5(-3p + 7) + 5(p - 1)

The answer would be -10p+30.

Step-by-step explanation:

Distrubuting the 5 to -3p and 7 and 5 to p and -1 would be the first step.

Once you did that, you would get -15p+35+5p-5. Now just add -15p to 5p and add 35 to -5 and you'll get -10p+30.

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.
