Estimates of the financial information for a new product show the following information: Fixed cost: $9,000 Variable cost: $6.50/unit Revenue: $21/unit The number of units sold is assumed to follow a normal distribution with a mean of 800 and a standard deviation of 100. Use the random numbers .51, .97, .58, .22, and .16 to simulate five trials. What is the net profit for each trial

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?

Which of the following is the result of expanding

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?
