Answer – C. (Convenience sampling)
The sampling method that is generally considered the weakest is convenience sampling. This is because in convenience sampling, there is usually no inclusion criteria identified prior to the selection of subjects. Convenience sampling involves getting participants wherever you can conveniently find them. Typically, the first available participants (or any other primary data source, as the case may be) will be used for the research without any additional requirements.Other names by which convenience sampling is known are: Incidental Sampling, Chunk Sampling, and Accidental Sampling.
Step-by-step explanation:
y=mx+b
y=-6x+b
3=-6(-1)+b
b=-3
y=-6x-3
So you want to cross multiply. then it would be 3x=25 then divide by 3 isolating x. x=25/3
Answer:
6 and 7
Step-by-step explanation:
x + y = 13
xy = 42
I just listed the two equations out and the answer just popped out. The trick to this is just thinking about two numbers that obviously both below 13 that add up to it. 6 and 7 is the solution.
913
<u> - 426 </u>
<u />487 would be your total but your question is how many times we would have to regroup, so.
<u />
First, you would have to borrow from the 1 because 3 is smaller then 6. Second, you would have to borrow from the 9 because you can't take 2 from 0. So there you would have to regroup twice to work this problem.
Hope that helps you. :-)
