The answer is Perpendicular is the best describes the relationship between the line r and AM.
Answer:
C, 3
Step-by-step explanation:
By creating a best line of fit you can get the sets of points (16,50) and (12,40)
Using these to find the slope we can get 
-10/-4 is 2.5 The best approximation would be C, because if you round it up to the nearest number you would get 3.
The formula

, for n=1 becomes

.
Comparing

with

, we see that
P=900, and 1+r=1.185, which means that r=0.185.
r=0.185 can be written as 18.5%, as a percentage.
Answer: 18.5%
Step 1: 18x - 42 = 2
step 2: 18x = 44
Divide by 6... For part E, you should know every ingredient for 1 serving by then, so mu multiply by 10
