Yes
There are a few other factors, but yes, it's safe.
yes
no it is not
Yes. I have done it more than once.
Quality control and proof of accuracy, to weed out contaminants or bias.
yes because if you use the vertical line test it will not cross it more than once.
Mod Loader is the only mod that will allow your client to run more than one mod at once. It is very safe!
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
Yes & no. You can, actually, get mono more than once. Although not many people get it twice, you can & people do, so be safe regardless.
To make sure that the test results are the same and can conclude the result of the experiment will come up 100% of the time.
No. Use the vertical line test along the Y axis and if the line is crossed more than once, you know that it isn't a function.
Horizonatal line test is a test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one. A one-to-one function is a function where every element of the range correspons to exactly one element of the domain. Vertical line test is a test used to determine if a function is a function or relation. If you can put a vertical line through graph and it only hits the graph once, then it is a function. If it hits more than once, then it is a relation.
