Answer:
The probability that a randomly selected programmer major received a salary less than 38000 is 0,3085
Step-by-step explanation:
We will assume that the salaries are Normally distributed. Lets call X the salary of a random major programmer in dollars. We want the pprobability of X being less than 38000. For it, we will standarize X. Lets call W the standarization, given by the formula
Lets denote 
the cumulative distribution function of the standard normal variable W. The values of are well known and they can be found in the attached file. Now, lets calcualte the probability of X being less than 38000 using
Since the density function of a standard normal random variable is symmetric, then 
The probability that a randomly selected programmer major received a salary less than 38000 is 0,3085.

Answer:
x= 3 y=3
Step-by-step explanation:
6(3) - 3(3) =9
18 - 9 = 9
As the x-values got to + infinity, the function's values got to + infinity. This is a graph in which the positive end continues to go up indefinitely, meaning the function's values will end up becoming more and more positive as you go along the positive end of the x axis.
You have to add exercise 2 so people can answer it.
