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.
Answer:
The code is given below
Explanation:
The correct syntax would be to place appropriate parenthesis.
(month==1?"jan":(month==2?"feb":(month==3?"mar":(month==4?"apr":(month==5?"may":(month==6?"jun":(month==7?"jul":(month==8?"aug":(month==9?"sep":(month==10?"oct":(month==11?"nov":"dec")))))))))));
Similarly, you can also use the following code:
String[] months = { "jan", "feb", "mar", "apr", "may", "jun", "jul", "aug", "sep", "oct", "nov", "dec" };
int month = 1;
String monthDescription = months[month - 1];
Answer:
a: Twisted pair won't span a 400-foot distance.
Explanation:
The maximum distance that twisted pair cables can support without attenuation is 100 meters which is approximately 328 feet and the two office buildings are 400 feet apart, so it is useless to install a twisted pair cable for such a large distance. A much better option would be to install optic fiber. Though it is a bit expensive but it is the best option in this case.
Hence option (a) is the correct reason for installing an optic fiber cable rather than a twisted pair cable.
Answer:
There are additional security risks associated with using cloud computing over local data storage.
Explanation:
Cloud computing: The term "cloud computing" is described as a process through which an individual tends to access and store various programs and data over the internet rather than his or her computers' "hard drive". However, the term "cloud" here refers to a specific metaphor associated with the internet.
Types:
1. Software-as-a-service or SaaS.
2. Platform-as-a-service or PaaS.
3. Infrastructure-as-a-service or IaaS.
In the question above, the very first option is correct as all other options mentioned over here are incorrect because they aren't related to cloud computing.
Answer:
C) /etc/updatedb.conf
Explanation:
The locate command actually uses the configuration file located at /etc/updated.conf.
