QUADRATIC FORMULA: You are throwing a football on the field. The path of the ball modeled by the equation h(t) = -.51(t+1.02)(t-87) where h is the height above the ground in feet and time in seconds after the ball is thrown. Answer these questions : How high does the ball travel? How long does it take the ball to hit the ground? How high above the ground is the ball when you throw it? Your friend catches the ball when it is 3.2 feet in the air. How long after you throw the ball does your friend catch it?

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.
