It's c because. 80 divided. by 2 equals 40 then add 27 that equals 67
Step-by-step explanation:
To check out how efficient or accurate a model is, we use the akaike information criterion or the Bayesian. If the AIC or BIC are lower, then this model would be better. They are also used to control for model complexity
Akaike information criterion = 2k-2ln where k is the number of parameter. A higher k gives a higher AIC.
In the real world complex models are discouraged and avoided since
1. They cause data to be over fitted and can capture noise and information from this data.
2. They are complex and therefore difficult to interpret
3. They consume a lot of time and computing them has several inefficiencies.
Using these two as measure of performance, we can select optimal choice of independent variable.
With forward/backward regression, we are able to put new variables in the model or remove from it. The best is the one with lowest AIC.

Answer:
The answer to your question is Area = 37500 ft²
Step-by-step explanation:
Data
lawn 1 lawn 2
width = 550 ft width = 250 ft
Area = 181500 ft² Area = ?
Process
1.- Find the length of lawn 1
Area = length x width
-solve for length
length = Area/width
-Substitution
length = 181 500 ft²/ 550
-result
length = 330 ft
2.- Find the length of lawn 1 using ratios and proportions
550 : 330 :: 250 : x
x = (250 x 330) / 550
x = 150 ft
3.- Find the area of lawn 2
-Substitution
Area = 250 x 150
-Result
Area = 37500 ft²
P=20,000÷(1+0.085÷12)^(12×5)
P=13,094.999
