Final answer:
The formula to evaluate if security procedures are effective is P > D + R. If the probability of success is higher than the combined probabilities of detection and response, then the security procedures can be considered effective.
Step-by-step explanation:
The formula to evaluate if security procedures are effective is represented by option a: P > D + R. This formula states that the probability of success, P, should be greater than the sum of the probability of detection, D, and the probability of response, R. In other words, if the probability of success is higher than the combined probabilities of detection and response, then the security procedures can be considered effective.
The formula for calculating the power dissipated in a resistor is P = IV. This formula is essential in understanding electrical circuits and is typically covered in high school or college-level mathematics.
The initial question about the formula to evaluate if security procedures are effective seems to be misplaced and does not align with the provided reference information. However, looking at the references provided, they relate to probability and power in the context of electrical circuits, which are mathematical concepts typically covered in high school or even college. For clarity, I'll provide an answer related to the power formula since it directly corresponds to one of the practice problems provided.
Practice Problems on Power in Resistors
The formula for the power dissipated in a resistor is given by P = IV, where 'P' stands for power, 'I' is the current through the resistor, and 'V' is the voltage drop across the resistor (practice problem 16c). This same relationship can also be expressed as P = I2R or P = V2/R, where 'R' is the resistance (discussion for d).
It's important to ensure that we are using the correct variables and units when applying these formulas to avoid errors in calculations. An understanding of electricity and circuits is crucial for solving these types of problems.
