Step-by-step explanation:
Use Pythagorean theorem:
c² = a² + b²
Here, c = 42 and a = 31.
42² = 31² + b²
b = √803
b ≈ 28.3
It’s interval. It will be right.
Answer:
B) 0.9, 0.45, -0.77, -0.95
Explanation:
The correlation coefficient is a statistical measure that indicates the strength of the relationship between two variables. The value usually ranges from -1 to 1 where:
• 1 indicates a strong positive relationship.
,
• -1 indicates a strong negative relationship.
,
• A result of 0 indicates no relationship at all.
Therefore, the given correlation coefficients classified from the strongest to the weakest is:

The correct choice is B.
Answer:
