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.

The phrase that would complete the proof is this:
Angle 2 is equal to Angle 4.
Vertical angles are angles formed when two lines intersect each other. The angles that are opposite each other are equal by a series of supplementary, complementary, and transitive property proofs.
74.25 minus 38.50 equals 35.75 then do 35.75 divided by 6.50 which is 5.5 so he worked 5 and a half hours
