Step 1: Choose one equation to begin. (Suggestion: Choose the equation that has a variable already isolated or close to being isolated.) x + 2y = 3 2x + 3y = 1 %3D Step 2: Is a variable isolated? If Yes, continue to Step 3. If No, isolate one of the variables. Step 3: Box the expression that is equal to the isolated variable. Step 4: Using the other equation, substitute the boxed expression for the equations, substitute the known value isolated variable and solve for the only and solve for the unknown value. variable left. Step 5: Using either of the original Step 6: Check your solution and write your answer:

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.
