Question

if jocelyn estimates that a pice of wood is 5.5 cm long and it is acually 5.62 cm then what is the percent error and how do u get that answer ?

Answer 1

Percent error = (|measured − actual| / actual) × 100%.

Here: |5.50 − 5.62| = 0.12 cm, so percent error = (0.12 / 5.62) × 100% ≈ 2.135% ≈ 2.14% (≈ 2.1% if rounded to two sig figs).
