A firm making fertiliser produces a new fertiliser QuickGrow. Each 50 kg bag of QuickGrow contains x kg of compound X and (50 – x) kg of compound Y. Each kilogram of X contains 150 g of a particular element and each kilogram ofY contains 80 g of this element. The company wants each 50 kg of QuickGrow to contain 6.24 kg of this element. a Find i an expression in terms of x for the amount of the particular element contained in x kg of compound X and state the units, ii an expression in terms of x for the amount of the particular element contained in (50 – x) kg of compound Y and state the units. b How much of each compound, X and Y, should each 50 kg of QuickGrow contain to give the desired total amount of the particular element?
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.
