Answer:

The answer to your question is Perimeter = 26 units

Step-by-step explanation:

Data

Vertex

A(-2, 3)

B (4, 7)

C (7, -1)

Process

1.- Find the distance between the vertex

dAB = \sqrt{(4 + 2)^{2} + (7-3)^{2}}

dAB = \sqrt{6^{2}+ 4^{2}}

dAB = \sqrt{36 + 16}

dAB = \sqrt{52}

dBC = \sqrt{(7-4)^{2} + (-1 -7)^{2}}

dBC = \sqrt{3^{2} + 8^{2}}

dBC = \sqrt{9 + 64}

dBC = \sqrt{73}

dAC = \sqrt{(7 + 2)^{2}+ (-1-3)^{2}}

dAC = \sqrt{9^{2} + 4^{2}}

dAC = \sqrt{81 + 16}

dAC = \sqrt{97}

Perimeter = \sqrt{52} + \sqrt{73} + \sqrt{97}

Perimeter = 7.21 + 8.54 + 9.84

Perimeter = 25.59 ≈ 26 units

Hello!

To find the area of a rectangular prism you do 2(lw + lh + wh)

Put in the values

2(9 * 2 + 9 * 6 + 2 * 6)

2(18 + 54 + 12)

2(84)

2 * 84 = 168

The answer is 168 cubic inches

Answer:

The 95% confidence interval for the average number of years until the first major repair is (3.1, 3.5).

Step-by-step explanation:

The (1 - <em>α</em>)% confidence interval for the average using the finite correction factor is:

CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\cdot\sqrt{\frac{N-n}{N-1}}

The information provided is:

N=1500\\n=183\\\sigma=1.47\\\bar x=3.3

The critical value of <em>z</em> for 95% confidence level is,

<em>z</em> = 1.96

Compute the 95% confidence interval for the average number of years until the first major repair as follows:

CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\cdot\sqrt{\frac{N-n}{N-1}}

     =3.3\pm 1.96\times\frac{1.47}{\sqrt{183}}\times\sqrt{\frac{1500-183}{1500-1}}\\\\=3.3\pm 0.19964\\\\=(3.10036, 3.49964)\\\\\approx (3.1, 3.5)

Thus, the 95% confidence interval for the average number of years until the first major repair is (3.1, 3.5).
