The perimeter of the rectangle is (14,19,28,45) cm. If the rectangle is dilated by a scale factor of 6 to create a new rectangle, the new dimensions are (15cm by 11cm, 30cm and 9cm , 54cm and 5cm , 54cm and 30cm) . The perimeter of the new rectangle is ( 78,84,118,168 ) cm. When comparing the new perimeter to the original perimeter, the new perimeter is ( 1/6 timws less , 6 times greater , 60 times greater ) .

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.
