I need help on this exercise
1 answer:
The length of PR is 16 inches.
Solution:
PQR is a triangle and ST is the mid-segment of ΔPQR.
Given ST = 8 inches
By triangle mid-segment theorem,
<em>The segment connecting the mid-points of two sides of a triangle is parallel to the third side and is half of the length of that side.</em>
Multiply by 2 on both sides.
⇒ 16 = PR
The length of PR is 16 inches.

Answer:
The Normal distribution is a continuous probability distribution with possible values all the reals. Some properties of this distribution are:
Is symmetrical and bell shaped no matter the parameters used. Usually if X is a random variable normally distributed we write this like that:
The two parameters are:
who represent the mean and is on the center of the distribution
who represent the standard deviation
One particular case is the normal standard distribution denoted by:
Example: Usually this distribution is used to model almost all the practical things in the life one of the examples is when we can model the scores of a test. Usually the distribution for this variable is normally distributed and we can find quantiles and probabilities associated
