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.
Answer:

Step-by-step explanation:
He will be charged $7.50 for 3 months, which is a total of 7.5 * 3 = $22.50.

305 - 22.5 = 282.5
The answer is therefore $282.50.
