A movie company earns revenue from royalties and movie sales. From 2009 to 2014, the revenue (in millions of dollars) from royalties r and movie sales s can be modeled by the equations r (t) = -0.4t³ + 2.3t² – 3.1t + 4.2 s (t) = 3.8t2 – 2.8t +2.1, where t is the number of years since 2009. a. Find (r + 8) (t). (r+s) (t) b. What does (r + s) (t) represent? The company's total revenue from royalties and movie sales from 2009 to 2014 O The company's total revenue from royalties from 2009 to 2014 O The company's total revenue from movie sales from 2009 to 2014 The average amount of revenue from the company's different revenue sources

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.
