Problem 02: (a) A predator is flying at a constant speed along with a constant height of 100 m that will take it directly over a prey at ground level. The prey, at a given instant notes that the angle between him and the predator is and is decreasing at radians per seconds. Find the speed of the predator. 20 (b) Continue as part (a), if the predator comes towards the prey at a constant angular rate of change; what is the speed of the predator when it is directly over the head of the prey. (c) Is the predator slowing down or speeding up as it approaches to the prey? Justify your conclusion.

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.
