A random sample of 10 subjects have weights with a standard deviation of 12.2778 kg. What is the variance of their weights? Be sure to include the appropriate units
with the result
Tho variance of the sample data is __
(Round to four decimal places as needed.)

it is not that hard all u have to do is plot the graph

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
