It is function a the answer
Answer: The z score that corresponds to the value x=22 is 0.4 .
Step-by-step explanation:
Given : A normal distribution has a mean 20 and standard deviation 5.
i.e. 

Let x be the random selected variable.
We know that to find the z-score corresponds to the value x is given by :-

For x = 22, we have

Hence, the z score that corresponds to the value x=22 is 0.4
3x+4=1
3x=-3
x=-1
Hope this helps!!!!
in this situation it would be the last one or d.
A translation of
units upwards and
units to the right is represented by the transformation

So, to translate 5 right and 7 down, we need

Now we just need to plug x=x-5 and y=y+7 in our equation (remember f(x)=y):

The answer is
