It is 7.5 because it’s quick maths
By checking to see if there is correlation, Sam is evaluating the criterion validity of the metric.
<h3>How to determine the measured parameter of the metric</h3>
From the question, we understand that Sam tests the metric to check for the presence or absence of correlation in the metric.
This, in other words means that Sam is checking the criterion validity of the metric.
Hence, the true statement is that Sam is evaluating the criterion validity of the metric.

Answer:
4 x 100 = 400
400 ÷100 = 4
B= 100

Answer:
20.5 degrees
Step-by-step explanation:
So when the arc is being made from two lines coming out from the center, the measure of the arc is the same as the angle of the lines.
So the measurement of 41 degrees for the arc is also the angle of line OB and line OC.
Now that center line is the diameter, which means it is 180 degrees
So you can find the angle of line OA and OB:
180 - 41 = 139
Then, to find x you need to recognize that OB and OA is actually the radius of the circle, which means they are the same length.
This makes it an isosceles triangle. So, the angle of OB and BA is the same as OB and BA. The measurement of all the angles in a truianbgle is 180 degrees, so to find the measurement of x, you need to subtract 139 from 180:
180-139 = 41
And then divide by two to find the remaining two angles:
41/2 = 20.5
and that is x :)
