1.The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
2.How long should AB test last?
How long should AB test last?For you to get a representative sample and for your data to be accurate, experts recommend that you run your test for a minimum of one to two week. By doing so, you would have covered all the different days which visitors interact with your website.
3.in algebra all the variable or letter that do not have coefficient is equivalent to 1. so the value of y is 1.
4.A.D. comes from the Latin "anno Domini," which means "in the year of the Lord." A.D. applies to years following the birth of Jesus. Therefore, it's easy to assume that A.D. 1500 means 1,500 years after Jesus was born, but that's not strictly true because A.D. began at 1.
