E is greater cause it starts of adding at 4 and ends of adding at 102.
Answer:
a) Sample co-variance = -1.5
b) Sample correlation = -0.4404152
c) Weak negative relationship between X and Y.
Step-by-step explanation:
a) by sample co-variance = sum ((x - xbar)* (y-ybar)/n-1
#.... use the following program in R
x = c(7,8, 5, 3, 9)
y = c(7,5,9,7,7)
sv = sum((x-mean(x))*(y-mean(y)))/4
cor(x,y)

Hello!</h2>
The answer is:
The equation of the given circle is:

<h2>
Why?</h2>
The equation of a circle is given by the following equation:

We are given the center point (4,-5) and the radius.
So,
Where:

Then, substituting into the circle equation, we have:


Hence, the simplified equation of the circle is:

Have a nice day!
