The formula for this type of question is z=x-u/y
z=-2 (z-value)
u = 27 (mean)
y = 4 (standard deviation)
Therefore -2=x-27/4
You now figure this out like a normal equation
4x-2=4 X x-27/4
-8+27= x-27+27
19=x
Therefore the data value of x is 19
The point (−3, 0) is on the x axis.
I know because the point show us that
X=-3 and y=0
That means that the point that we will graph is on the -3 of the x axis. We don’t have to worry about the y because it’s equal to 0.
Answer:
and 
Step-by-step explanation:
-equation 1
-equation 2
Solving the equation 1 to get the value of
To solve such type of equations that have two unknown variables, find the value of one variable in terms of the other from any one of the equation and put the value in the second equation which will give the value of both the variables
Solving Equation 2 to find x
equation 3
Putting this value of x in the equation 1
,
Putting the value of y in equation 3 to find the value of x
Answer:
see explanation
Step-by-step explanation:
Because division by zero is undefined
The number is -27 because 15 plus 12 is 27 snd you just add the negative
