Answer:
For the first one I believe it is 90
Step-by-step explanation:
All I did to solve this was do 180 which is the diameter and divide by 2
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.
39 and 36. both of them rounded to the nearest 10 is 30
Bananas are $0.49 per pound, and you want to buy 5.5 pounds of bananas.
0.49 x 5.5 = 2.695 <span>≈ 2.70

So the final answer is 2.70 dollars for 5.5 pounds of bananas.
