You decide to use the K-Nearest Neighbors (KNN) model on the dataset to predict car type. Your friend worked for 4 years and attended college for 4 years. If K is set to 7 and the model uses Euclidean distance, which car type will be predicted for your friend?

Initially, point x1 is chosen as Centroid1 and point x2 is chosen as Centroid2. Using Euclidean distance measure, what will be the final X and Y values of the Centroids after the first iteration of the K-mean clustering algorithm?
