Answer:
The answer is A. -2/7
Step-by-step explanation:
B.
because {1,1,3,5,8}
{2,2,4,6,9}
you're just counting the numbers after the one that was given to you.
Answer: Less than
Step-by-step explanation: A variables value is always 1.
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.
16 + 18 + 10 = 44
44 = x + 28
16 = x
x = 16
