Poster 7 has vertices V'(50, -40), X'(30, -40), Y'(30, - 70), and Z' (50,- 70). Which transformations of poster 4 produce the location of poster 7? Select all that apply. A: A reflection of the location of poster 4 across the x-axis following by a translation right 10 inches and down 70 inches

B: A reflection of the location of poster 4 across the y-axis followed by a translation down 40 inches and right 70 inches

C: A translation of the location of poster 4 right 10 inches bright down 40in

D: a translation of the location of poster 4 right 10in followed by a reflection across the x-axis and a translation down 70in

E: a translation of the location of poster 4 down 40in followed by a reflection across the y-axis and a translation right 70in​

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.
