Juan is finding the equation of a median-median line. he found that the equation of the line through the first and third summary points is y = –4.5x + 843. then, he found that the equation of the line through the second summary point and parallel to the first line is y = –4.5x + 942. what is the equation of the median-median line?

1-for what value of x is line a parallel to line b 2-for what value of x is line a parallel to line b

Ivan began dividing g2  – 6 by g + 1, noting that . he started by placing g in the quotient, as shown below.what is g2  – 6 divided by g + 1? g –  1 –  g + 1  – g  –  7 + g  –  5  + 

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.
