It appears that the question you're asking requires the regression equation from a previous question (question 19) to predict the value of $y$ when $x = 12$.

However, since the regression equation is not included in this image, I'll need you to either:

1. Share the regression equation if you have it, or
2. Provide a picture of the relevant regression equation from question 19.

Once I have the equation, I can easily calculate $y$ when $x = 12$ for you. Let me know how you'd like to proceed!

Also, would you like details on how the regression equation works for future questions?

Here are 5 related questions to expand your understanding:

1. What is the general form of a simple linear regression equation?
2. How do you determine the slope and intercept of a regression line?
3. What is the meaning of $R^2$ (the coefficient of determination) in regression analysis?
4. How does one calculate residuals in a regression model?
5. What are common applications of regression analysis in real-world scenarios?

Tip: When using regression equations, always make sure your predicted value falls within the range of your dataset to avoid inaccurate extrapolation.
