Answer:
Explanation:
Regression equation is a statistical method used to determine the relationship between two or more variables. In this problem, we are given two regression equations as 3x + y = 11 and 2x + 5y = 26.
To determine which one is the regression equation of y on x, we can use the following steps:
Step 1: Solve each equation for y
3x + y = 11
y = 11 - 3x
2x + 5y = 26
5y = 26 - 2x
y = (26 - 2x)/5
Step 2: Compare the equations to the regression equation of y on x
The regression equation of y on x is given by:
y = a + bx
where a is the intercept and b is the slope.
We can see that the first equation, y = 11 - 3x, is in the form of the regression equation of y on x. Therefore, the first equation is the regression equation of y on x.
Step 3: Interpretation of the result
The regression equation of y on x tells us the relationship between x and y. In this case, y = 11 - 3x means that for every one unit increase in x, y decreases by 3 units. This relationship can be used to make predictions about y based on the value of x.
Conclusion:
The regression equation of y on x is given by y = 11 - 3x. The second equation, 2x + 5y = 26, is not in the form of the regression equation of y on x.
