Answer:

The answer to your question is Perimeter = 64 ft

Step-by-step explanation:

Data

width = 16 ft

length = width + 4 ft

Perimeter = ?

Which correlation coefficient corresponds to the best-fit line that most closely models it’s set of data. A. -0.87, B. -0.15. C.
ikadub [295]

Answer:

A. -0.87

Step-by-step explanation:

The correlation coefficient is a measure of the strength and nature of the linear relationship between two variables, one dependent and one independent. This coefficient takes values between -1 and 1, indicating with its sign whether the relationship is direct or inverse between the variables involved and with its absolute value indicates the strength of the linear relationship between them. A coefficient with absolute value close to 1 indicates great strength and better fit.

Conclusion: The best coefficient, of the propuetso in the problem, is that of -0.87, which indicates a strong relationship between the variables, a good fit and an inverse relationship between them.
