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).

One way is to move the 4 to other side so it would be x = 13 - 4 and that's x = 9
Answer: y = (1/7) x - 2
Step-by-step explanation:
The slope-intercept form of an equation is y = mx + b, where m is the slope and b is the y-intercept.
The slope of an equation is the change in y over the change in x.
We can see from the image that every time the line increases by 1 in the rise (y), it increases by 7 in the run (x).
Therefore, the slope is 1/7.
The y-intercept of a line is the point at which it intercepts the y-axis.
From the image, we can see that it intersects at the point (0,-2)
Therefore, the slope-intercept form is y = (1/7) x - 2
The answer is D. No
A sequence is considered arithmetic if it has a contant defference between each numbers.
Let's analyze the sequence above:
13 (+7) 20 (-3) 17 (+17) 34
Since the difference is not constant, we couldn't consider the sequence as arithmetic.

Answer:
a. 1.88495559215 radians
b. 5.23598775598 radians
c. 1.57079632679 radians
d. 4.93678845564 radians
Step-by-step explanation:
You want the coefficient of pi to be between 0 and 2. That is, you want its value modulo 2--the remainder from division by 2.
a. 13/5 = 2.6; 2.6 mod 2 = 0.6. 0.6π ≈ 1.88495559215 (as you know)
b. -13/3 = -4 1/3; -4 1/3 mod 2 = 1 2/3*. 5/3π ≈ 5.23598775598
c. 57/2 = 28.5; 28.5 mod 2 = 0.5. 0.5π ≈ 1.57079632679
d. 11/7 = 1 4/7. 11/7π ≈ 4.93678845564
All angles are in radians.

* My calculator gives the value of -4 1/3 mod 2 as -1/3. We want the positive value, so must add 2 to this. The attachment shows Desmos is smarter than my calculator.
