Edgar is constructing a rectangular play area against an exterior wall of his house for his guinea pig. He uses 60 feet of fencing material to enclose 3 sides of the play area. Write an equation to represent l, the length of the play area in feet, as a function of w, the width in feet. 

The triangles in the diagram are congruent. if mzf = 40°, mza = 80°, and mzg = 60°, what is mzb?

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.
