Answer:
This is a multicolinearity problem and the student should determine the variable(s) that cause(s) the problem and remove it.
Explanation:
This information means that there exists a linear combination between the independent variables. The problem might have developed due to multicolinearity producing almost perfectly linearly dependent columns.
This could also be as a results of single matrix created when the student use an incorrect indicator variables and included an additional indicator column which created linearly dependent columns.
The department store should consider using RFIDs (Radio Frequency Identification) for tracking inventory. Unlike the wireless barcodes, RFID uses radio waves to communicate with readers. One very common advantage of an RFID is the scanning range. Wireless barcodes, for instance, requires the reader to be close to the barcode before it can see it to scan it. However, RFID systems can scan a tag as long as it is within range. This is important because it reduces wastage of time on labor-intensive processes and increases task speed, convenience, and project turnover.
Many passive RFIDs use tags that are powered by electromagnetic energy. Such energy does not consume power.

Answer:
The answer is "False"
Explanation:
The data link layer is the protocol layer within a program, which controls data movement into a physical wireless connection. This layer is a second layer, that is also known as a collection of communications applications.
- The server network, in which many clients request, and receive service from a centralized server.
- This system provides an interface, that enables a user to request server services and view the server returns results, that's why it is wrong.
