The image of a figure is shown. What are the coordinates of X in the pre-image of the figure if the rule that created the image

nydimaria [60]

The coordinates of X in the pre-image of the figure is (3.2, 0.6) if the transformation rule is T_(-5.2, 1.4)(x, y)

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we can see in the figure.

The transformation rule is T_(-5.2, 1.4)(x, y)

X'(-2, 2)

Before the transformation:

X = (-2+5.2, 2-1.4)

X = (3.2, 0.6)

Thus, the coordinates of X in the pre-image of the figure is (3.2, 0.6) if the transformation rule is T_(-5.2, 1.4)(x, y)

Assuming that the heights of college women are normally distributed with mean 64 inches and standard deviation 1.5 inches, what

professor190 [17]

Answer:

15.74% of women are between 65.5 inches and 68.5 inches.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 64, \sigma = 1.5$

What percentage of women are between 65.5 inches and 68.5 inches?

This percentage is the pvalue of Z when X = 68.5 subtracted by the pvalue of Z when X = 65.5.

X = 68.5

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{68.5 - 64}{1.5}$

$Z = 3$

$Z = 3$ has a pvalue of 0.9987

X = 65.5

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{65.5 - 64}{1.5}$

$Z = 1$

$Z = 1$ has a pvalue of 0.8413

So 0.9987 - 0.8413 = 0.1574 = 15.74% of women are between 65.5 inches and 68.5 inches.

Answer:

[3, 0]: Maximum point is 15

Step-by-step explanation:

When you graph this, all lines will intersect like this, and the maximum point is 15.

This may not be the best explanation I can give you, but I gave you one, and especially since my curriculum was never taught this specific topic, although the concept looks the same.

I am joyous to assist you anytime.
