An operational definition can both define and measure the hypothetical construct. The hypothetical construct is also called psychological construct is an explanatory variable which cannot be directly observed. It is also a tool to understand someone’s behavior.

Answer:
C. Add 15 to both sides
Step-by-step explanation:
Given equation:
99x – 15 = 45
To solve:
<u>Step 1</u>: Add 15 to both sides:
⇒ 99x – 15 + 15 = 45 + 15
⇒ 99x = 60
<u>Step 2</u>: Divide both sides by 99:
⇒ 99x ÷ 99 = 60 ÷ 99
⇒ x = 60/99
⇒ x = 20/33
There's a strong negative association between the two variables.
