Answer:
Linear: greater than 2011
Quadratic: lesser than 2011
Cubic: lesser than 2011
Step-by-step explanation:
At x = 2
Linear regression equation:
y = -6777.54(2) + 110001.04
y = 96445.96
More than 2011
Quadratic: y = -251.10(2)² - 2760.02(2) + 98618.06
y = 92093.62
lesser than 2011
Cubic: y = -6.23(2)² - 101.67(2)² - 3747.49(2) + 100142.23
y = 92190.73
lesser than 2011
We don't know what the answer choices are!!
The answer would be 44,800 if you want to round the hundreds place
I would add them together to get 73
Step-wise I would add the ones column together to get 13, carry the one over then add the tens up to get 70 - your answer is 73
