 12 months (m) and he plans to watch 2 per month, we will just multiply 2(12) and it gets us with 24 movies. If the amount of months is lower than 12, we can just put 2(m)

James has a job with a current salary of $42,000. He wants to earn a college degree that will take him 2 years to complete and i
FinnZ [79.3K]

To recover the investment James will take \boxed{2.5{\text{ years}}}.

Further Explanation:

Given:

The current salary of James is \$ 42000.

The time taken to complete the college degree is 2{\text{ years}}.

The cost of the college degree is \$ 28000.

The James’ new salary after college degree will be \$ 56000.

Calculation:

The total investment of James can be calculated as follows,

\begin{aligned}{\text{Investment}} &= {\text{Salary of 2 years}} + {\text{2 years tuition fees}} \\&= 2 \times 42000 + 2 \times 28000\\&= 84000 + 56000\\&= \$ 140000\\\end{aligned}

The total investment for 2 years will be \$ 140000.

The James’ new salary after college degree will be \$ 56000.

The time taken by James to recover \$ 140000.

\begin{aligned}{\text{Time}} &= \frac{{140000}}{{56000}}\\&= 2.5{\text{ years}}\\\end{aligned}

To recover the investment James will take \boxed{2.5{\text{ years}}}.

A quality-assurance inspector periodically exam-ines the output of a machine to determine whether it is properly adjusted. When
Stolb23 [73]

Answer:

Step-by-step explanation:

From the given information;

The null hypothesis & alternative hypothesis:

\mathbf{H_o:\mu = 2}  \\ \\  \mathbf{H_1 : \mu \ne 2}

The test statistics can be computed as:

Z = \dfrac{\overline x - \mu}{\dfrac{\sigma}{\sqrt{n}}}

Z = \dfrac{2.025- 2}{\dfrac{0.07}{\sqrt{35}}}

Z = \dfrac{0.025}{\dfrac{0.07}{\sqrt{35}}}

Z =2.11

The p-value = 2(Z > 2.11)  since this is a two-tailed test

The p-value = 2( 1 - Z < 2.11)

The p-value = 2 (1 -0.9826)

The p-value = 2 (0.0174)

The p-value = 0.0348

Decision Rule: To reject the \mathbf{H_o}  if the p-value is less than \mathbf{H_o}

Conclusion: We fail to reject \mathbf{H_o} and conclude that the population mean = 2, thus the machine is properly adjusted.

Which equation is the same as “f of x equals the quantity one-fourth x plus nine all over ten”
