Answer:
(A)Simple First Order Model with Two Predictor Variables.
Step-by-step explanation:
A multiple linear regression model with k predictor variables X₁, X₂, ..., Xₖ and a response Y, can be written as:
y = βₒ + β₁x₁ + β₂x₂ + ··· βₖxₖ + ∈.
Where:
x₁ , x₂,...xₖ are the predictor variables.
βₒ ,β₁, β₂ ··· βₖ are the Regression Coefficients.
and ∈ are the residual terms of the model
Multiple regression models describe how a single response variable y depends linearly on a number of predictor variables x.
The model:
y = βₒ + β₁x₁ + β₂x₂ + ∈ has two predictor variables. It is also of first order since there is no quadratic term, therefore it is a Simple First Order Model with Two Predictor Variables.
Complete question:
A store sells packages of batteries. The package with the best deal has the highest ratio of number of batteries to total cost.
Packages of Batteries
Number of Batteries
Total Cost
3
$8
5
$8
12
$24
14
$24
Which package offers the best deal?
3 for $8
5 for $8
12 for $24
14 for $24
Answer:
5 for $8
Step-by-step explanation:
Given:
3 batteries sell for $8
5 batteries sell for $8
12 batteries sell for $24
14 batteries sell for $24
To find the package that offers the best deal, find the cost of each battery by dividing each total cost by the number of the batteries. The package with the lowest will be the best package.
Thus:
Package 1:
Package 2:
Package 3:
Package 1:
The best package here is package 2 where 5 batteries sell for $8, because the cost of each battery here is significantly lower than the cost of each battery in other packages.
The domain and the range of a graph are the set of input and output values on the graph
- The domain of the graph is [-3,2)
- The range of the graph is (-5,4)
<h3>How to determine the domain</h3>
On the graph, the x values starts at x = -3 (with a closed circle), and it ends at x = 2 (with an open circle)
This means that, the domain of the graph is [-3,2)
<h3>How to determine the domain</h3>
On the graph, the y values starts at y = -5, and it ends at y = 4 (with an open circle)
This means that, the range of the graph is (-5,4)

Answer:
The answer is C.
Step-by-step explanation:
The first line's slope is 2x and it y-intercept is 4. The second line's slope is simple 1x or just x (they are both the same).
