Classify each entry as a mathematical expression (EXP), or a mathematical sentence (SEN). Classify the truth value of each entry that is a sentence: (always) true (T); (always) false (F); or sometimes true/sometimes false (ST/SF). The first two are done for you. (sample) 1 + 2 EXP (sample) 1 + 2 = 3 SEN, T 12 x − 1 = x − 1 = 1 + 2 + x x ÷ 3 =
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.
9–15: Classify each entry as a mathematical expression (EXP), or a mathematical sentence (SEN).
Classify the truth value of each entry that is a sentence: (always) true (T); (always) false (F); or sometimes true/sometimes false (ST/SF). The first two are done for you.
(sample) 1 + 2 EXP
(sample) 1 + 2 = 3 SEN, T

- x ÷ 3 =
- 1 + 2 + x = x + 1 + 2
- Use the English noun ‘Julia’ in three sentences: one that is true, one that is false, and one whose truth cannot be determined without additional information.
- Use the mathematical expression ‘ 3 ’ in three sentences: one that is true, one that is false, and one whose truth cannot be determined without ad ditional information.
- Use the mathematical expression ‘ x ’ in three sentences: one that is always true, one that is always false, and one whose truth cannot be determined without additional information.
