denpristay [2]

Correct question is;

You represent a chemical company that is being sued for paint damage to automobiles. You want to support the claim that the mean repair cost per automobile is more than $650. How would you write the null and alternative hypotheses?

A) State the null and alternative hypotheses in words (context of the problem)

B) Write the null and alternative hypotheses in appropriate symbols (population parameters μ, σ or p)

C) Describe in words Type I error (the consequence of rejecting a true null hypothesis.)

D) Describe in words Type II error (the consequence of failing to reject a false null hypothesis.)

Answer:

A)In words;

Null hypothesis is that the cost is $650

Alternative hypothesis is that the cost is not $650

B) Null hypothesis; μ = 650

Alternative hypothesis; μ ≠ 650

C) Type I Error will be to make a claim that the repair cost is not $650, when it is actually $650.

D) Type II Error will be to make a claim that the repair cost is not $650, but fail to reject the claim that it is $650.

Step-by-step explanation:

We are told that You want to support the claim that the mean repair cost per automobile is more than $650.

Thus;

A)In words;

Null hypothesis is that the cost is $650

Alternative hypothesis is that the cost is not $650

B) Null hypothesis; μ = 650

Alternative hypothesis; μ ≠ 650

C) Type I Error will be to make a claim that the repair cost is not $650, when it is actually $650.

D) Type II Error will be to make a claim that the repair cost is not $650, but fail to reject the claim that it is $650.

A(5 1) b(1 5) and c(-3 -1) are the vertices of triangle abc. find the LENGTH of median ad
faltersainse [42]

Answer:

\text{Length of median AD}=\sqrt{37}

Step-by-step explanation:

We are given the vertices of triangle ABC. We need to find the length of median AD.

Please see the attachment for figure.

D is mid point of BC because median bisect the opposite side of triangle.

Using the formula of mid point. we get coodrinate of D

\text{Mid Point :}\left ( \frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right )

D is mid point of B(1,5) and C(-3,-1)

\therefore D \left ( \frac{1-3}{2},\frac{5-1}{2} \right )\Rightarrow (-1,2)

AD is median of triangle ABC. Now we find length of median AD using distance formula of two coordinate.

\text{Distance }=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

A(5,1) and D(-1,2)

AD=\sqrt{(5+1)^2+(1-2)^2}\Rightarrow \sqrt{36+1}

\text{Length of median AD}=\sqrt{37}

Thus, \text{Length of median AD}=\sqrt{37}

Answer:

A)  Function Rule: <u> y = x+3</u>

<u />

Substitution:

y = 2 + 3

y = 3 + 3

y = 4 + 3

y = 5 + 3

B) Function Rule: <u> y = 5x</u>

<u />

Substitution:

y = 5 * 2

y = 5 * 3

y = 5 * 5

y = 5 * 6

C) Function Rule: <u> y = x + (x - 1)</u>

<u />

Substitution:

y =  2 + (2 - 1)

y = 3 + (3 - 1)

y = 4 + (4 - 1)

y = 5 + (5-1)

Hope this helps! Tell me if you have any more questions!
