Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

Which of these square numbers have exactly 3 factors 1 2 4 8 16?
-- 2 and 8 are not squares.
-- The only factor of ' 1 ' is ' 1 '.
-- The factors of 4 are 1, 2, and 4.
-- The factors of 16 are 1, 2, 4, 8, and 16.
So I guess the number you're looking for is ' 4 '.
Who could you find the numbers of ways to order 4 students for a picture?

The number of ways to arrange them is (4 x 3 x 2) = 24 .
Who is known for his definition of irrational numbers?
Hippasus, a Pythagorean philosopher is believed to have proven the existence of numbers that are not rational. However, this is not quite the same as "known for". Many (most?) mathematicians would not know who Hippasus was or what he did.
What is the estimation of 7950?
It is not clear why you would want to estimate a number when you know the exact value! One approximation is 8000.
Is the number of a product to be manufactured a random number?
Usually not. The manufacturer plans how many units to produce and then needs to ensure that the company has the correct number of components, the correct amount of labour input and so on.
What are the numbers for the composite number 100?
4, 10, 20, 25, 50, 100 are the composite factors of 100.
When a fixed precision binary number is used to hold only positive values it said?
I'm not sure what you are asking for, but I know this. If you have a computer register that is used to hold integers, one bit is used for the sign. If the contents of the register are interpreted as non-negative integers, you don't need a sign bit, so you can use it for numbers that are twice as big. For example, if the register is 16 bits long, if it is used for signed integers, it can hold numbers from -215 to 215 - 1, which is to say -32,768 to 32,767. If the 16 bits are interpreted as a nun-negative integer, you get 0 to 65,535. If you mean strictly positive (excluding 0), then the register with all 16 bits 0 could be interpreted as 65,536, so the range would be 1 to 65,536. I hope that answers your question.
What is the opposite of real numbers?
An imaginary number such as the square root of any negative number.
Why can't you change a percent to a fraction?
You can. One quarter equals 25 %. One half is 50%. One whole (object) is 100% of that object or amount.
One third is 0.33, the three being repeated and called a repeating decimal.
If you want to change 16% into a fraction, it becomes 16/100 and that reduces to
4/25, and so that is the fraction version.
