Will mark brainliest! which choice could be the equation of a line perpendicular to the line represented by this equation? y = 5 a. y = 4x− 9 b. y= -1/5x c. y = 5x d. x = 5

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
