The percent p of prescriptions filled with generic drugs at CVS pharmacies from 2008 through 2014 can be approximated by the model p (t) =2.77t +45.2 8< t < 11 p (t) =1.95t + 55.9 12< t< 14 Use the model to find the percent of prescriptions filled with generic drugs in each year from2008 through 2014
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.
1) The number S of fuel stations that sold comp natural gas in the united state from 2009 to 2015can be approximated by the function
S ( t ) =69t + 151 9< t < 11
= 160t-803 12<t <15
2) The percent p of prescriptions filled with generic drugs at CVS pharmacies from 2008 through 2014 can be approximated by the model
p (t) =2.77t +45.2 8< t < 11
p (t) =1.95t + 55.9 12< t< 14
Use the model to find the percent of prescriptions filled with generic drugs in each year from2008 through 2014
