The chi-squared statistic is calculated by summing (O-E)2/E where E and O are the expected and observed values for some category, and the summation is carried out over all categories.
The expected number of observations for any category cannot be negative, and the numerators are squares so each element in the summation is non-negative. Consequently the sum is non-negative.

Can Km be a negative value?
No the Km can never be a negative value. The Km increases or decreases with temperature. An incorrect calculation can produce a negative value.
Why is the absolute value of a number never negative?
Because when you find the absolute value you're finding the distance a number is from zero without considering its sign (+ or -). You just have to make the number positive.
Does -3x have a positive or negative value?
It depends on what the value of x is. If x is a positive number, then it will be negative because a negative number multiplied by a positive number is negative. If x is a negative number, then it will be positive because the product of two negative numbers is always a positive number.
The absolute value of a number can never be negative true or false?
true (that's the whole point of absolute value)
What is negative 2 with the power of 4?

i don't know. i think very complicated.
Explain why the absolute value of a number is never a negative number?

An absolute value can never be a negative. An absolute value is just the distance the # is from the zero...so again for it to be negative thats not possible
Why is absolute value of a number never a negative?
If it had a sign it wouldn't be an absolute value, which is neither positive nor negative, merely absolute.Note that the absolute value of a number is non-negative by definition.For x < 0, |x| = -x (which is positive)For x ≥ 0, |x| = x (which is never negative)
