Ricardo is considering two monthly plans a dog-walking service offers. Plan 1 charges $3 per walk plus $10 for grooming at the end of each month.
Plan 2 charges $5 per walk and then offers free grooming at the end of each month.
Part A. Enter an equation to model the number of walks, w, when the two plans cost the same amount.

Part B. How many walks will it take for the two plans to cost Ricardo the same amount?

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.
