📌 Solution: Rewrite the logarithmic equation in exponential form: $ x + 3 = 2^4 $. Simplify $ 2^4 = 16 $, so $ x = 16 - 3 = 13 $.

📌 \boxed{13}Question: At a science fair, a judge evaluates 12 projects, each scored on creativity and technical skill. The average creativity score is 84 with a standard deviation of 6, and the average technical score is 78 with a standard deviation of 5. If the correlation coefficient between creativity and technical scores is 0.6, what is the predicted technical score for a project with a creativity score of 90?

📌 We use the regression equation to predict the technical score based on creativity, given the correlation coefficient, standard deviations, and mean values.

📌 Let $ x $ be the creativity score, and $ y $ be the technical score.

📌 $ \mu_x = 84 $, $ \sigma_x = 6 $

📌 $ \mu_y = 78 $, $ \sigma_y = 5 $

📌 $ r = 0.6 $

📌 $ x = 90 $
