Regression Equations
Regression equations are mathematical expressions that are used to predict the value of a dependent variable based on the value of one or more independent variables. In the given problem, we have two regression equations:
2x + 5y - 9 = 0
3x - y - 5 = 0
Finding Mean X and Mean Y
To find the mean value of x and y, we need to solve the above regression equations simultaneously.
Multiplying the first equation by 3 and the second equation by 2, we get:
6x + 15y - 27 = 0
6x - 2y - 10 = 0
Simplifying the above equations, we get:
17y = 37
y = 37/17
Substituting the value of y in the first equation, we get:
2x + 5(37/17) - 9 = 0
2x = (9 - (5*37)/17)
x = (9 - (5*37)/17) * 1/2
x = 13/17
Therefore, the mean value of x is 13/17 and the mean value of y is 37/17.
