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...

ALARA - Answer-As Low As Reasonably Achievable DOT - Answer-a. Department of transportation governs the use of the nations transportation systems. Included in these regulations are rules defining radioactive materials and prescribing authorized modes for their transport. Dose Equivalent - Answer-a. (HT) means the product of the absorbed dose in tissue, quality factor, and all other necessary modifying factors at the location of interest. The units of dose equivalent are the rem and the Sv ...

Excitable CellsWhat is the charge of the resting membrane potential of all cells? Does the ICF or the ECF carry this charge? What is the average RMP value? Do most cells have an RMP that exists in a broad range or a narrow range? - correct answer All cells carry a negative resting membrane potential, and the ICF is negatively charged relative to the ECF. The average RMP value = -70mV. Most cells have an RMP that is small and w/in a narrow range. What types of cells are excitable cells? What i...
