Suppose commute times in a large city are normally distributed and that 65.20% of commuters in this city take more than 20 minutes to commute one-way. if the standard deviation of such commutes is 6.3 minutes, what is the mean commute?

Write the fraction 9/50 as a decimal if needed round to the nearest hundredth

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?
