What else can I help you with?
What is y times -z?
-zy or y(-z) and viceversa or y x -z and viceversa
Does a positive minus a negative equal a positive?
Yes, if [x-(-y)=z] then it can be turned into [x+y=z] because the two negatives cancel each other out, causing you to be left with the opposite, a positive of plus sign.
What happens when you subtract a negative from a negative?
A large negative number. For example: -5-4=-9 You take the negative of the sum of the absolute values: -x-z = -(|-x|+|-z|) = -(x+z) As to what actually happens - some really rather abstract things to do with discrete mathematics.
In which direction does the x-axis run?
Generally the x-axis is displayed on a 2-dimensional Cartesian Coordinate system running horizontally (left to right - for negative to positive values of x) In a 3-D graph, the x-axis is usually shown running diagonally from upper right to lower left (for negative to positive values of x) . In a 3-D graph, the y-axis is the one running horizontally and the z-axis is vertical.
What does z equal in this equation 16-Z equals 34?
-18
Does a negative z score yield a negative probability value?
no, z score can be negative but a probability is a always positive between 0 and 1.
How do you interpret a negative z- score?
A negative z-score indicates that the observed value (or statistic) was below the mean. In non-directional tests, a negative z-score is just as likely as a positive one.
How do you find probabilty of negative z score?
Let z be positive so that -z is the negative z score for which you want the probability. Pr(Z < -z) = Pr(Z > z) = 1 - Pr(Z < z).
What is measured by the sign of a z-score?
The sign of the z score is negative if the observation was below the mean and positive if it was greater.
How do you change a negative z score to a decimal?
In the same way that you would convert a positive z-score. Only leave a negative sign in front of it.
Can a negative z score be greater than a positive z score?
Assume the z-score is relative to zero score. In simple terms, assume that we have 0 < z < z0, where z0 is the arbitrary value. Then, a negative z-score can be greater than a positive z-score (yes). How? Determine the probability of P(-2 < z < 0) and P(0 < z < 1). Then, by checking the z-value table, you should get: P(-2 < z < 0) ≈ 0.47725 P(0 < z < 1) ≈ 0.341345
Does anyone know any positive and negative character traits that start with the letter z and that start with the letter k too?
Positive Z: zealous, zestful. Negative Z: ??? Positive K: Kind, keen Negative K: kooky(?)
Why does a negative z score produce positive results?
well why can't pigs fly? same thing!
Is a negative z score always an indicator that the raw score is below the mean?
Yes.z = (raw score - mean)/standard error.Since the standard error is positive, z < 0 => (raw score - mean) < 0 => raw score < mean.
What is the meaning of a negative z score?
A negative z score is a value that is less than the mean value.
Does a positive raw score always result in a positive z score?
No.
What does a negative z-score mean?
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
