Question

What is the mathematical representation of a machine’s efficiency? (1 point)
Responses

Efficiency=EoEi100
Efficiency equals Start Fraction upper E subscript o baseline over upper E subscript i baseline End Fraction 100

Efficiency=EiEo
Efficiency equals Start Fraction upper E subscript i baseline over upper E subscript o baseline End Fraction

Efficiency=EiEo100
Efficiency equals Start Fraction upper E subscript i baseline over upper E subscript o baseline End Fraction 100

Efficiency=EoEi100

Answer 1

Correct: Efficiency=EoEi100
