basic cellular phone plan costs $36 per month for 50 calling minutes. Additional time costs $0.90 per minute. The formula C=36+0.90(x−50) gives the monthly cost for this​ plan, C, for x calling​ minutes, where x>50.   How many calling minutes are possible for a monthly cost of at least $54 and at most $72? For a monthly cost of at least $54 and at most ​$72​, nothing≤x≤nothing calling minutes are possible.

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.
