Answer:
A. r = -0.93
Step-by-step explanation:
First, if there is a negative correlation, the correlation coefficient will be negative.
This eliminates answer choices C and D, which are positive.
If there is a strong correlation, the correlation coefficient will be closer to 1, or -1 (since the correlation is negative).
Since -0.93 is closer than -0.23 to 1, it has a stronger correlation.
So, the correct answer is A. r = -0.93
Answer:
12.6
Step-by-step explanation:
We can start by finding the area of the rectangle
13x4=52
Now the semicircles, the diameter of the circle is 4, so the radius is 2 to find the area we do
pi x 2=6.3
6.28^2=39.4
since there are two circles we can just add them together instead of dividing the answer above by 2, now we can subtract this from 52
52-39.4=12.6
