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

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

Aluminum GuttersOf all the types of gutters to choose from‚ there is a very good reason why aluminum dominates the gutter market. The metal is corrosion-resistant‚ lightweight‚ easy to work with‚ available in wide range of colors‚ and less expensive than the other alternatives. Copper GuttersCopper gutters will not hold up that much better or last longer than aluminum gutters for the added cost. There are certain long term and short term advantages to copper gutters‚ as long as they are installed
