1. ### F.1 Maths

Thickness of each paper based on the measured value = 48 / 500 = 0.096 mm...error = 0.096 X 1 / 240 = 0.0004 Therefore, upper limit of the thickness of a piece of paper = 0.096 + 0.0004 = 0.0964 mm Lower limit of the thickness ...

2. ### Can anyone help me ?

Absolute error of the thickness of 500 pieces      = 48mm × 1/240 = 0.2mm The thickness of each piece      = (48±0,2mm) ÷ 500      = 0.096±0.0004mm ∴ The possible range of x is  0.0956～0.0964 (mm).
