Mean values of x and y for regression lines x y=1 and x-y=1
- The two regression lines are x y=1 and x-y=1.
- To find the mean values of x and y, we need to solve the two equations simultaneously.
- Let's first rearrange the second equation to solve for y: y = x - 1.
- Substituting this value of y into the first equation, we get: x(x-1) = 1.
- Expanding and rearranging this equation, we get: x^2 - x - 1 = 0.
- Using the quadratic formula, we get: x = (1 ± √5) / 2.
- Since the regression lines intersect at a 90-degree angle, the mean value of x is the average of these two solutions, which is x = (1 + √5) / 2.
- To find the mean value of y, we can substitute this value of x into either of the original equations and solve for y.
- Using the first equation, we get: y = 1 / x = 2 / (1 + √5).
- Therefore, the mean values of x and y for the regression lines x y=1 and x-y=1 are x = (1 + √5) / 2 and y = 2 / (1 + √5).
