Law 19983 on

Classified in Mathematics

Written at on English with a size of 4.03 KB.

1. Give a direct proof of the following: “If x is an odd integer and y is an even integer, then x + y is odd”.

Suppose x = 2k + 1, y = 2l. Therefore x + y = 2k + 1 + 2l = 2(k + l) + 1, which is odd.

2. Consider the following theorem: If n is an even integer, then n + 1 is odd. Give a proof by contraposition of this theorem.

Suppose n + 1 is even. Therefore n + 1 = 2k. Therefore n = 2k − 1 = 2(k − 1) + 1, which is odd

3. Consider the following theorem: If n is an even integer, then n + 1 is odd. Give a proof by contradiction of this theorem.

Suppose n = 2k but n + 1 = 2l. Therefore 2k + 1 = 2l (even = odd), which is a contradiction

4. Prove the following theorem: n is even if and only if n2 is even.

If n is even, then n2 = (2k)2 = 2(2k2), which

This document outlines the steps to calculate production costs, including equivalent units and costs for work-in-progress (WIP) and finished goods.

Step 1 - Determine the units of product to account for (how much inventory do we need to track?)
Units in beginning WIP30,000
+ Units started this period155,000
= Total units to account for185,000
Step 2 - Determine the number of units of product accounted for (where is the inventory at the end of the month?)
Step 2 MUST equal Step 1
Units in beginning WIP30,000
+ Units started and completed during the period119,000149,000 finished - 30,000 started last month = 119,000 started and finished this month
