Answer:
1) With initial centroids 10-40, final clusters are
first cluster (6,12,18,24,30)
second cluster (42,48)
And the Sum of Squared Errors (SSE) for the clustering result is 378
2) With initial centroids 10-20, final clusters are
first cluster (6,12,18,24)
second cluster (30,42,48)
And the Sum of Squared Errors (SSE) for the clustering result is 348
Step-by-step explanation:
K-means works as follows
- the points will be clustered according to their distance to the centroids.
- Then centroids are updated as the cluster means.
- This process continues until clusters doesn't change anymore
1) <u><em>initial centroids</em></u> 10-40
first cluster (6,12,18,24) mean:15
second cluster (30,42,48) mean:40
<u><em>new centroids</em></u> 15-40
first cluster (6,12,18,24,30) mean:18
second cluster (42,48) mean:45
<u><em>final centroids</em></u> 18-45
first cluster (6,12,18,24,30) mean:18
second cluster (42,48) mean:45
Sum of Squared errors = +

2)<u><em>initial centroids</em></u> 10-20
first cluster (6,12) mean:9
second cluster (18,24,30,42,48) mean:32.4
<u><em>new centroids</em></u> 9-32.4
first cluster (6,12,18) mean:12
second cluster (24,30,42,48) mean:36
<u><em>new centroids</em></u> 12-36
first cluster (6,12,18,24) mean:15
second cluster (30,42,48) mean:40
<u><em>final centroids</em></u> 15-40
first cluster (6,12,18,24) mean:15
second cluster (30,42,48) mean:40

Answer:
The answer is "(4, -5)".
Step-by-step explanation:
Please find the complete question in the attached file.
In the given image file when we rotate it to 90 degrees clockwise so the value as the rule is
Putting the value in x = 5 and y = 4 then:
