Hello!
If there is a relationship between dependent and independent variables represented in a scatterplot, <span>The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.
The independent variable is the one that influences the dependent variable. If there is a relationship between them, it doesn't matter the direction of the points in the scatterplot, but the correlation coefficient.
If the points go up from left to right, the correlation is called direct correlation (increasing the value of the independent variable will increase the value of the dependent variable).
If the points go down from left to right, the correlation is called inverse correlation (increasing the value of the independent variable will decrease the value of the dependent variable)
Have a nice day!</span>
Let x denote the length of the side of the garden which is covered fenced by a shed, and
be the width of the garden.
The perimeter of a rectangle is given by 2(length + width)
i.e.
which gives:
For the area to be maximum, the differentiation of A with respect to x must be equal to 0.
i.e.
Therefore, the maximum area of the garden enclosed is given by
I = PRT
Replace the letters with the given numbers:
350 = 700 * 0.10 * T
Simplify:
350 = 70 * T
Divide both sides by 70 to find T:
T = 350 / 70
T = 5 years
