CFA Level 1 - 101 Must Knows 368 Questions with Verified Answers Addition Rule of Probability - CORRECT ANSWER ADDITION: P(A or B) = P(A) + P(B) - P(AB) Roy's Safety First Criterion - CORRECT ANSWER Safety First Ratio = (E(R) - Rₜ) / σ Larger ratio is better If (Rₜ) is risk free rate, then it becomes Sharpe Ratio Sharpe Ratio - CORRECT ANSWER Sharpe Ratio = (E(R) - RFR) / σ Larger ratio is better If (Rt) is higher than RFR, then it becomes Safety First Ratio Centra...

________________ refers to scenarios for which a polymer will permanently flow overtime in response a constant applied stress. - ️️Viscoelastic Creep _____________________________ refers to scenarios for which the stress applied to a polymer must decay over time in order to maintain a constant strain. Otherwise, overtime, the polymer chains will slip and slide past one another in response to a constant applied load and the strain will increase (in magnitude) - ️️Viscoelastic Stress Rela...
