Question

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

Efficiency = EoEi100
Efficiency = the fraction with numerator cap e o and denominator cap e i 100

Efficiency = EiEo
Efficiency = cap e i over cap e o

Efficiency = EiEo
100
Efficiency = cap e i over cap e o100

Efficiency = EoEi

The mathematical representation of a machine's efficiency is typically given by:

\[
\text{Efficiency} = \frac{E_o}{E_i} \times 100
\]

Where \( E_o \) represents the output energy or work done by the machine and \( E_i \) represents the input energy supplied to the machine.

From the options you provided, the correct representation is:

**Efficiency = \( \frac{E_o}{E_i} \times 100 \)**

Or, in your notation:

**Efficiency = cap e o over cap e i 100**
