Give the coordinates for points D and E without using any new variables. Then find the midpoint of DE. The image is of a quadrilateral DEBC drawn on a two dimensional graph. The co-ordinate of C is (-a,0) and of B is (0,-b). Vertices E and D are on x and y axis respectively. A. D(0, b), E(a, 0); midpoint of DE=(b2,a2) B. D(0, a), E(b, 0); midpoint of DE=(b2,a2) C. D(0, b), E(a, 0); midpoint of DE=(a2,b2) D. D(0, a), E(b, 0); midpoint of DE=(a2,b2)

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.
