The answer is n= -1.
Hope this helps
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).

#SPJ4
1 1/2 + 1 1/2 & 1 3/4 + 1 1/4
Answer:
Highest to lowest the numbers would be (1/2)^2, (-1)^2, -1 2/5 Putting the "bar 4" somewhere
First we need the numbers exact value meaning
-1 2/5 = -1.4
(-1)^2 = -1
?4 = ?
(1/2)^2 = 0.25
Answer:
(3, 4)
Step-by-step explanation:
A function is a relation that maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs).
Such that a function can map each element of the domain into only one element of the range.
Then, if a "function" has:
f(x1) = y1
and
f(x1) = y2
It is mapping the input "x1" into two different outputs, then this is not a function.
Now, we know that the ordered pair (3, -4) is among the points on the graph of the function f(x)
(The first value is the input and the second one is the output)
Then the point that does not belong to the graph, is the point that has the same input and different output.
(3, 4)
Any of the other points could belong to the graph.
