Assignment 4 April‚ 7 2013 Mat222 In this week of class we have been taught how to evaluate‚ combine and find inverses of working relations or functions. We will be computing‚ composing‚ transforming and finding the inverse of some functions. We are working with the following functions: f(x) = 2x+5 g(x) = x2 -3 h(x) = (7-3x)/3 We have been asked to compute (f – h)(4). (f – h)(4) = f(4) – h(4) So we can evaluate each separately and then subtract. f(4)

Deterministic techniques assume that no uncertain exists in model parameters. A: True An inspector correctly identifies 90% of the time. For the next 10 products‚ the probability that he makes fewer than 2 incorrect inspections is .736. A: Use Binomial table to discover ‚ add 3 probabilities for 0‚1‚2 A continuous random variable may assume only integer values within a given interval. A: False A decision tree is a diagram consisting of circles decision nodes‚ square probability nodes and branches

1. Explain the difference between a “reserve” and a “resource”. What factors influence estimates of reserves and resources for commodities such as minerals or fossil fuels? Resources and reserves are similar in that the both benefit humanity. Resources are materials that can be used to satisfy human needs‚ or used as support. Reserves on the other hand are known deposits with the ability to extract the available material economically; the size of these reserves is not always known or defined

In Mathematics‚ a periodic function is a function that repeats its values in regular intervals or periods. Periodic functions are used throughout science to describe oscillations‚ waves‚ and other phenomena that exhibit periodicity. Periodic functions are those that repeat on a set interval. All trigonometric functions are periodic. They are useful because one can determine the value of the function anywhere in the domain. If a function is periodic‚ then there is some value n for which
