Part A
Correlation coefficient: -.99
This tells us that as time goes on (value of x increases) the area of the puddle goes down (value of y decreases)
Part B
y₂ - y₁
------- = slope
x₂ - x₁
9 - 15
--------
5 - 8
-6/-3 = 2
So the slope equals -2, regardless of the fact that we got 2 as an answer there, we know that it is a negative slope
Part C
The data represents causation because an increase in the value of x results in a decrease in the value of y, this shows an example of direct causation between x and y.

Answer:
The radius of the circle is 9 in
Choice C is correct
Step-by-step explanation:
254.4696 square inches. Whats the radius of the circle (use pie=3.1416.
The area of a circle with radius r is given as;

We substitute the given area and the value of pi given to solve for the radius;
