Answer:

<em>The distribution is skewed (either to the left or to the right).</em>

Step-by-step explanation:

Skewness is the measure of how symmetric the distribution of the data is around its mean. It can be skewed either to the left or to the right (meaning that one of the "tails" of the distribution is longer than the other). This means that the mass your data set's observations tends to accumulate more around one extreme of the distribution than around the other.

A strictly symmetric, normal distribution would have a skewness measure of 0.

A plane is an undefined term because it

Evgesh-ka [11]

Neither A, B or D explains why plane is undefined. All 3 of those answers describe something about plane which is true. Plane indeed can be named using three non collinear points. However, B is telling why plane is undenified. I it described generally, not using a formal definition.

Answer is B

Given that z is a standard normal random variable, find z for each situation. The area to the right of z is .1314. (Round to two

Mumz [18]

Answer:

$P(Z>0.1314) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.1314,0,1,TRUE)" or the standard normal table

$P(Z$

We can use the following excel code: "=NORM.DIST(0.75,0,1,TRUE)" or the standard normal table.

$P(Z>0.01) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.01,0,1,TRUE)" or the standard normal table

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

$P(Z>0.1314) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.1314,0,1,TRUE)" or the standard normal table

$P(Z$

We can use the following excel code: "=NORM.DIST(0.75,0,1,TRUE)" or the standard normal table.

$P(Z>0.01) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.01,0,1,TRUE)" or the standard normal table

Use prime factorization to reduce each fraction 1. 22/165 2. 35/210

yKpoI14uk [10]

Lets find the prime factorization of 22, 165, 35 and 210. Prime factorization of a number is breaking a number down into the set of prime numbers which multiply together to result in the original number.

The prime factorization of the number 22 is:

$22=2\times11$

Similarly, for 165, 35 and 210 we have

$\begin{gathered} 165=3\times5\times11 \\ 35=5\times7 \\ 210=2\times3\times5\times7 \end{gathered}$

Then, we can solve the given questions.

Question 1.

$\frac{22}{165}=\frac{2\times11}{3\times5\times11}$

so we can cancel out the number 11 and get

$\frac{22}{165}=\frac{2}{3\times5}=\frac{2}{15}$

Then, the answer is

$\frac{2}{15}$

Question 2.

$\frac{35}{210}=\frac{5\times7}{2\times3\times5\times7}$

and we can cancel out the number 5 and 7, then we obtain

$\frac{35}{210}=\frac{1}{2\times3}$

then, the answer is

$\frac{1}{6}$

Which of the following shows why rectangle WXYZ is congruent to rectangle W'X'Y'Z'?

blsea [12.9K]

If you rotated the box 90º, the orrientation would not be the same, so it is not D or B.

After rotating 180º, the box will be in the 1st quadrant. If it moved along the x-axis, it wouldnt be there anymore, and the after-picture shows it in the first quadrant still, so the only answer it can be is C.
