He length of a rectangle is represented by the function l(x) = 4x. the width of that same rectangle is represented by the function w(x) = 7x^2 − 4x 2. which of the following shows the area of the rectangle in terms of x?
(l w)(x) = 7x^2 2
(l w)(x) = 7x^2 − 8x 2
(l ⋅ w)(x) = 28x^3 − 16x^2 8x
(l ⋅ w)(x) = 28x^3 − 4x 2

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.
