The option fourth "There is a strong negative relationship between x and y" is correct.
<h3>What is correlation?</h3>
It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
The options are:
- There is no relationship between x and y.
- There is a weak negative relationship between x and y.
- There is a strong positive relationship between x and y.
- There is a strong negative relationship between x and y.
We have data:
x 7 8 9 10 11 12 13
y 13 10 7 6 5 3 0
The value of correlation r = -0.9847
As we know the value of r between -1 to +1
If r = 1 (perfect and positive correlation)
if r = -1 (perfect and negative correlation)
We have r = -0.9847
The value is near to -1 which means there is a strong negative relationship between x and y.
Thus, the option fourth "There is a strong negative relationship between x and y" is correct.

So you would first divide 1/4 by 2 to get 1/8 and then you would add 1/8 to 1/4 to get 3/8 ,since 1/4 is 2/8. 3/8 is eqivalent to 37.5%
Answer:
f = -4
Step-by-step explanation:
2f-8= -16
2f = -16+8
2f = -8
f = -8/2
f = -4
Domain are those values of x for which function is defined. f(x) is not defined at x = 3. Therefore Domain is
x∈ (⁻∞, +∞) - {3}
Answer:
23.04
