Answer:

10 minutes

Which correlation coefficient could represent the relationship in the scatterpot. Beach visitors
adoni [48]

Answer:

A. 0.89.

Step-by-step explanation:

The value of correlation coefficient ranges from -1 to 1. Any value outside this range cannot possibly be correlation coefficient of a scatter plot representing relationship between two variables.

The scatter plot given shows a positive correlation between average daily temperatures and number of visitors, as the trend shows the two variables are moving in the same direction. As daily temperature increases, visitors also increases.

From the options given, the only plausible correlation that can represent this positive relationship is A. 0.89.

Ugo [173]

Answer:

36\:\mathrm{in^3}

Step-by-step explanation:

The area of a prism is given by the product of the base and the height. In this triangular prism, the area of the either base is:

A=\frac{1}{2}\cdot 3\cdot 4=6\:\mathrm{in^2}

The height is marked as 6 inches. Thus, the volume of the prism is:

\frac{1}{2}\cdot 3\cdot 4\cdot 6=\boxed{36\:\mathrm{in^3}}
