In the xy-plane, the vertices of triangle $$T_n$$, are defined as the points $$(n, 0), (3n+1, 0)$$,and $$(n, 2n^2+2n)$$ for all positive integers n. The perimeter of triangle $$T_5$$ is how much greater than the perimeter of triangle $$T_4$$ ?
In a candy factory, quality-control tests were conducted on six 1,000-piece batches of candy. The numbers of pieces of candy that were rejected in these batches were 4, 3, 8, 6, 3, and 12, respectively. If the median of these numbers is used topredict the number of rejections in each 1,000-piece batch of candy produced by this factory, what is the total number of rejections predicted for 20 such batches?
