The formula to calculate the z-score of a certain value is:
z = (x - (mean))/(standard deviation)
In this example, the x-value is 450, the S.D. is 100, and the mean is 500.
So, substitute these values into the formula.
z = (450-(500))/100
z=-50/100
z=-0.5
Therefore, the z-score is -0.5.
Answer:
( 3u +12) / (v^2+4)
Step-by-step explanation:
(-u+3) / (v^2+4) + ( 4u+9)/( v^2+4)
Since the denominators are the same, we can add the numerators
((-u+3) + ( 4u+9)) /( v^2+4)
Combine like terms
( 3u +12) / (v^2+4)
The angle is 3 and 1 diameter
As you already know, to get the inverse of any expression, we start off by doing a switch on the variables, and then we solve for "y".
Answer:
Answer A- "The system of equations has one solution." :)
Step-by-step explanation:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. ... If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
Hope this helps! <3
