Which of the following is(are) true? I. The mean of a population depends on the particular sample chosen. II. The standard devia

Margarita [4]

Answer:

II and III

Step-by-step explanation:

From statement II in the question, it is true that the standard deviations of two different samples from the same population may be the same. The population standard deviation is a fixed value calculated from every individual in the population. A sample standard deviation is calculated from only some of the individuals in a population.

Also from statement III, it is true that statistical inferences can be used to draw conclusions about the populations based on sample data. The mean of a population does not necessarily depends on the particular sample chosen. Therefore statement I is false.

What is 3 1/3 as a percent?

Nikitich [7]

Answer:

$333.3\%$

Step-by-step explanation:

We want to express 3⅓ as a percentage.

Let us first of all rewrite 3⅓ as decimals to obtain:

$3 \frac{1}{3} = 3.3333...$

To express this as a percentage, we multiply by 100%

$3 \frac{1}{3} = 3.3333... \times 100\%$

This multiplies to give us:

$3 \frac{1}{3} = 333.3\%$

Divide. Express the quotient in simplest form.<br> x^2−x−12/2x^2÷x^2+x−6/2x^3

sertanlavr [38]

Hey there!

These are technically expressed as fraction. When you divide a fraction by another, you can replace the second fraction with its reciprocal and you can now multiply the fractions together instead.

$\frac{x^2-x-12}{2x^2} / \frac{x^2+x-6}{2x^3}$

$\frac{x^2-x-12}{2x^2} * \frac{2x^3}{x^2+x-6}$

Now, just multiply across the top and the bottom. You can first cancel out any terms that are repeated or similar.

$\frac{12}{2x^2} * \frac{2x^3}{-6}$

$\frac{2}{x} * \frac{1}{-1}$

$\frac{2}{-x}$

Your answer will be $\frac{2}{-x}$ .

Hope this helped you out! :-)
