Answer:
- The dimensions of rectangle are 12 m and 4.5 m
Step-by-step explanation:
Given that, The length of a rectangle is 3 m more than twice the width, and the area of the rectangle is 54 m²
Let's assume width of rectangle be x m and length be 3 + 2x m respectively. To find the dimensions of the rectangle we will use the formula of Perimeter of rectangle

Substituting values in above formula:









Hence,
- Length of rectangle = 3 + 2x = 3 + 2(4.5) = 12 m
- Width of the rectangle = x = 4.5m

Answer:
C.) y variable
Step-by-step explanation:
In simple linear regression :
The dependent variable is the output variable = y variable
The simple linear regression is modeled using the general formula :
y = mx + c
Where;
y = output variable or dependent variable or predicted variable
m = gradient or slope of the regression line
x = input variable or independent variable or predictor variable
c = intercept ; where regression line crosses the y axis.
