(38.) Angle of elevation An angle of elevation is the angle between the horizontal line and the line of sight of an object above the horizontal. In the diagram, a plane is flying horizontally across the sky and ZRST represents the angle of elevation. How is the angle of elevation affected as the plane flies closer to the person? Explain.

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.
