If x is the average (arithmetic mean) of 10 and y, and y is the average of x and 22, which of the following statements are true?

Indicate all such statements.
A certain data set consists of n values, and the mean of the values is positive. If an additional value equal to 70 percent of the mean is included in the data set to create a new data set, then the mean of the values in the new data set will be 2 percent less than the mean of the values in the original data set. What is the value of n?
Of the following, which best represents the graph of the function $$y=(x^{2}-x)(x-2)$$ $$?$$

Every positive integer can be represented uniquely in base 8 by

$$(a_n......a_2 a_1 a_0)_8$$= $$a_n(8^{n})+......a_2(8^{2})+a_1(8^{1})+a_0(8^{0})$$

for some nonnegative integer $$n$$, where the coefficient $$a_i$$ of $$8^{i}$$ is one of the digits from 0 to 7 for $$0 ≤ i ≤ n$$, but $$a_n ≠ 0$$. For example, $$197=(305)_8$$ because $$197= 3(8^{2})+0(8^{1})+5(8^{0})$$.

Quantity A

The product of the three integers $$(3123)_8, (21740)_8$$, and $$(14)_8$$

Quantity B

The product of the three integers $$(6246)_8, (2174)_8$$, and $$(60)_8$$
