Theodore and sarah have a small business selling custom-made t-shirts. they currently sell 150 shirts per month and charge $10 per t-shirt. sarah thinks they can increase their revenue by increasing their selling price, but theodore knows from experience that each $1 increase in price will decrease the number of t-shirts they sell by 8 shirts per month. find an expression for the total monthly revenue theodore and sarah’s business can generate if they change the selling price of their t-shirts. let x represent the number of $1 increases in the price of the t-shirts

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.
