Answer:
And the determination coeffcient is just the correlation coeffcient square and we got:
And rounded to the nearest tenth thousand would be 0.1521
Step-by-step explanation:
The correlation coefficient is a measure of variability and is given by this formula:
![r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bn%28%5Csum%20xy%29-%28%5Csum%20x%29%28%5Csum%20y%29%7D%7B%5Csqrt%7B%5Bn%5Csum%20x%5E2%20-%28%5Csum%20x%29%5E2%5D%5Bn%5Csum%20y%5E2%20-%28%5Csum%20y%29%5E2%5D%7D%7D)
For this case we have
And the determination coeffcient is just the correlation coeffcient square and we got:
And rounded to the nearest tenth thousand would be 0.1521
The ray that is opposite FH in the image given is: FE.
<h3>What is a Ray?</h3>
A ray is a straight line that starts from one end and extends infinitely towards the opposite end.
We are asked to find the ray that is opposite to FH. This means the ray opposite to FH will definitely start from point B and extends to the opposite direction.
Ray FE is opposite FH.

7+3 = 10 total marbles
1st pick = 7/10 for a red one
2nd pick = 6/9 reduces to 2/3 for a red one
3rd pick = 3/8 for a white one
7/10 x 2/3 =14/30 reduces to 7/15
7/15 x 3/8 = 21/120 reduces to 7/40
probability = 7/40
