A phone company charges a standard monthly rate of $13 plus ten cents for every minute of long distance calls. If x represents the number of minutes of tong distance calls in a m and y represents the total monthly charges, which of the following equations represents the relationship between x and y? O A y = 13 + 0.1x O B. y = 13x^(0.1) OC.y = 13x+0.1 O D.y = 13(0.1^x) QUESTION 23

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.
