Answer: X= 25 degrees
Step-by-step explanation:
A triangle is 180 degrees.
115+40=165
180-165=25 degrees
X-27=-1
x represents unknown number
A tennis ball is a sphere
Volume of a sphere ===>
![v= \frac{4}{3} \pi r^3](https://tex.z-dn.net/?f=v%3D%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E3%20%20)
Plug in the given info

Turn 7/4 into a decimal by dividing it and then multiply from there and you get 1.75. Then you time 5.4 by 1.75 and you get 9.45
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.
