Theorem: A line parallel to one side of a triangle divides the other two proportionately. In the figure below, segment DE is parallel to segment BC and segment EF is parallel to AB:

Which statement can be proved true using the given theorem? (6 points)
Segment BD = 12
Segment BD = 4
Segment BF = 16
Segment BF = 9

Negative 5 1/12 + negative 4 1/4 + 6 3/4

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?

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.
