A filter removes 75% of the impurities of water that is passes throught it. Multiple filters can be used together to increase the purity of the water. This situation is represented by A=0.25^N, where A is the proportion of impurities remaining and n is the number of filters used. What proportion of impurities remians when four filters are used, to the nearest ten thousandth? Explain
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.
A filter removes 75% of the impurities of water that is passes throught it. Multiple filters can be used together to increase the purity of the water. This situation is represented by A=0.25^N, where A is the proportion of impurities remaining and n is the number of filters used. What proportion of impurities remians when four filters are used, to the nearest ten thousandth? Explain
Given:
A filter removes 75% of the impurities of water that is passes through it. Multiple filters can be used together to increase the purity of the water. This situation is represented by , where A is the proportion of impurities remaining and n is the number of filters used.
