There are six basic functions of IT.
1. Capture: Compiling detailed records of activities.
2. Processing: Converting, analyzing, computing and synthesizing all forms of data and information.
3. Generation: Organizing information into a useful form.
4. Storage: Retaining information for further use.
5. Retrieval: Locating and copying stored data or information for further processing or for transmission to another user.
6. Transmission: Distributing information over a communication network.
Answer:
4.24
Explanation:
First you find the mean of the data set, which is 7. Then to find standard deviation you have to follow the formula which tells you to subtract the mean from each number under the square root : √(2 - 7)^2 + (9 - 7)^2 + (10 - 7)^2 + (4 - 7)^2 + (8 - 7)^2 + (4 - 7)^2 + (12 - 7). Once you solve the parenthesis you square it, once you square it the negatives won't matter. That will leave you with this : √(25 + 4 + 9 + 9 + 25). The formula tells you to find the sum of those numbers (which is 72) then subtract one from how many numbers there are, 5 - 1 = 4, and divide your sum by that number. So 72 / 4 = 18. Then you find the square root of 18 and that becomes your answer.
This is a good question! Knowing what others think about a product is very helpful before purchasing it. Also knowing the rating is good too. For example I bought a dress off of Amazon and I never looked at the ratings before I bought it, and once I got it in the mail...It looked NOTHING like the picture.
I hope this was helpful for you!

Answer:
b. the cluster centers for the current iteration are identical to the cluster centers for the previous iteration.
Explanation:
K-mean algorithm is one of the mot widely used algorithm for partitioning into groups of k clusters. This is done by partitioning observations into clusters which are similar to each other. When using k-mean algorithm, each of the different clusters are represented by their centroid and each point are placed only in clusters in which the point is close to cluster centroid.
The K-Means algorithm terminates when the cluster centers for the current iteration are identical to the cluster centers for the previous iteration.
