Answer:
radius=6
Step-by-step explanation:
First subtract the x variable on both sides so on the first equation youll have -6y=8x+60 then divide 6 on all variables which means youll have y=8/6x+10 and in the second equation you do the same thing and youll have y=-5/6x-11.5
44 [minutes] * 8 [times as many as April] = 352 [minutes in April]
Answer:
$9 a hour.
Step-by-step explanation:
2 hours for 10 nights, In total felicity worked for 20 hours.
To hind the hourly rate you would take your number of hours worked ( 20)
and divide it by 180 to see how much felicity got paid for one hour.
<u>180 </u>
<u>20</u>
<u>After dividing you will get the answer 9.</u>

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.
