2. (02.02) the figure shows the letter t and four of its transformed images—a, b, c, and d: a letter t is formed on the coordinate plane with endpoints negative 5 comma negative 1, negative 3 comma negative 1, and negative 4 comma negative 3. figure a has endpoints negative 5 comma 3, negative 3 comma 3, and negative 4 comma 1. figure b has endpoints negative 1 comma 2, negative 3 comma 2, and negative 2 comma 4. figure c has endpoints 3 comma negative 1, 4 comma negative 3, and 5 comma negative 1. figure d has endpoints 2 comma 1, 3 comma 3, and 4 comma 1. which of the four images was formed by a reflection of the letter t? (4 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.
