Neglecting air resistance, the height h (in meters) of an object thrown vertically upward from the ground with initial velocity vo is given by h(t) = vot - g² where m g= 9.81, is the earth's gravitational constant and t is the time (in seconds) elapsed since the object was released. Find the velocity of the object. Choose the correct answer. dv O A. v(t) = vo dg gt dt dt O B. v(t) = vo - gt OC. v(t) =t- O D. v(t) = Vo - 2 gt Find the acceleration of the object. Choose the correct answer.

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.
