Below is the formula for calculating monthly payments for a fixed-rate loan. M equals P times the fraction with a numerator of i times the quantity 1 plus i end quantity to the power of n times t all over the denominator of the quantity 1 plus i end quantity to the power of n times t end power minus 1 end fraction Part 1: Explain what the following variables represent and how changing each one affects the monthly payment amount: P, i, and t. Part 2: Explain how changing each variable (P, i, and t) affects the total cost of principal and interest over the life of the loan. (5 points)

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.
