Answer:
Option C) Quadratic regression model
Step-by-step explanation:
Quadratic regression model
- It is regression model in which states a non-linear relationship between the independent and dependent variables.
- It includes the dependent variable and the square of the independent variable.
where x is the independent variable and 
is the dependent variable.
- It is also referred to as second-order polynomial model.
- It is used when the data shape resembles to a parabola.
Thus, the correct answer is
Option C) Quadratic regression model
Answer:
$0.84
Step-by-step explanation:
120.96/144= 0.84
Answer:
5cm wide, 10cm long.
Step-by-step explanation:
I came to this answer by looking for common factors between 50 and 5, and I found 10.
5cm + 5cm = 10cm, so it works.
To confirm this, I multiplied 5 and 10 and got 50cm (squared) which works.
The length and width of the rectangle is 2√5m and √5m respectively
<h3>Volume of a rectangle</h3>
The formula for calculating the volume of a rectangle is expressed as:
V = lw
where
l is the length
w is the width
h is the height
If base is twice its width, then l = 2w
Substitute
10 = w(2w)
10 = 2w²
5 = w²
w = √5 m
Since l = 2w
l = 2√5m
Hence the length and width of the rectangle is 2√5m and √5m respectively
