Students who attend Anytown College pay either in-state or out-of-state tuition, depending on where they reside. The mean and st

netineya [11]

Answer:

For a pair of randomly selected in- and out-of-state students, the sum of their tuition typically varies from the mean of $6,348.75 by about $1,508.48.

Step-by-step explanation:

Given

$\mu S = \$6,348.75$

$\sigma S = \$1,508$

Required

Interpret the standard deviations

In statistic, standard deviation is a measure of how the given data lies away (or varies) from the mean.

This implies that:

For the in-state students, the standard deviation measures how the sum of their tuition varies from 6348.75

For the out-state students, the standard deviation measures how the sum of their tuition varies from 1508

cylinder with height 9 inches and radius is filled with water, it can fill a certain pitcher. How many of these pitchers can a c

larisa [96]

Answer:

Step-by-step explanation:

The 1st cylinder used to fill the pitcher has:

height:

h = 9 in

radius:

r = r

The volume of a cylinder is given by:

$V=\pi r^2 h$

Therefore, the volume of the 1st cylinder is

$V=\pi r^2 9=9\pi r^2$

We are told that the water inside this cylinder can fill a certain pitcher, so this is also the volume of the pitcher.

Then, we have a second cylinder, which has height

h = 9 in

and radius

r' = 2r

So the volume of this cylinder is

$V'=\pi r'^2 h = \pi (2r)^2 9 =9\pi (4r^2)=36\pi r^2$

This means that the number of pitchers that can be filled by this 2nd cylinder is

$n=\frac{V'}{V}=\frac{36\pi r^2}{9\pi r^2}=4$

The sum of 27 and -28 divided by 2.

hammer [34]

Hey there!

The word sum usually means addition in mathematics!

27 + (-28) / 2

= 27 - 28 / 2

= -1 / 2

= -0.5

Answer: -1/2 OR -0.5 (either those should work because they are both equivalent)

Good luck on your assignment and enjoy your day!

Determine the slope of the table A)2 B)5 C)-0.5 D)0.5

docker41 [41]

Answer:

C) -0.5

Step-by-step explanation:

Since the y₁ is decreasing, that automatically makes it a negative slope, and its decreasing by 0.5, so it's C!
