X= -6
Y=-1
The x value is minus 6 and the y value is equal to minus 1
r value i.e Correlation between x value and y value = 0.769
=Standard deviation of the x-coordinate = 5.508
=Standard deviation of the y-coordinate = ?=k
Slope of line is given by formula
If slope of line is m, then
m =
m= 
Substitute the value of k, i.e Standard deviation of the y-coordinate and then you can get the slope of line to three decimal places.
Looks like a pretty regular system, no parallel lines. In fact the second equation is a vertical line as written; not sure if that's a typo. Either way,
Answer: EXACTLY ONE SOLUTION
Definitely, its volume is greater than the original cylinder. Hope it help!
Answer: The answer is 314.28 cm² (approx.).
Step-by-step explanation: Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm.
We need to find the area 'A' of the circular cross-section of the pipe.
Given, diameter of the circular section is

So, the radius of the circular cross-section will be

Therefore, cross-sectional area of the pipe is

Thus, the answer is 314.28 cm² (approx.).
