  A)  B. 18-6

  B)  20÷4

  C)  20

Step-by-step explanation:

Part A

The order of operations tells you that the first step is to evaluate any expressions in parentheses. Here, that means you first evaluate (18 -6).

__

Part B

After parentheses have been removed, the next step is to perform multiplication and division. Here, there is only one term involving division, so you divide 20 by 4 as your second step.

__

Part C

After you have done parts A and B, your expression is ...

  3 + 12 + 5

The value of this sum is 20.

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.
