Answer:
Step-by-step explanation:
3.6 x 10 = 36
36^4 equals 1,679,616
Unless you wrote the equation wrong in which case I would need to see the right equation ofc
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:
The graph is symmetric. The mean and median are about equal in a symmetric graph. The median is shown as 109, so the mean is approximately 109.
Step-by-step explanation:
The graph is symmetric.
Because the graph is symmetric, the mean and median should be approximately equal.
According to the graph, the median is 109. Therefore, the mean is approximately 109.
1+3=4
A counterexample is an a example that proves the statement false.
1+3 are not even numbers but they equal an even one, so it just proved the statement wrong.
