By definition, when a test or technique measures what it intends to, it is valid.
The answer is option A.
The criterion-related validity of a take-a-look is measured by the validity coefficient. Its miles said as a number between zero and 1.00 that indicates the significance of the relationship, "r," among the take a look at and a measure of task overall performance (criterion).
Reliability and validity are both approximately how nicely a technique measures something: Reliability refers to the consistency of a measure (whether or not the consequences can be reproduced below identical situations).
Validity refers back to the accuracy of a measure (whether or not the results really do constitute what they may be speculated to a degree).

Hey there!!
If we look at the diagram closely, we will see that the triangle is a right angled triangle.
We figured out two angles, 60 and 90.
As the total sum of the angles in a triangle is 180, the missing angle would be ...
... 180 - ( 90 + 60 )
... 180 - 150
... 30
Hence, the angles of the triangle are - 30 , 60 and 90.
We could also apply the Pythagorean theorem to find the sides.
If we have a 30-60-90 triangle, the hypotenuse is 2x. The height is x and the base is √3x
Now, looking at the triangle, we know that the hypotenuse is 'x', base is 'y' and height is (15√2)/2
Hence, the base would be √3(height)
... √3(15√2)/2
... (15√6)/2
The hypotenuse = 2 ( 15√2/2)
... 15√2
Hence, the sides =
Hypotenuse - 15√2
Height = (15√2) / 2
Base = (15√6) / 2
<em>Hope my answer helps! </em>
<em>Happy thanksgiving! :)</em>
Answer: 90 degrees X=7 X=5 3,3,8 all in order but i couldn't solve the one with the measure lines
Your answer is 16 because your adding 1, then 2, then 3, than 4, than you have the mystery box, which you add 5, and you get 16
Glad I could help, and good luck! :)
