Lines a and b are parallel. If the slope of line a is 3 , what is the slope of line b? A. -3
B. -1/3
C. 1/3
D. 3

D.

Step-by-step explanation:

They are parallel and therefore has the same slope.

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.
