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:
4.6
Step-by-step explanation:
Formula: Range = highest value - lowest value
Step 1: List all the data in ascending order
1.8, 2.4, 3.5, 4.9, 5.2, 6.4
Step 2: Identify the lowest and highest number
Lowest number : 1.8
Highest number : 6.4
Step 3 : Substitute the values in the formula
Range = highest value - lowest value
6.4 - 1.8 = 4.6
!!
a. vertical angles are congruent
b. congruence of angles is transitive
c. if two lines are cut by a transversal such that alternate interior angles are congruent, then the lines are parallel
Answer:
The 4th picture will be the correct one.
Step-by-step explanation:
The first picture shows the graph of f(x) and in the options there are pictures of graph of g(x) = f(x) -1
So, it is clear from the equation of the functions that the graph of f(x) and g(x) will be similar but the the y value in g(x) will be 1 less than the y value in f(x) corresponding to a certain x value.
So, the graph will translate down by 1 unit.
Therefore, the 4th picture will be the correct one.
Answer:
Step-by-step explanation:
we have to find if the series have a constant of proportionality by dividing the value of y by each value of x
1)
100 : 2 = 50
200 : 4 = 50
300 : 6 = 50
400 : 8 = 50
ok = y
2)
0.60 : 4 = 0.15
1.20 : 8 = 0.15
1.44 : 12 = 0.12
no = n
3)
0.15 : 1 = 0.15
0.3 : 2 = 0.15
0.45 : 3 = 0.15
0.6 : 4 = 0.15
ok = y
