Give your answer to the nearest integer.
For each value x in a list of values with mean m, the absolute deviation of * from the mean is defined as |x-m|.

The absolute deviations from the mean of the five numbers in list L are 0, 1, 2, 3, and 6. If k is an integer greater than 1, the numbers in which of the following lists have the same absolute deviations from the mean as the numbers in L ?

Indicate all such lists.

Two metal cans are right circular cylinders of different sizes. The interior base of can A has an area of 5π square inches, and the height of the oil in can A is 6 inches. The interior base of can B has an area of 10π square inches, and the height of the oil in can B is 2 inches. Oil is to be moved from can A to can B so that the height of the oil will be the same in both cans. Which of the following is closest to what will be the new height of the oil, in inches?
Every positive integer can be represented uniquely in base $$11$$ by

$$(a_n......a_2 a_1 a_0)_{11}$$= $$a_n(11^{n})+......a_2(11^{2})+a_1(11^{1})+a_0(11^{0})$$

for some nonnegative integer $$n$$. In the expression, the coefficient $$a_i$$ of $$11^i$$ is one of the digits from 0 to 9 or A, which represents 10, for $$0 ≤ i ≤ n$$, but $$a_n≠ 0$$. For example, $$(4A5)_{11}=599$$ because

$$(4A5)_{11}= 4(11^2)+10(11^1)+5(11^0)$$.

What is the value of $$(8,423)_{11}- (6,682)_{11}$$?
If a positive integer that is less than or equal to 1,000 is to be selected at random, what is the probability that at least one digit of the selected integer will be 6?
If an integer is chosen at random from between 3,000 and 3,799, inclusive, what is the probability that the chosen integer will begin with the digits 33 or 34 and end with the digit 0 or 1?
