On Rational Function Table of Values Exercise 4: Represent the rational function /(x) through its table of values and graph Table of Values -2 <-1 -1 -2 undefined -2 -1 -4 -3

A certain affects virus 0.4% of the population (in a population of 100,000 people, 400 will be infected with the virus). A test used to detect the virus in a person is positive 87% of the time if the person has the virus (true positive) and it is positive 14% of the time if the person does not have the virus (false positive). Fill in the remainder of the following table and use it to answer the questions below. Infected Not Infected Total Positive Test Negative Test Total 400 99,600 100,000

How do you calculate a cohen's, why and when? (maybe a real-life example).

Class: Numerical Methods Textbook: Numerical Analysis 10th Ed by Burden and Faires Topic: Round-off Errors and Computer Arithmetic (Sec 1.2) 3) Two calculations for the true values A (ATRUE = 1,100) and B (BTRUE = 1,000,100) yield the approximate values AAPPROX = 1,000 and BAPPROX = 1,000,000. The approximate values are both off by 100, therefore these values are equally accurate. Does this conclusion make sense? Why or why not?   4) For a 4-digit decimal machine numbers (with exponents in the range -6 ≤ n ≤ 6), find Largest possible number = ________________________ Smallest possible positive number = _____________________
