Instructions: The last line of each example gives the reference to the line or lines needed for its derivation. You are to determine the correct rule of inference. Reference: Ref 8-1 1. ( R v Q ) ≡ S2. [( R v Q ) ⊃ S] · [S ⊃ ( R v Q )]              1, ___

Vocabulary: The minimum acceptable rate of return on an investment, often the company’s cost of capital.

Showing your work on a sheet of paper, derive the stated conclusion from the stated premises.   Indicate the logical function used in each step and the lines from which each new statement  is derived: G ͻ [~ O ͻ (G ͻ D)] O v G ~ O                         /  D

Instructions: The last line of each example gives the reference to the line or lines needed for its derivation. You are to determine the correct rule of inference. Reference: Ref 8-1 1. P ⊃ S2. ( R ⊃ S ) v ( R ⊃ Q )3. ( P ⊃ S ) · [ ( R ⊃ S ) v ( R ⊃ Q ) ]           1, 2, ___

Instructions: Determine the correct rule of inference for each step of the following completed proofs. Reference: Proof 3 Line 4:

Chromosomes regulating most body characteristics.

Instructions: The last line of each example gives the reference to the line or lines needed for its derivation. You are to determine the correct rule of inference. Reference: Ref 8-1 1. ( T v S ) ⊃ Q2. ~ ( T v S ) v Q                1, ___

It sometimes surprises folks that propositional logic treats a conditional statement as true when the antecedent is false.   Giving an example, explain why this is the case.

Instructions: For each of the following proofs, either the justification for a derived line has been omitted or else the derivation has been omitted. Choose the correct answer for each question. Reference: Proof 9 The derivation in line 4 is:

How does heat affect the viscosity and elastic properties of connective tissue that has been injured or immobilized?
