Answer:
C
Step-by-step explanation:
Exponential decay should be in this format A = Ao × e^(-kt)
Hello!
As we can see, our a value, which would be the coefficient of
, which determines our slope, is negative, meaning that this whole line is negative.
Furthermore, the correlation can be determined using the r value of the linear regression, which is around -0.9.
If the r value of the linear regression is close to 1 or -1, let's say around |r| > 0.8, then we can consider the regression a strong correlation, meaning that this is a strong negative correlation, which is answer choice A.
0=40+3x
0=120x
Calculate the product
0=120x
Swap sides of the equation
120x=0
Divide both sides
X=0
Answer:
the mean deviation is 1.68
