1 is 9,000 just round up or down and then mulitpy
2 is 6,400
3 is 11,100
4 is 1,200
5 is 189,000
6 is 6,300
7 is 53,000
8 is 4,300
9 is 7,800

2. MNM Corporation gives each of its employees an aptitude test. The scores on the test are normally distributed with a mean of

antiseptic1488 [7]

Answer:

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

$X \sim N(75,15)$

Where $\mu=75$ and $\sigma=25$

The distribution for the sample mean $\bar X$ is given by:

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

b) $\mu$ represent the true average for the scores of the aptitude test

c) We can calculate the z scores and we got:

$z = \frac{70.14-75}{\frac{15}{\sqrt{25}}}= -1.62$

$z = \frac{82.14-75}{\frac{15}{\sqrt{25}}}= 2.38$

And we can calculate the probability with this difference:

$P(-1.62$

d) We can calculate the z scores and we got:

$z = \frac{82.68-75}{\frac{15}{\sqrt{25}}}= 2.56$

And we can calculate the probability with this difference:

$P(Z$

e) We can calculate the z scores and we got:

$z = \frac{78.69-75}{\frac{15}{\sqrt{25}}}= 1.23$

And we can calculate the probability with this difference:

$P(Z$

Step-by-step explanation:

a. What are the expected value, the standard deviation, and the shape of the sampling distribution of $\bar X$ ?

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".

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

$X \sim N(75,15)$

Where $\mu=75$ and $\sigma=25$

The distribution for the sample mean $\bar X$ is given by:

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

b. What is the random variable in this problem? Define it in words.

$\mu$ represent the true average for the scores of the aptitude test

c. What is the probability that the average aptitude test score in the sample will be between 70.14 and 82.14?

We can calculate the z scores and we got:

$z = \frac{70.14-75}{\frac{15}{\sqrt{25}}}= -1.62$

$z = \frac{82.14-75}{\frac{15}{\sqrt{25}}}= 2.38$

And we can calculate the probability with this difference:

$P(-1.62$

d. What is the probability that the average aptitude test score in the sample will be greater than 82.68?

We can calculate the z scores and we got:

$z = \frac{82.68-75}{\frac{15}{\sqrt{25}}}= 2.56$

And we can calculate the probability with this difference:

$P(Z$

e. What is the probability that the average aptitude test score in the sample will be less than 78.69?

We can calculate the z scores and we got:

$z = \frac{78.69-75}{\frac{15}{\sqrt{25}}}= 1.23$

And we can calculate the probability with this difference:

$P(Z$

Can anybody help me on this

snow_tiger [21]

Answer:

1. D

2. A

3. H

4. C

5. G

Step-by-step explanation:

Ok, so let's do this step by step, you'll only need to picture each panel/side individually, not the whole prism at once.

Start at point A, on both the prism and the flat layout.

On the layout, start with point A. You see that the #1 is along the long edge of A, on the same side... if you transpose that to the prism, you will arrive to vertex D. Do you see it?

Then from point 1 (D), we travel again on the long segment... to reach point #2, which is again point A.

For number 3, we see it's across the rectangle shape from F... if we look at that situation on the prism, we arrive at point H.

Point #4 is across point 1 (D) and diagonal to point 2 (A), so it's point C.

Point #5 is at the crossing of points C and F... so it's G based on the prism.
