WebTo determine which statement is true, we can use mathematical induction. Mathematical induction is a method of proving statements that are true for a set of integers by showing that the statement is true for a base case (usually an integer equal to zero) and then showing that if the statement is true for an integer k, then it is also true for the integer k + 1.

In mathematics, an ordered pair (a, b) is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair (a, b) is different from the ordered pair (b, a) unless a = b. (In contrast, the unordered pair {a, b} equals the unordered pair {b, a}.) Ordered pairs are also called 2-tuples, or sequences (sometimes, lists in a comp… Weba) Show that if seven integers are selected from the first 10 positive integers, there must be at least two pairs of these integers with the sum 11. Hint: Use the Pigeonhole Principle Answer: We can group the first ten positive integers into five subsets of two integers each, each subset adding up to 11: {1,10}, {2,9}, {3,8}, {4,7}, and {5,6}

Answer: 48. Solution: We have to represent 34 as the sum of three squares chosen from 0, 1, 4, 9, 16, and 25. By playing a bit, we see that the only such sums (ignoring order) are 25 + 9 + 0 and 16 + 9 + 9.
