Answer:

5 - 1 year

6 - 738.92

Step-by-step explanation:

5:  260 = 250(1.04)^t

Divide both sides by 250, and we get 1.04. So t must be 1.

6:  x + 45 = x(1.03)²

Solve to find x

The equation h = 0.019s
TEA [102]

Answer:

s = 28.09 m/s

Step-by-step explanation:

Given that,

The equation that gives the height of the largest ocean waves when the wind speed is s knots is given by :

h=0.019s^2

We need to find the wind speed if the largest waves are 15 feet high.

Put h = 15 feet in the above equation as follows :

15=0.019s^2\\\\s^2=\dfrac{15}{0.019}\\\\s=28.09\ m/s

So, the speed of the wind is 28.09 m/s.

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.
