Which statement represents the biconditional statement of the conditional statements? if the measures of two angles have a sum of 180º, then the angles are supplements. if two angles are supplements, then their measures have a sum of 180º. a. the measures of two angles have a sum of 180º if and only if the angles are supplements. b. the measures of two angles do not have a sum of 180º if and only if the angles are supplements. c. the measures of two angles do not have a sum of 180º if and only if the angles are not supplements. d. the measures of two angles have a sum of 180º if and only if the angles are not supplements.

Find the distance between c and d on the number line c=3 and d=11

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.
