<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a measure of how similar two datasets are acting.

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated.

One data increases and other data starts to decrease in the opposite direction.

When the correlation coefficient comes out below 0, values are negatively correlated.

The correlation shown by the graph is negative.

From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).

Ashley has a sprinkler that has several varieties of coverage. The quarter circle sprinkler head sprays water a distance of up t
alukav5142 [94]

Answer:

314 square feet

Step-by-step explanation:

we know that

The area that will be covered by the spray of the quarter-circle sprinkler head, is equal to the area of a quarter circle with radius of 20 feet

so

The area of a quarter circle is

A=\frac{1}{4}\pi r^{2}

we have

r=20\ ft

\pi =3.14

substitute

A=\frac{1}{4}(3.14)(20)^{2}=314\ ft^2
