Answer:
percent error ≈ 29. 7 %
Step-by-step explanation:
percentage error = absolute error / exact value × 100
where
absolute error = |approximate value - exact value|
approximate value = 45
exact value = 64
absolute error = |45 - 64| = 19
percentage error = absolute error / exact value × 100
percentage error = 19/64 × 100
percentage error = 1900/64
percentage error = 29.6875 %
To the nearest tenth
percent error ≈ 29. 7 %
