A

Step-by-step explanation:

It is A because if you multiply to get the tip from say $10 it would be a 1.50. So to get the total you would take the total times 1.15

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.

think about it deeply and passionately about this property

i am sorry
