The statement (A), statement (B), statement (D) are correct because the equation is y = 437.9x + 439.4

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

From the data given, we can calculate the correlation coefficient, slope of the line, and y-intercept.

r = 0.90

Since r is close to 1 shows a strong correlation.

Slope of the line of best fit = 437.9

Y-intercept of line of the best fit = 439.4(Refer to the attached picture)

The line will be:

y = 437.9x + 439.4

Thus, the statement (A), statement (B), statement (D) are correct because the equation is y = 437.9x + 439.4

A woman wants to build a rectangular garden. She plans to use a side of a shed for one side of the garden. She has 84 yd of fenc

Ivan

Let x denote the length of the side of the garden which is covered fenced by a shed, and $\frac{A}{x}$ be the width of the garden.

The perimeter of a rectangle is given by 2(length + width)
i.e. $2x + \frac{A}{x} = 84$
which gives:
$A = 84x - 2x^2$

For the area to be maximum, the differentiation of A with respect to x must be equal to 0.
i.e. $\frac{dA}{dx} =84-4x=0 \\ 4x=84 \\ x=21$

Therefore, the maximum area of the garden enclosed is given by
$84(21)-2(21)^2=1764-2(441)=1764-882=882 \, yd^2$
