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 re…

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.

Chapter 10.7, Problem 56AE

Projectile Motion Suppose that Karla hits a golf ball off a cliff 300 meters high with an initial speed of 40 meters per second at an angle of $45^{\circ}$ to the horizontal on the Moon (gravity on the Moon is one-sixth of that on Earth).

a. Find parametric equations that model the position of the ball as a function of time.

b. How long is the ball in the air?

c. Determine the horizontal distance that the ball travels.

d. When is the ball at its maximum height? Determine the maximum height of the ball.

e. Using a graphing utility, simultaneously graph the equations found in part (a).
