Thanks for telling. i would totally get caught off guard if the staff are mostly robots- robots scare me for whatever reason. probably because i have a feeling they might turn on us humans and destroy the world or something along those lines.

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

Point (20, 5) is on the graph of inverse variation. Which of the following ordered pair is on the graph?.

Bess [88]

The point $(10, 10)$ is on the graph.

<h3>Procedure - Inverse variation</h3><h3 /><h3>Inverse variation model</h3><h3 />

An <em>inverse</em> variation is represented by the following formula:

$y = \frac{k}{x}$ (1)

Where:

$x$ - Independent variable.
$y$ - Dependent variable.
$k$ - Proportionality constant.

We can eliminate the proportionality constant by creating the following relationship:

$x_{1}\cdot y_{1} = x_{2}\cdot y_{2}$ (2)

<h3>Determination of another point</h3>

If we know that $x_{1} = 20$ , $y_{1} = 5$ and $x_{2} = 10$ , then the remaining variable is:

$y_{2} = \left(\frac{x_{1}}{x_{2}} \right)\cdot y_{1}$

$y_{2} = \left(\frac{20}{10} \right)\cdot (5)$

$y_{2} = 10$

The point $(10, 10)$ is on the graph. (Correct choice: C) $\blacksquare$

The moment of inertia about the axis of a solid cylinder is _____ the moment of inertia of a cylindrical shell having the same m

marin [14]

The moment of inertia about the axis of a solid cylinder is <u>less than</u> the moment of inertia of a cylindrical shell having the same mass and radius.

<h3>How to calculate moment of inertia?</h3>

Mathematically, the moment of inertia for a solid cylinder is calculated by using this formula:

I = (1/2)mr²

<u>Where:</u>

m is the mass.

r is the radius.

In conclusion, the moment of inertia about the axis of a solid cylinder would be <u>less than</u> the moment of inertia of a cylindrical shell that has the same mass and radius because the mass of the solid cylinder must be taken near the axis of rotation, which makes it smaller.
