The mean would be negative, but standard deviation is always positive.
That is false. A negative times a negative is always a positive. Since absolute numbers are always positive if you make it negative that is not correct.
This is not strictly true, because an absolute value, and hence the product of two absolute values can be zero. It is, therefore true to say that the product of two absolute values is always non-negative. An absolute value of a number is, by definition, non-negative. And by the definition of multiplication, the product of two non-negative numbers in non-negative.
No. A negative plus a negative will always be negative. Adding negatives just makes them more negative, just like adding positives makes them more positive.If you're thinking of multiplication, then the answer is yes. Like signs result in positive values. Opposite signs result in negative values.

No. Probability values always have to be positive.
No, absolute values are always positive.

What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
The absolute value is the distance from 0 on the number line. -5 is 5 away from 0. You cannot have a negative distance, therefore you cannot have a negative absolute value. Absolute values are not ALWAYS positive because absolute values can be zero as well. Zero is not positive nor negative.
Some negative values in Filipino culture include "hiya" (shame), which can prevent open communication and honesty, and "utang na loob" (debt of gratitude), which can lead to manipulation or indebtedness. Also, "pakikisama" (need to get along) can sometimes prioritize group harmony over individual needs.
A sentinel loop is a loop that iterates over a series of values until a special "sentinel" value is encountered. For instance, when iterating over the characters in a string, the null-terminator acts as the sentinel value, indicating that the end of the string has been reached. Sentinel loops typically have the following form: while( get_value(value) != sentinel ) { // do something with value... }
The additive opposite is negative 8 (-8). Absolute values are always positive numbers.
