A geographically proximate group of interconnected companies and associated institutions in a particular field, linked by commonalities and complementarities.. Clusters encompass an array of linked industries and other entities important to competition. They include:. Water is ALWAYS in the atmosphere!. Earth’s water is mostly found in the oceans, but it is also found in lakes, rivers, ice sheets, in plants, and underground.. It can be present as a solid (like snow), liquid (rain), or gas (water vapor). . When is the assessment?. Year 7 – November 17. th. -28th. Year 8 – November 17. th. -28th. How long is the assessment?. 50 minutes. What will I need to do?. Read two poems and answer questions on them. . K-means Clustering. - . Each cluster is represented by the . center. of the cluster.. The algorithm steps:. Step 1: Choose the number of clusters, . k. . . Step 2: Randomly generate . k. clusters and determine the cluster centers, or directly generate .
