The answer is the fourth one.
The triangle has two equal sides and two equal angles :)
The interval around the mean that contains 95% of the airfare is (250.2,524.2).
Normal Distribution is bell shaped and symmetrical in nature.
We use standard normal to find probabilities of normal distribution
Normal distributions have key characteristics that are easy to spot in graphs: The mean, median and mode are exactly the same. The distribution is symmetric about the mean—half the values fall below the mean and half above the mean. Diagram below shows standard normal figure.
In a normal distribution, 95% of the values fall between mean±2*sd
Give: mean=387.20
sd=68.50
So the interval around the mean that contains 95% of the airfare is (250.2,524.2).

Answer:
Option D is the correct condition that gives 'One pair of opposite sides is congruent'.
Step-by-step explanation:
We have to select the condition from the four options that do not guarantee that a quadrilateral is a parallelogram.
Option D is the correct condition that gives 'One pair of opposite sides is congruent'.
This is because if one pair of opposite sides of the quadrilateral are congruent, then they may not be parallel and hence the quadrilateral may not be a parallelogram. (Answer)
