The correct answer is C

We are solving for C so we need to isolate C

Multiply 2 to both sides

2W = CV^2

Divide V^2

C = 2W/V^2

To compare the average amount of time that canadians and americans spend commuting, a researcher collects a sample of canadians

yKpoI14uk [10]

The standard error of the difference of sample means is 0.444

From the complete question, we have the following parameters

<u>Canadians</u>

Sample size = 50
Mean = 4.6
Standard deviation = 2.9

<u>Americans</u>

Sample size = 60
Mean = 5.2
Standard deviation = 1.3

The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.

This is represented as:

$SE = \frac{\sigma}{\sqrt n}$

The standard error of the Canadian sample is:

$SE_1 = \frac{2.9}{\sqrt{50}}$

So, we have:

$SE_1 = 0.41$

The standard error of the American sample is:

$SE_2 = \frac{1.3}{\sqrt{60}}$

So, we have:

$SE_2 = 0.17$

The standard error of the difference of sample means is then calculated as:

$SE= \sqrt{SE_1^2 + SE_2^2}$

This gives

$SE= \sqrt{0.41^2 + 0.17^2}$

$SE= \sqrt{0.197}$

Take square roots

$SE= 0.444$

Hence, the standard error of the difference of sample means is 0.444

For a reader to contrast two or more things, the reader must consider how they are.

kifflom [539]

Answer:

The correct answer is to compare.

For a reader to compare two or more things, the reader must consider how things are different.

Another option for the sentence could be to contrast. Compare or contrast are equally right,

A good reader needs to understand the different concepts contained in a text. If the reader does not understand the differences it would be difficult for it to have a clear idea and reach a valid conclusion. So, in order to do this, the reader has to compare ideas, propositions, theories or any other element that helps him recognize the differences.
