A baseball is thrown from the stands 25 ft above the field at an angle of 40" up from the horzontal. When and how far away will the ball strike the ground if its initial speed is 34 f/sec? Assume ideal projectile motion, that is, that the baseball undergoes constant downward acceleration due to gravity but no other acceleration; assume also that acceleration due to gravity is -32 feet per second-squared.) The ball will hit the ground after seconds. The ball will hit the ground a horizontal distance of feet away.

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.
