Kaylee read a report that said the probability that a randomly selected American is left-handed is 14%. She was
curious how many left-handed students to expect in a class of 25 students.
She simulated 40 classes of 25 students where each student selected had a 0.14 probability of being left-
handed.
Kaylee counted how many left-handed students were in each simulated class. Here are her results:

George has seven boxes of five pencils. giulio three boxes of eight pencils. one of the boys arranges all his pencils equally into two groups. was this george or giulio how many are in each group explain

1- 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.2- 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 the first question?
