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

the answer is 90° x = 90 °
-89/40. First, u need to make a common denominator. In this case, u should use 40. Multiply he first term by 5, which get u -25/40. Multiply the second term by 8, which gets u -64/40. Now add the 2 negatives: -25/40 + (-64/40) u get -89/40
I think that the answer is the 2rd choice on the 2nd picture.
