In exercise 5.10, we proved that f(y1,y2) = is a valid joint probability density function for y1, the amount of pollutant per sample collected above the stack without the cleaning device, and y2. the amount collected above the stack with the cleaner. are the amounts of pollutants collected with and without the cleaning device independent?

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

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
