Answer:

Look at the fraction as a division problem.You can do this in your head, by using a calculator, or by doing long division. For example, ¼ is just 1 divided by 4, or 0.25.

Step-by-step explanation:

Take the top number, or the numerator, of the fraction and divide it by the bottom number, or the denominator.

And no, I'm not telling you the answer.

We divide the numerator by the denominator using long division and to convert a fraction topercent, we convert the fraction to decimal and the decimal topercent.

Answer:

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

$X \sim N(\mu,0.08)$

Where $\mu$ and $\sigma=0.08$

Since the distribution for X is normal then the we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And the standard error is given by:

$SE= \frac{0.08}{\sqrt{24}}= 0.0163$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

$X \sim N(\mu,0.08)$

Where $\mu$ and $\sigma=0.08$

Since the distribution for X is normal then the we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And the standard error is given by:

$SE= \frac{0.08}{\sqrt{24}}= 0.0163$

4. Suppose 11 out of 17 students said they were attending the football game. How many students out of 875 would you expect to at

SCORPION-xisa [38]

We have to basically multiply:

11/17 x 475

And simplifying that we get

307.35

And since there can't be .35 person

So out final answer is 307

A dog eats 0.1 lb of food each day how much does he eat in 10 days

Andrei [34K]

Since the dog eats 0.1 pounds of food each day for ten days, the equation to solve this is 0.1 times 10.

0.1 *10 = 1

The dog eats 1 pound of food in 10 days.

REALLY NEED HELP TIMED TEST!!!!!

Umnica [9.8K]

Answer:

a)13x+3

b) -3x-13

c)4x^2-24

d)-3x^2 +3x

Step-by-step explanation:

a) combine like terms

5x-3+8x+6 so combine the -3 and +6 and 5x and 8x

So 13x+3

b)There is an invisible one in front of (2x-5) and an invisible -1 in front of (5x+8). Distribute these.

2x -5 - 5x -8

So -3x-13

c) Distribute the four to everything in the brackets.

4(x^2-6) becomes 4x^2-24

d) Distribute:

-3x (x-1) becomes -3x^2 +3x
