Consider two observables: X and Y. The coefficient of correlation between these two variables is equal to 0.0147. The covariance these two variables is 0.515. The variance for X is equal to 49. Given this information. Compute the variance for Y.

other answer is correct. i had used the radius of the radius somehow. a website:

too hard the other guy did it

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
