If we make the days and ounces be in the ordered pair, the points are: (2, 39), (4, 33), (6, 27), and (8, 21). We may use linear regression from the calculator using the equation,
y = Ax + B
where A is the slope. The value of A from the linear regression is equal to -3.
Answer:
A. -22
hope this helps
have a good day :)
Step-by-step explanation:
Percent increase=increase/original converted to percent
increase=new-original=2.35-2.10=0.25
percent increase=0.25/2.10=0.11904=11.9%
