Aaron, Fetti and Jaydan are roommates. They live in a same apartment and agreed to pay their parts of Utility, Electricity and WIFI. However, Fetti and Jaydans are brothers, Fetti agreed to pay for his little brother for everything which means he will pay for 2/3 of the Utility, Electricity and WIFI, Aaron holds the AEP account for Electricity, and this month’s electricity bill is $203. Fetti hold the utility and the wifi account, utility is $386 for this month, wifi is $75 for this month. Who owe money to whom and how much? (Remember, Aaron needs to pay 203 out of his pocket, and Fetti needs to pay 386+75=461 out of his pocket).

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.
