<u>Given</u>:
Let the random variable x is normally distributed with mean
and 
We need to determine the probability of 
<u>Probability of </u>
<u>:</u>
The formula to determine the value of
is given by

Thus, we have;

Simplifying, we get;


Using the normal distribution table, the value of -2 is given by 0.0228

Thus, the value of
is 0.0228
None they are parallel lines - same slope different y intercept
So $39.50 is the price when you are paying full price, which can be represented by 100%. If you’re paying 25% less, than you are only paying 75% of the original price. Simply multiply $39.50 by 75%(expresses as 0.75) to determine the sale price. 39.50(.75)=29.62 The closest value to that is $29.50, so D is the answer.
Substitute the values given.
-2-3(2) then solve
Your answer should be -8
