Craig measured a length as 0.034 millimeters. what is the margin of error? 0.03 mm to 0.04 mm 0.033 mm to 0.034 mm 0.0345 mm to 0.0350 mm 0.0335 mm to 0.0345 mm

  0.0335 mm to 0.0345 mm

Step-by-step explanation:

The least significant digit of Craig's measurement is in the 0.001 mm place. The error in the measurement is presumed to fall within half that value either side of Craig's measurement. So, the actual value is expected to be in the range ...

  0.034 -0.0005 = 0.0335

to

  0.034 +0.0005 = 0.0345

The measurement is presumed to be in the range 0.0335 mm to 0.0345 mm.

the first one, all those points on the line just make a strait line.
