One walks east at 3 mi/h and the other walks northeast at 2 mi/h. How fast is the distance between the people changing after 15 minutes? 50 49. A runner sprints around a circular track of radius 100 m at a constant speed of 7 m/s. The runner's friend is standing 2.9 Linear Approximations and Differentials We have seen that a curve lie fact, by zooming in toward M/ at a distance 200 m from the center of the track. How fast is the distance between the friends changing when the distance between them is 200 m? 0. The minute hand on a watch is 8 mm long and the hour hand is 4 mm long. How fast is the distance between the tips of the hands changing at one o'clock?

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.
