What does a minus 6 and a plus 6 equal to?
Zero
What does zero minus negative three equal?
"minus zero" is the same as plus zero in that it makes no difference to the sum. So the answer is -3.
What is x minus x equal to?
It is equal to zero.
Can the variance be zero?
Variance is standard deviation squared. If standard deviation can be zero then the variance can obviously be zero because zero squared is still zero. The standard deviation is equal to the sum of the squares of each data point in your data set minus the mean, all that over n. The idea is that if all of your data points are the same then the mean will be the same as every data point. If the mean is the equal to every data point then the square of each point minus the mean would be zero. All of the squared values added up would still be zero. And zero divided by n is still zero. In this case the standard deviation would be zero. Short story short: if all of the points in a data set are equal than the variance will be zero. Yes the variance can be zero.
What does 0 squared equal?
It equals 0. Zero times zero equals zero.
3x squared minus 3 equal zero?
x = 1
How do you solve minus 2x squared plus 10x minus 14 equal 0?
It can't be solved because the discriminant of this quadratic equation is less than zero
What is X squared plus 6x minus 55?
Without knowing what "x" is, we cannot say what the answer will be. And without knowing the answer, we cannot solve for "x". Set x at zero, for example. Zero squared is zero, plus 6 time zero which is zero, minus 55. Your answer is then -55. Set x at one, for example. One squared is one, plus 6 times 1 which is six, minus 55. Your answer is then -48. Etc.
What does a minus 6 and a plus 6 equal to?
Zero
What is the solution to x squared minus 6x plus 8 equal zero?
(x-2)(x-4) = 0 x = 2 or x = 4
Can you solve x squared minus six plus five equals zero?
X=1
What does zero minus negative three equal?
"minus zero" is the same as plus zero in that it makes no difference to the sum. So the answer is -3.
What is 25 squared minus 625?
zero
What is zero minus zero Does it equal orange?
Zero minus zero equals zero.
How do you factor z squared minus Z plus 16?
It can't be factored because its discriminant is less than zero.
What is six x squared plus seven x minus five equals zero?
x = 5 / 6squared + 7
What is two minus zero minus zero plus zero?
It Equals 2
