Imagine you are given a sample set of random transactions from an electronics store. assume that there are x transactions in this sample set. this retail store sells macbook pro (mbp), ipod, ipad, and other electronic goods. the number of purchases that include mbp in the database is 500. there were 400 transactions where the customer bought both ipad and mbp. the number of transactions that had ipod is 600, and the likelihood that someone would buy ipod (by itself or with another product) is 0.30.
now, you are interested in knowing more about the following two association rules:
rule a: if a person buys mbp then he/she is likely to buy ipad.
rule b: if a person buys ipod then he/she is likely to buy ipad.
after running a data mining software you found the following information:
rule a: lift ratio is 3.0
rule b: lift ratio is 2.5
confidence of a?

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !

The correct answer to go in the blank would be a) complement.

Why can you not find anything better to do i mean i guess talking to strangers is pretty entertaining
