Why are three partial product in 1 (a) and only two partial product s in 1 (b)?

because partial 1(a) and partial 1(b) are the same.

They are the same.

Please let me know if you need anymore help.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

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.
