Below you find patient data from the HyperClinic. We'd like to cluster our patients into groups, so we may gain new insights about them:
| id | heart rate (bpm) | CK-MB | total cholesterol (mg/dL) |
| 1 | 81 | 12 | 120 |
| 2 | 65 | 14 | 200 |
| 3 | 40 | 54 | 130 |
| 4 | 140 | 2 | 250 |
The points with id=1, id=4 were selected as centroids in the initialization step. Calculate the Euclidean distances between the points and assign clusters to the points. Now recompute the coordinates of the centroid with id=1. In the answer field type the sum of new coordinates, rounded to two decimal places.
