<u>Answer-</u>
<em>A. strong negative correlation.</em>
<u>Solution-</u>
<u>Direction of a relationship</u>
- Positive- If one variable increases, the other tends to also increase. If one decreases, the other tends to also. It is represented by positive numbers(i.e 0 to 1).
-
Negative- If one variable increases, the other tends to decrease, and vice-versa. It is represented by negative numbers(i.e 0 to -1)
<u>Strength of a relationship</u>
- Perfect Relationship- When two variables are linearly related, the correlation coefficient is either 1 or -1. They are said to be perfectly linearly related, either positively or negatively.
- No relationship- When two variables have no relationship at all, their correlation is 0.
As in this case, correlation coefficient was found to be -0.91, which is negative and close to -1, so it is a strong negative correlation.
UGH I think I did this before but I totally forgot how to do it. Give me a minute to do some research and remember because I'm about 79% sure I know how to do this!

Answer:
V = 288.5 
Step-by-step explanation:
To find the volume of a cone, use this equation:

r = radius
h = height
We aren't given the height of the cone, just the length of the side. To find the height use the Pythagorean Theorem:

The value of 12.1 yds is the hypotenuse and the radius is the value of one of the legs. So, set it up like this:

Now, solve:
Distribute the square
Subtract 25 from 146.41

a = 11.01862
So, the height is equal to 11.01862 yds.
Now, we can plug everything into the volume equation:

Simplify (use calculator):
V = 288.5 
So, the volume of the cone is equal to 288.5
