The operations manager of a mail order house purchases double (d) and twin (t) beds for resale. each double bed costs $500 and requires 100 cubic feet of storage space. each twin bed costs $300 and requires 90 cubic feet of storage space. the manager has $75,000 to invest in beds this week, and her warehouse has 18,000 cubic feet available for storage. profit for each double bed is $300 and for each twin bed is $150. the manager’s goal is to maximize profits. what is the weekly profit when ordering the optimal amounts?

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
