Can the sum of squared deviation have a value of less than zero?
No. The square of a number is always positive, so the sum of several of them must also be positive.
In any distribution is the sum of the squared deviations from the mean always equal to zero?
No. It cannot be. Remember that when you square a negative number it becomes a positive number. Thus all squared deviations are positive and their sum must be positive.
Example for Quantity must be positive integer?
So there are two things we need. One, the number must be an integer, and two the number must be positive.Here are some examples.If you number the questions on a test, they will be positive integers/If you look at the number of people who read the answer to this question it must be a positive integer. I already read it so it can't be 0The number of people in the world is a positive integer.
Can a natural and a whole number be negative?
no a natural number must be positive
Is there a general rule that you must always follow when multiplying or dividing an inequality by a negative value?
positive and positive are positive positive and negative are negative negative and negative is positive
How can you tell from a linear equation which direction it goes without graphing the equation?
You must find the slope, if it is positive, then the line is always increasing. If it is negative, then the line is always decreasing.
Explain Why the product of two nonzero absolute values is always a positive number?
The absolute value of a number is its distance from zero on the number line, so it is always non-negative. When you multiply two nonzero absolute values, you are essentially multiplying two non-negative numbers together. In multiplication, a positive number multiplied by a positive number always results in a positive number, hence the product of two nonzero absolute values is always positive.
When solving inequalities using multiplication explain the difference between multiplying each side of the equation by a positive number and multiplying each side of the equation by a negative number?
When you multiply both sides by a negative number the inequality must be flipped over. You do not do that when multiplying by a positive number.

What is the first rule in accounting?
The equation must be ALWAYS equal.
Does negative n always equal a negative number?
No it doesn't. If the n is a negative number, it would equal a positive number. For example: -n=6 n must be -6 because a negative times negative equals positive.
Why can't you factor negative radical numbers?
You cannot factor negative radical numbers because the square of a number must always be positive. A negative number multiplied by a negative number produces a positive number. So, it is impossible to have a negative radical.
What are two things a number sentence must have?
an answer and an equation .

What particles must have an equal number on both sides of a chemical equation?
In a balanced chemical equation, the number of each type of atom (represented by its chemical symbol) must be the same on both sides of the equation. This ensures that mass is conserved and the chemical equation is balanced.
What can never be changed when balancing an equation?
The number and type of atoms must always remain the same on both sides of the equation when balancing a chemical equation. This requirement is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
