Which set of data could have been used to create the stem-and-leaf plot shown below?

64, 79, 95, 83, 81, 90, 67, 86, 91, 84, 81, 69, 83, 92

6.4, 7.9, 9.5, 8.3, 8.1, 9.0, 6.7, 8.6, 9.1, 8.4, 8.1, 6.9, 8.3, 9.2

63, 79, 95, 83, 81, 90, 67, 86, 91, 84, 81, 69, 83, 92

6.3, 7.9, 9.5, 8.3, 8.1, 9.0, 6.7, 8.6, 9.1, 8.4, 8.1, 6.9, 8.3, 9.2

1/4 because there is 4 grades.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

35 is an outlier

step-by-step explanation:

6mm^3 or .6cm^3

factor trees are nice.
