What must a subclass do if it inherits an abstract method?

Which keyword is used to implement an interface?

//what is the output? abstract class Animal { abstract void sound(); void eat() { System.out.println(“Eating”); }}class Dog extends Animal { void sound() { System.out.println(“Bark”); }}class Test { public static void main(String[] args) { Dog d = new Dog(); d.sound(); d.eat(); }}

Calculate net present value (NPV) for subcontractor A.

Suppose your BCWS for a project was $100,000 and ACWP is $80,000. Calculate the SPI.

In the above situation, what happens if one uses Monte Carlo simulation?

Calculate the expected monetary value (EMV) of this decision tree problem.

PART A Draw the AON network and solve it (perform FWD & BWD pass calculations + TF & FF). Based on your calculation: For activity D: its earliest start date is day [ES_D], its total float is [TF_D] days, and its latest finish date is day [LF_D]. For activity F:  its earliest start date is day [ES_F], its total float is [TF_F] days, and its latest finish date is day [LF_F]. For activity H: its earliest start date is day [ES_H], its total float is [TF_H] days, and its latest finish date is day [LF_H].

If BCWS=1200, BCWP=1100, and ACWP=1200, the project is [schedule] schedule and [budget] budget.
