 <span>P[ actually defective & shown as defective] = 98% of 0.08% = 0.0784% 
P[ok & shown as defective] = 2% of 99.92% = 1.9984% 

P[actually defective | shown as defective] = 0.0784/(0.0784+1.9984) = 3.775% <-------</span>

A circular cardboard piece is needed for the base of a volcano model. The volcano is 46 centimeters tall and has a volume of 800
Alenkinab [10]
For this case we can model the problem as a cylinder.
 The volume of a cylinder is given by:
 V = Ab * h&#10;
 Where,
 Ab: base area
 h: cylinder height
 Substituting values in the equation we have:
 800 = Ab * 46&#10;
 From here, we can clear the area of the base
 Answer:
 
An equation that can be used to find the area of the circular base is:
 
800 = Ab * 46
