Topic: The graph shows the sales (in millions of dollars) of Peet's Coffee & Tea from 2000 through 2008. Let f(x) represent the sales in year x. a) Find (f(2008) - f(2000) )/ (2008 - 2000) and interpret the results in the context of the problem. b) An approximate model for the function is S(t) 2. 48t2 + 5. 71t + 84. 0 where 0
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
what is the significance in the answer to my math question?
find (f(2008)-f(2000)/2008-2000
It's asking for the sales from 2008 (288.40) and 2000 (84). After filling in the required information and simplifying i got the answer 25.55. But, i cannot figure out what the relation is. I've looked back over our text book and notes and still cannot figure it out.
