Answer:
11860.22 rev/hour
Step-by-step explanation:
The diameter if a cylinder, d = 21.02 inches
Radius, r = 10.51 inches
or
r = 0.875 feet
The linear speed of a point on the cylinder's surface is 18.12 ft/sec.
We need to find the angular speed of the cylinder.
The relation between the linear speed and the angular speed is given by :
Where
is angular speed
or
So, the required angular speed of the cylinder is 11860.22 rev/hour.

Let us assume that even F represents fidelity and event S represents selectivity.
We have been given the probabilities:
P(S) = 0.72, P(F) = 0.59 and
We need to find the conditional probability that a system with high fidelity will also have high selectivity. We know the conditional probability formula:
Upon substituting the given values, we get:
