The figure below shows a lighthouse that is L = 180 feet from a long straight wall on the beach. The light in the lighthouse rotates through one complete rotation once every 4 seconds. Find an equation that gives the distance d in terms of time t. d = ft Then find d when t is Lsecond and seconds. (If an answer is undefined, enter UNDEFINED.) t=s d- ft 2 What happens when you try t = 1 second in the equation? (If an answer is undefined, enter UNDEFINED.) d = ft How do you interpret this?

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.
