Answer:
a)
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
b)
Now we can find the means for x and y like this:
So the line would be given by:
Step-by-step explanation:
Part a
The correlation coeffcient is given by this formula:
For our case we have this:
n=4
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
Part b
Where:
With these we can find the sums:
And the slope would be:
Now we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:

Answer:
The volume of given cone is 602.88 cube units
Step-by-step explanation:
<u>Formula:</u>
Volume of cone, V = πr²h
r - Radius of cone
h - height of cone
<u>To find the volume</u>
Here, r = 4 and h = 12
Volume V = πr²h
V = 3.14 *4²*12
V = 3.14*4*4*12
Volume V = 602.88
Therefore the volume of given cone is 602.88 cube units
