What is the standard deviation of the random variable X, "the number that
comes up on the die"?
O A. 2.291
O B. 1.708
O C. 3.5
O D. 14.028
E. 3.745

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

b, i believe, but not sure.

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

inverse property is the answer
