Answer: "always" for both

A line segment is <u>always</u> similar to another line segment, because we can <u>always</u> map one onto the other using only dilations and rigid transformations.

==================================

Explanation:

A dilation is where we grow or shrink an object. In this case, it would be lengthening or shortening a line. We can dilate any line to get it to any desired length we want. Then to make sure it matches up perfectly with the other line, we can perform translations (aka shifting) and rotations.

In other words, if we have four points A,B,C,D then it is possible to use dilations and rigid transformations to map points A,B to points C,D. The first segment AB would map to segment CD.

Sounds that you have several answer choices.  If that's the case, you need to share those choices.  All of them are probably inequalities.

Answer:

P(25

And we can find this probability with this difference:

P(0

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.  

P(0

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 hous spent studying the week before final exams of a population, and for this case we know the distribution for X is given by:

X \sim N(25,6)  

Where \mu=25 and \sigma=6

We are interested on this probability

P(25

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(25

And we can find this probability with this difference:

P(0

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.  

P(0
