Pachacha [2.7K]

'According to the declaration, whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it.

And then they must establish a new government, based on such principles and organizing its powers in such a way that it appears most likely to effect their safety and happiness.

Prudence, indeed, will dictate that long-established governments should not be changed for trivial and transitory reasons; and all experience has shown that mankind are more inclined to suffer while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed.

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

Given the function f(x) = 3(x – 2)2 + 4 with a restricted domain of x ≥ 2, which of the following represents f–1(x)?.

Debora [2.8K]

The inverse of the function is $f^{-1}x= \sqrt{\frac{x-4}{3} } + 2$

<h3 /><h3>Domain and Range of functions</h3>

Given the function

$f(x) = 3(x - 2)^2 + 4$

To get the inverse, you will follow the same step as shown:

Rewrite the equation to have:

$y= 3(x - 2)^2 + 4$

Replace x with y

$x = 3(y - 2)^2 + 4$

<h3>Make y the subject of the formula</h3>

$x = 3(y - 2)^2 + 4\\x-4=3(y - 2)^2\\\frac{x-4}{3} = (y-2)^2\\ y-2=\sqrt{\frac{x-4}{3} } \\y = \sqrt{\frac{x-4}{3} } + 2$

Hence the inverse of the function is $f^{-1}x= \sqrt{\frac{x-4}{3} } + 2$
