The distribution of the ages of cars in a parking lot is known to be skewed with an average age of 4.6 years and a standard deviation of 2.4 years. Which statement below is true?
A. We cannot make conclusions about the ages of the car because we do not know how large the parking lot is that contains the cars
B. About 68% of the cars are between 2.2 and 7 years old
C. 34% of the cars in the parking lot are between 2.2 and 4.6 years old
D. We are unable to apply the Empirical Rule because the data is not approximately normal

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
