問題文
The platform must express how much of its monthly error budget has been consumed so far, given a recorded 30-day error ratio series and an objective of 99.9 percent. Which expression form does this?
選択肢
- Divide the recorded error ratio by the allowed error fraction expressed as a scalar, because a vector divided by a scalar applies the operation to every sample.
- Subtract the allowed error fraction from the recorded error ratio, because the difference is the amount of budget consumed beyond the objective.
- Compare the recorded error ratio against the allowed error fraction with the boolean modifier, because the result of the comparison then expresses the consumed proportion.
- Multiply the recorded error ratio by the objective expressed as a scalar, because scaling by the objective normalizes the ratio to the budget.
