Explanation As the stopping distance d of a car varies directly as the square of the velocity v of the car, the equation for this direct proportion is given by, d = k v 2 ... ( 1 ) It is given that, for the car moving at 32 mi/h the stopping distance is 52 ft . Therefore, the value of k is obtained by substituting the known values of velocity and stopping distance in the equation (1) as follows

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 p…
