Answer:

  (d)  -√((2+√2)/(2-√2))

Step-by-step explanation:

5π/8 is a 2nd-quadrant angle whose reference angle is greater than π/4. This means the tangent is negative with a magnitude greater than 1. The only reasonable choice is ...

  \displaystyle -\sqrt{\frac{2+\sqrt{2}}{2-\sqrt{2}}}

_____

<em>Additional comment</em>

This simplifies to -(1+√2). Your calculator can verify the choice for you.

By definition, when a test or technique measures what it intends to, it is a. valid. b. reliable. c. significant. d. generalizab
SOVA2 [1]

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).
