The standard deviation is the square root of the variance
so if the variance is 196, then the standard deviation is the sqrt of 196, which is 14
I would think 14 bc 8 units is smaller and 22 and 36 are two big
I'm assuming that y2 means y^2 or y squared. In that case, your factors will be (6y+1) and (6y-1).
For this case we have the following system of equations:

We multiply the second equation by -5:

Now we add the equations:

We find the value of the variable "y":

THE solution is: (-6, -3)
Answer:
(-6, -3)
