Answer:C. Systematic Sampling
Explanation:
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size.
Systematic sampling involves selecting items from an ordered population using a skip or sampling interval. The use of systematic sampling is more appropriate compared to simple random sampling when a project's budget is tight and requires simplicity in execution and understanding the results of a study.
Explanation:
This is because the SEO might not be able to access the media items wherever they are, or they could be deleted, or the media items may not be compatible with the SEO. It could also help to have alternatives for accessibility purposes. Therefore, it is important for the SEO to have alternatives to display incase a media item is unable to display for whatever reason.
Answer:
There could be a collision if a hidden node problem occurs.
Explanation:
CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.
If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.
Answer:
The answer to this question is the option "A".
Explanation:
In the given c++ program the compile-time error occurs in line number 8. In this program if block is used as an integer variable for checking condition that is number is greater then equal 0 and less then equal to 100 this is wrong.
So, the correct code for check if the block condition can be given as:
if (number>=0 && number<=100)
If we use this code in the if block section then the output of the question is passed.
