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).

The answer is Option B $(x + 6)(x^2 + 8)$

Step-by-step explanation:

Step 1: Group the given cubic polynomial into two sections.

So polynomial can be grouped as

$(x^3 + 6x^2) + (8x + 48)$

Step 2:Find what's the common in each section.

In section $(x^3 + 6x^2)$ the come term is $x^2$

In section (8x + 48) the come term is 8

Step 3:Factor the commonalities out of the two terms.

Factoring out $x^2$ from the first section $(x^3 + 6x^2)$ , we get $x^2(x + 6)$

Factoring out 8 from the second section(8x + 48) , we will get 8(x + 6).

Step 4: Combine the factors together for terms contains the same factor,

Combining we get, $\left(x+6\right)\left(x^2+8\right)$

$\left(x+6\right)\left(x^2+8\right)$
