Answer:

The p-value of the test is 0.0416 < 0.05, which means that the null hypothesis is rejected.

Step-by-step explanation:

The engineer designed the valve such that it would produce a mean pressure of 5.7 pounds/square inch. It is believed that the valve performs above the specifications.

At the null hypothesis, we test that the mean is the specification value of 5.7, that is:

[tex]H_0: \mu = 5.7[/tex]

At the alternate hypothesis, we test that the mean is above the specifications, that is, above 5.7. So:

[tex]H_a: \mu > 5.7[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

5.7 is tested at the null hypothesis:

This means that [tex]\mu = 5.7[/tex]

The valve was tested on 8 engines and the mean pressure was 6.2 pounds/square inch with a variance of 0.49.

This means that [tex]n = 8, X = 6.2, s = \sqrt{0.49} = 0.7[/tex]

Test statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{6.2 - 5.7}{\frac{0.7}{\sqrt{8}}}[/tex]

[tex]t = 2.02[/tex]

P-value of the test and decision:

The p-value of the test is the probability of finding a sample mean above 6.2, which is the p-value of t = 2.02, using a right-tailed test with 8 - 1 = 7 degrees of freedom.

With the help of a calculator, this p-value is 0.0416.

The p-value of the test is 0.0416 < 0.05, which means that the null hypothesis is rejected.

Answer:

The value of [tex]y[/tex] when the value of [tex]x[/tex] is multiplied by [tex]\frac{1}{2}[/tex] is [tex]\frac{5}{8}[/tex].

Step-by-step explanation:

According to the statement, we have the following relationship:

[tex]y = k\cdot x^{3}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]k[/tex] - Proportionality constant.

We can eliminate the proportionality constant by constructing the following relationship:

[tex]\frac{y_{2}}{y_{1}} = \left(\frac{x_{2}}{x_{1}} \right)^{3}[/tex]

If we know that [tex]y_{1} = y[/tex], [tex]y_{2} = 5[/tex], [tex]x_{2} = x_{o}[/tex] and [tex]x_{1} = \frac{1}{2}\cdot x_{o}[/tex], then the value of [tex]y[/tex] when the value of [tex]x[/tex] is multiplied by [tex]\frac{1}{2}[/tex] is:

[tex]\frac{5}{y} = \left(\frac{x_{o}}{\frac{1}{2}\cdot x_{o} } \right)^{3}[/tex]

[tex]\frac{5}{y} = 8[/tex]

[tex]y = \frac{5}{8}[/tex]

The value of [tex]y[/tex] when the value of [tex]x[/tex] is multiplied by [tex]\frac{1}{2}[/tex] is [tex]\frac{5}{8}[/tex].

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

A carpenter is building a rectangular deck. The deck should have a width, f(x), to length, g(x), and a ratio of 2 to 3. The area of the deck is represented by the function h(x).

The functions are given below.

f(x) = 2x

g(x) = 3x

h(x) = f(x) × g(x) = 6x²

[tex]a=55.83[/tex] yds

[tex]c=100[/tex] yds

[tex]h=52[/tex] yds

To find:

The area of the parallelogram.

Solution:

The area of a parallelogram is:

[tex]A=base\times height[/tex]

In the given parallelogram, the base is [tex]c=100[/tex] yds and the height is [tex]h=52[/tex] yds. So, the area of the parallelogram is:

[tex]A=100\times 52[/tex]

Answer:

The nth term is 27 - 30(n-1) or can be simplified to 57 - 30n.

Step-by-step explanation:

This is an arithmetic sequence (ie. each term equals the previous term with a constant value added (or subtracted from it)

T1 = 27

T2 = -3 = T1 - 30 = 27 - 30

T3 = -33 = T2 -30 = 27 -30 - 30=27-30X(2)

T4= -63 = T3 - 30 =27-30X(2)-30=27-30X(3)

In general, the nth term of this sequence:
