4 poundsx2times per day= 8 pounds
8 pounds x 4 horses=32 pounds
32 poundsx 3 days = 96 pounds
Answer:
63.59 (c)
Step-by-step explanation:
Formula: π
Plug in data:
9cm is diameter and a radius is half a diameter so the radius is 4.5cm.
π x 4.5^2 = 63.59cm^2
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.
