Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10 meters past the starting line. Chana skated 3 meters per second and Josiah skated 2 meters per second. Here's a graph that shows a system of equations for this scenario where x is the number of seconds since Chana and Josiah started skating and y is the distance in meters from the starting line. What does point F represent in this context?
A) Chana's distance from the starting line at a time when she is behind Josiah
B) Josiah's distance from the starting line at a time when he is behind Chana
C) Chana's and Josiah's distance from the starting line at the time when Chana catches up with Josiah
D) Chana's distance from the starting line at a time when she is farther than Josiah

You decide instead to take the train there. the train will take 135 minutes. convert this into hours and minutes.

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.
