Volunteer drivers are needed to bring 80 students to the championship baseball game. Drivers either have cars, which can seat 4 students, or vans, which can seat 6 students. The equation 4c + 6v= 80 describes the relationship between the number of cars, c, and number of vans, v, that can transport exactly 80 students. Select all statements that are true about the situation. Copied for free from openupresources.org Select all that apply: DA: If 12 cars go, then 2 vans are needed. OB: c = 14 and v = 4 are a pair of solutions to the equation. OC: If 6 cars go and 11 vans go, there will be extra space. OD: 10 cars and 8 vans isn't enough to transport all the students. UE: If 20 cars go, no vans are needed. 100% OF: 8 vans and 8 cars are numbers that meet the constraints in this situation.

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.
