Explanation Given: The total amount of $ 6050 is on one rainy day and six sunny days. The total amount of $ 7400 is on four rainy days and three sunny days. Calculation: Consider the amount on rainy day be x and the amount on sunny day be y . Write the equation for the total cost for first week. x + 6 y = 6050 …...…... (1) Write the equation for the total cost for second week. 4 x + 3 y = 7400 …...…... (2) Multiply the equation (2) by − 2 as; − 2 ( 4 x + 3 y ) = − 2 ( 7400 ) − 8 x − 6 y = − 14800 …...…... (3) Add the equations (3) and (1), x + 6 y = 6050 − 8 x − 6 y = − 14800 ( 1 − 8 ) x + ( 0 ) y = ( 6050 − 14800 ) Thus, the value of y is; − 7 x = − 8750 x = 8750 7 = 1250 Substitute 1250 for x in equation (1) as;

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…
