Answer:
Associative Property
For multiplication, the rule is "a(bc) = (ab)c"; in numbers, this means 2(3×4) = (2×3)4.
(2x-5)(o)(x)-3x-1)
2x-5-3x-1(xo)
-x-6(xo)
-xsqaure o -6xo
Recall that the mean of a given set of numbers is the sum of the numbers divided by the number of numbers, therefore, the mean of the dataset is:

Now, the range of a data set is the difference between the maximum and the minimum, in this case, the maximum is 99, and the minimum is 15 therefore, the range is:

Finally, the standard deviation is given by the following formula:

where N is the sample size, x_i is an element of the set, and x^- is the mean. The standard deviation of the set is:
