Charlene made the sketch below in order to find the height x of a pole. she positioned a mirror on the ground so that she could see the reflection of the top of the pole. her height, her distance from the mirror, and her line of sight to the mirror determine the smaller triangle. the pole’s height, its distance from the mirror, and the distance from the top of the pole to the mirror form a larger similar triangle. find the height of the pole to the nearest tenth.

Need now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
