A refrigerator runs at a mean temperature of 2.5 degrees Celsius with a standard deviation of 0.8 degrees Celsius. The manufacturers want to also sell the
refrigerator in countries that use degrees Fahrenheit, so they convert the data by
applying the formula to each data point: Fahrenheit = 9/5 (Celsius) + 32. If each
temperature is converted to degrees Fahrenheit, what will the mean and
standard deviation of the data of the new temperatures be? *

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?
