Answer:

D!!!!

Step-by-step explanation:

To find the percent mark up, find the amount of the mark up first:

From $ 21 , 450 → $ 27 , 950 is an increase of $ 6 , 500 To find the percent mark up:change original amount × 100 % 6500 21450 × 100 % = 30.3 % mark up in price.

A computer manufacturing company has sent a mail survey to 2,800 of its randomly selected customers that have purchased a new la

vodka [1.7K]

Answer:

The 96% confidence interval for the population proportion of customers satisfied with their new computer is (0.77, 0.83).

Step-by-step explanation:

We have to calculate a 96% confidence interval for the proportion.

We consider the sample size to be the customers that responded the survey (n=800), as we can not assume the answer for the ones that did not answer.

The sample proportion is p=0.8.

$p=X/n=640/800=0.8$

The standard error of the proportion is:

$\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.8*0.2}{800}}\\\\\\ \sigma_p=\sqrt{0.0002}=0.014$

The critical z-value for a 96% confidence interval is z=2.054.

The margin of error (MOE) can be calculated as:

$MOE=z\cdot \sigma_p=2.054 \cdot 0.014=0.03$

Then, the lower and upper bounds of the confidence interval are:

$LL=p-z \cdot \sigma_p = 0.8-0.03=0.77\\\\UL=p+z \cdot \sigma_p = 0.8+0.03=0.83$

The 96% confidence interval for the population proportion is (0.77, 0.83).

Write an equation in slope-intercept form of the line perpendicular to y = - 1 5 x + 1 4 that passes through the point (3, 4).

krok68 [10]

The equation of the line is $y=\frac{1}{15} x+\frac{19}{5}$

Explanation:

The equation is $y=-15x+14$ and passes through the point (3,4)

To find the equation of the line in slope intercept form, first we shall find the slope.

This equation is of the slope-intercept form $y=m x+b$ , we shall find the value of slope.

Thus, slope m = -15

Since, the line is perpendicular, the negative slope is given by $\frac{-1}{m}$

Thus, the new slope is $m=\frac{1}{15}$

Now, we shall find the equation of the line perpendicular to the slope $\frac{1}{15}$ is

$y-y_{1}=\frac{1}{15} \left(x-x_{1}\right)$

Let us substitute the points (3,4), we have,

$y-4=\frac{1}{15} \left(x-3\right)$

Muliplying the term within the bracket, we get,

$y-4=\frac{1}{15}x-\frac{1}{5}$

Adding both sides of the equation by 4, we get,

$y=\frac{1}{15}x-\frac{1}{5}+4$

Adding the like terms, we have,

$y=\frac{1}{15} x+\frac{19}{5}$

Thus, the equation in slope intercept form of the line is $y=\frac{1}{15} x+\frac{19}{5}$
