A quadrilateral is plotted on the coordinate plane. Each of its vertices undergoes the same transformation. Which rule below represents a transformation that does NOT preserve the length of the sides of the quadrilateral? (x, y)-x+2, y +5) (x, y)-(-x -2, y-3) (x, y)-(3x-2, y-3) (x, y)-(-x-2, -y-3)

The triangles are similar. what is the value of x? x=

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.

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.
