Answer: its 12,000
Step-by-step explanation:
The correlation based on the computation is 0.97.
<h3>How to compute the value?</h3>
It should be noted that the question is that we should simply calculate the correlation which is r.
The correlation will be:
= Σ(x y) / (Σ(x²) × Σ(y²)
= 9627/✓(1118 × 87982)
= 9627 ✓98363876
= 9627/9917.86
= 0.97

Your equation or notation would be: 12(6+5)
Step-by-step explanation:
Given
y = x + 3.....equation 1
y = x - y
or y + y = x
or 2y = x
or y = x / 2......equation 2
Now
Putting equation 2 in equation 1
x / 2 = x + 3
x - x/2 = - 3
<u>2x</u><u> </u><u> </u><u>-</u><u> </u><u>x </u> = - 3
2
x / 2 = -3
x = - 6
Now
y = x/ 2
= - 6/2
= - 3
Hope this helps
