Quan plans to spend less than $80 for buying groceries. he plans to spend $68.25 on food and spend the rest on juice. each juice carton costs $3. he is curious how many juice cartons he can purchase before he runs out of money.

(a) use x to represent the number of juice cartons quan can purchase and write an inequality that can be used to solve for x.

(b) solve the inquality. use the solution to determine the number of juice cartons quan can purchase.

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.
