Answer:
So EASY
Step-by-step explanation:
The actual height of Karen = 142 cm
The measured height of Karen = 147 cm
We have to determine the approximate percent error of Karen's measurement.
The difference in the heights = 147 cm - 142 cm = 5 cm
So, Error percentage =
=
= 3.52
= 3.5 (approximately)
So, the approximate percent error of Karen's measurement = 3.5%
