If a third plane could be drawn which contains both lines a and b, then lines a and b must be parallel. <span>if two lines do not intersect on the same plane, they are parallel. Furthermore, if a line is in a plane and another line is in a parallel plane, you cannot draw another plane </span><span>which contains both lines a and b, only if the lines are parallel.</span>
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.
