a) 5.82%

b) 44.81%

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

(a) What percent of all applicants had scores higher than 13?

All applicants have $\mu = 9.7, \sigma = 2.1$

This probability is 1 subtracted by the pvalue of Z when X = 13. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{13 - 9.7}{2.1}$

$Z = 1.57$

$Z = 1.57$ has a pvalue of 0.9418

1 - 0.9418 = 0.0582

5.82% is the answer

(b) What percent of those who entered medical school had scores between 9 and 11?

Those who entered medical school have $\mu = 10.5, \sigma = 1.6$ .

This probability is the pvalue of Z when X = 11 subtracted by the pvalue of Z when X = 9. So

X = 11

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{11 - 10.5}{1.6}$

$Z = 0.31$

$Z = 0.31$ has a pvalue of 0.6217

X = 9

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{9 - 10.5}{1.6}$

$Z = -0.94$

$Z = -0.94$ has a pvalue of 0.1736

0.6217 - 0.1736 = 0.4481 = 44.81%

Write the equation of the line fully simplified slope-intercept form. 1 2 3 4 5 6 7 8 9 10 11 12 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10

Jlenok [28]

Answer:

$y = -x$

Step-by-step explanation:

Given

$x: 1\ \ ||\ 2\ \ \ ||\ \ \ 3\ ||\ \ 4\ ||\ \ \ 5\ ||\ \ \ 6\ ||\ \ 7\ ||\ \ \ 8\ ||\ 9\ \ \ ||\ \ 10\ ||\ \ \ 11\ ||\ 12\\ y: -1 || -2|| -3 || -4 || -5 || -6|| -7 || -8 || -9 || -10 || -11 || -12$

Required

Write the equation of the line;

Start by picking any two corresponding x and y values

$(x_1,y_1) = (1,-1)$

$(x_2,y_2) = (12,-12)$

Next, determine the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{-12 - (-1)}{12 - 1}$

$m = \frac{-12 +1}{11}$

$m = \frac{-11}{11}$

$m = -1$

The equation is then calculated using:

$y - y_1 = m(x - x_1)$

$y - (-1) = -1(x - 1)$

$y + 1 = -x +1$

$y = -x$

Hence, the line equation is:

$y = -x$

Can Someone Simplify this <br> 2 ( 3 X - 4 ) + ( X + 11 ) + 5

alexandr402 [8]

First, distribute 2 through the parentheses.
Then, take out the parentheses of (x+11)

6x-8+x+11+5

Now collect the like terms.

6x+x=7x
-8+11+5=+8

So the answer is: 7x+8
