A political mailing will have several pages on the economy, the military, and the environment. The total number of these pages in the booklet should not be greater than 110, including at most 20 pages on the economy. For the target group that will receive the booklet, market research suggests that there will be a positive impact proportional to 5 times the number of pages on the economy, a positive impact proportional to 3 times the number of pages on the military, and a positive impact proportional to 2 times the number of pages on the environment. The editor insists that the number of pages on the environment be at least twice as many as the number on the military. Find the number of pages that should be devoted to the economy, the military, and the environment. (Hint: Write the constraint involving environment and military pages in the form ≤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.
