Part A
Correlation coefficient: -.99
This tells us that as time goes on (value of x increases) the area of the puddle goes down (value of y decreases)
Part B
y₂ - y₁
------- = slope
x₂ - x₁
9 - 15
--------
5 - 8
-6/-3 = 2
So the slope equals -2, regardless of the fact that we got 2 as an answer there, we know that it is a negative slope
Part C
The data represents causation because an increase in the value of x results in a decrease in the value of y, this shows an example of direct causation between x and y.
Step-by-step explanation:
I'm not sure if this correct or not
Answer: if you’re saying she received 75 calls the first evening then she would have received 10 more then that which is 85 on the third evening and 85x3 = 255 on the second evening.
So first evening 75
Second evening 255
Third evening 85
