An aircraft flying at an altitude of 9000ft passes directly over a group of vacationers hiking at 8500 ft. If O is the angle of elevation from the hikers to the aircraft, find the distanced from the group to the aircraft for the given angle (a) 0 = 60°
(b) 0 = 90°
(c) 0 = 130°

(a) The distance d from the group to the aircraft for 0 = 60° is ft
(b) The distance d from the group to the aircraft for 0 = 90° is ft
(c) The distance d from the group to the aircraft for 0 = 130° is ft

Lucy and donavan measured the length of the school garden. lucys measurement is 11.3m and donavans measurement is 113 cm. could both be correct? explain

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.
