2. Use function notation to represent each statement. a. Six hours after it started raining, the amount of rain was 37 millimeters.

b. The amount of rain 90 minutes after it started raining was the same as the amount 120 minutes after it started raining

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

The measure of one angle of an octagon is two times smaller that of the other seven angles. what is the measure of each angle?

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.
