S + l. = 34
11s + 21l= 514

-11s - 11l= -374
11s + 21l = 514

10l = 140

l = 20 long sleeve shirts

s + 20 = 34

s = 14 short sleet shirts

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below

Margaret [11]

Answer:

ALISSA

Step-by-step explanation:

Given the following scores :

NICO:

Score (x) = 81.6

Mean (m) = 72.6

Standard deviation (sd) = 15

EMILIO:

Score (x) = 225.3

Mean (m) = 205

Standard deviation (sd) = 29

ALISSA:

Score (x) = 8.08

Mean (m) = 7.2

Standard deviation (sd) = 0.4

STANDARDIZING THE DIFFERENT APTITUDE TEST SCORES:

OBTAINING THE ZSCORES :

Zscore = (x - mean) / standard deviation

NICO:

Zscore = (81.6 - 72.6) / 15

Zscore = 0.6

EMILIO:

Zscore = (225.3 - 205) / 29

Zscore = 0.7

ALISSA:

Zscore = (8.08 - 7.2) / 0.4

Zscore = 2.2

From the result of the Zscore, the best fit for the position is ALISSA

Write an equation of the line that passes through a pair of points:

vredina [299]

Answer:

b)

The equation of the line that passes through a pair of points

$y = \frac{-1}{8} ( x ) -\frac{11}{8}$

Step-by-step explanation:

Explanation:-

Given points are ( 5 ,-2) and ( 3,-1)

slope of the line

$m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{-1-(-2)}{-3-(5)} = \frac{1}{-8}$

The equation of the line that passes through a pair of points

$y - y_{1} = m ( x - x_{1} )$

$y - (-2) = \frac{-1}{8} ( x - (5) )$

$y = \frac{-1}{8} ( x ) +\frac{5}{8} -2$

$y = \frac{-1}{8} ( x ) +\frac{5-16}{8}$

$y = \frac{-1}{8} ( x ) -\frac{11}{8}$

Solve for the volume of the following figure.

Olenka [21]

Answer:

$96\pi \: or \: 301.59$

rounded to the nearest hundredth

Step-by-step explanation:

use the pythagorean theorem to find the height of the cone

${a}^{2} + {6}^{2} = {10}^{2}$

you get a = 8

the formula for the volume of a cone is

$\pi \:{r}^{2} \frac{h}{3}$

plug in 6 for the radius and 8 for the height. then solve

1b. b. At midnight the temperature is -7°C. At midday the temperature is 4°C. By how much did the temperature rise? * 1 point Yo

ElenaW [278]

Answer:

$Rise = 11^\circ C$

Step-by-step explanation:

Given

$Midnight \to -7^\circ C$

$Midday \to 4^\circ C$

Required

The temperature rise

This is the difference between the final and the initial temperature

$Rise = Midday - Midnight$

$Rise = 4^\circ C - -7^\circ C$

$Rise = 4^\circ C +7^\circ C$

$Rise = 11^\circ C$
