Which equation represents a horizontal line? A. y= -x B. x= y
C. y= 12 D. x= 12

y=12

Step-by-step explanation:

Equation of Horizontal Line always takes the form of y = k where k is the y-intercept of the line. the horizontal line has the equation y = 12

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.
