Heath Reeves · Answer 1

Absolute error = 2m

Step-by-step explanation:

Absolute Error = Measured Value - Actual Value

17m - 15m = 2m

Matthias Pacheco · Answer 2

2m and 11.8%

Step-by-step explanation:

Absolute error is defined mathematically as;

Error/original value

[Original value - estimated value]

[17-15 ] = 2m

The percentage error would be

[Original value - estimated value] / original value

[17-15 ] / 17 * 100%

0.1176 * 100% = 11.76%

11.8%[ to the nearest tenth]
