The sets A and sets B contains items called elements

It is true that the set A is equal to set B

<h3>How to determine the true statement?</h3>

The sets are given as:

Set A and set B

Since the sets have the same power set, then we have:

P(A) = P(B)

The above means that:

For every element X in A, then the element is also in B

And

For every element Y not in A, then the element is also not in B

So, we can conclude that:

All subsets of the set A are subsets of the set B and vice versa

Hence, the set A is equal to set B

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

Which equation represents energy being absorbed as a bond is broken.

konstantin123 [22]

There are different ways energy is absorbed. The equation that represents energy being absorbed as a bond is broken is H2 + energy → H + H

Energy is known to be taken in or absorbed so as to break bonds. Bond-breaking is referred to as an endothermic process. In this process, Energy is released when new bonds form. Bond-making is also known to be an exothermic process.

Potential energy is simply known to be the type of energy that is linked to an object's potential to do work.

Chemical energy is known to be the type of energy that is said to be released from the breakdown of chemical bonds.

See full question below

Which equation represents energy being absorbed as a bond is broken?

answer choices

H + H → H2 + energy

H + H + energy → H2

H2 + energy → H + H

H2 → H + H + energy
