No. It is defined to be the positive square root of ((the sum squared deviation divided by (the number of observations less one))
No. There is no real number which multiplied by itself forms a negative number.A negative times a negative is a positive, and only a positive times a negative is a negative.However, in calculus there is an "imaginary value" (called i ) which represents the square root of -1.Square roots of larger negative numbers are represented by the square of the absolute value times i .
There must be some value otherwise nobody would do them. On that basis, the value must be positive.
It is the square of the original number. If the original number represents a length, then the square of the original number represents an area of a square with side equal to the original number.

None of "these" expressions represent anything!

√(a^2) That is |a| (the absolute value of a) Because if a is positive, a^2 is positive, and since √ is a positive square root, √(a^2) is a. If a is negative, a^2 is positive, and since √ is a positive square root, √(a^2) is -a. So if a is positive, √(a^2) is positive (which is a) If a is negative, √(a^2) is also positive (which is -a) So √(a^2) is |a| for every a.

No. Probability is always represented as a positive ratio/fraction/percent.
The square of negative iota will be the same as the square of positive iota (i.e. -1) because when a negative number is multiplied by a negative number, the answer is positive.

To solve equations with absolute values in them, square the absolute value and then take the square root. This works because the square of a negative number is positive, and the square root of that square is the abosolute value of the original number.
The answer will depend on what c represents. Furthermore, there probably is no value of c such that each expression is a perfect square - you will need different values of c for different trinomials.The answer will depend on what c represents.

A square can be as small or as large as you like. So, the square footage can have any positive value.
