Find the sum.
(12p+ 9) + (4p- 3)
OA. 16p+ 12
OB. 16p+ 6
OC. 12p + 6
OD. 16p 6

so the answer is 16p+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.
