2 answers:
Answer:
Option A is correct
Step-by-step explanation:
Domain is the set of all input values ( i,e x-values) where function is defined.
In the given figure:
Input values are:
From top to bottom:
-3, 2, -5, 1, 6
Now, sort them to get:
-5, -3, 1, 2, 6
by definition of domain:
Therefore, the domain of the function is:

True
Step-by-step explanation:
Z-score may be defined as a position of the raw score in regard to the distance from its mean when it is measured in the units of standard deviation. Z-score is considered as positive, when the values is above the mean. And when it is below the mean, it is considered as negative.
Another name of a z-score is standard score. Z-score can be measured using the relation :
where, z = z-score
x = raw score
μ = population mean
σ = population standard deviation
Thus from the formula we can see how many standard deviation the score is from a men of the distribution by looking at the corresponding z-score.
