The man rows at v1 miles per hour and walks at v2 miles per hour. Let 1 and 2 be the magnitudes of the angles. Show that the man will reach point Q in the least time when sin(1) v1 = sin(2) v2 .

Cor d? ? me ? 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.
