Answer:
Z = 3
Step-by-step explanation:
In a normal distribution, the Z score that corresponds with a data point x is calculated using the formula;

For the case given, the z score will be;

To do this, simply add the 2 functions-as it says:
(2x+1) + (-3x+4)
2x+1-3x-4
-x-3
Your answer is -x-3
1,5, and 25. 1*25=25 and 5*5=25
<u>Question 1</u>
Since the x-coordinates are the same, the line is vertical. Therefore, the slope is undefined.
<u>Question 2</u>
Since the y-coordinates are the same, the line is horizontal. Therefore, the slope is zero.
