The relative frequency distributions of the values in data set A and data set B are shown in two histograms, where each interval shown includes its left endpoint and excludes its right endpoint. The number of values in A is 2 times the number of values in B, Data set C consists of the values in A and the values in B. Which of the following could be the median of the values in C?
List A contains 11 different positive integers that are less than or equal to 20. List B contains all the integers in A except for the greatest integer. The average (arithmetic mean) of the integers in A is $$x$$ , and the average of the integers in B is $$y$$ .
Quantity A: $$x$$
Quantity B: $$y+1$$
The average (arithmetic mean) of the five numbers $$x_1$$ , $$x_2$$ , $$x_3$$ , $$x_4$$ and $$x_5$$ is $$v$$. If the average of the five numbers $$x_1-v$$ , $$x_2-v$$ , $$x_3-v$$ , $$x_4-v$$ and $$x_5-v$$ is $$w$$ , then $$w$$ =?
