Answer:
A. 821.5 Square Yards
Step-by-step explanation:
30 x 30= 900
900 is the area for the whole park
To find the pool area you need to do pi times Radius squared
so 3.14 x 5 x 5
That equals 78.5 for the pool area.
So to find the grass area you need to subtract the pool area from the park
900 - 78.5 = 821.5 square yards!

Answer:
a positive correlation is when both variables move in the same direction. a negative correlation is when the variables move in opposite directions. no correlation is when the variables are not statistically related
Step-by-step explanation:
negative correlation example: As you climb the mountain (increase in height) it gets colder (decrease in temperature).
zero correlation example: the amount of apple juice drunk and level of intelligence
btw you have a good example of positive correlation :) it can also be when both variables decrease
