Answer:
Solution set = {25}
Step-by-step explanation:
=>
Dividing both sides by -1
=>
Taking square on both sides
=> x = 25
<em><u>Solution set = {25}</u></em>
The r value is a number between -1 and +1.
For a negative value, the closer to -1 it would be a strong negative, if it is closer to 0, it would be a strong negative.
-0.31 is closer to 0 than -1, so it would have a strong negative association.
