Ise the information given to answer the question. Part B Which statement about the graph is true? he graph shows the relationship between the total cost, t, of purchasing a O The ordered pair (0,0) represents the unit rate of cost per steel beam. eel beam f feet long. O The ordered pair (0,0) represents the unit rate of cost per foot of steel beam. Steel Beam Cost The ordered pair (0,0) represents the fact that zero feet of steel beam costs 120 zero dollars. 108 The ordered pair (0,0) represents the fact that zero feet of steel beam costs 96 one dollar, 84 72 60 48 36 24 12 5 6 7 8 Length (feet) O 1 2 3 4 9 10 11 12 Total Cost (dollars)
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.
