1) Suppose that a photocopy machine can reduce copies to 65 percent of their original size. By copying an already reduced copy, further reductions can be made. a) If a page is reduced to 65 percent, what percent enlargement is needed to return it to its original size? answer = ( ) percent b) Estimate the number of times in succession that a page must be copied to make the final copy less than 15 percent of the size of the original. number of times = ( )
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
