During the next 24 hours, 20 percent of the amount of the drug in the body is eliminated. (a) Write a difference equation and initial conditions giving the amount of the drug in Mr. Lorenzo's body immediately after he takes the nth capsule. (b) How much of the drug will there be in Mr. Lorenzo's body immediately after he takes the eighth capsule? (c) To what level will this drug eventually accumulate in his body? 26. In Mayville, 90 percent of the existing dog licenses are reissued each year, and 1200 new licenses are issued. In 2000 there were 15,000 dog licenses issued.

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.
