Exact b,e inexact a,c,d,f
Work Step by Step
Exact Numbers have values that are known exactly, and inexact values have uncertainty to them, normally due to measurement. Measurement A is inexact, because it is obtained using a measurement, which will never be exact. Measurement B is exact because it is an integer obtained from a constant group. Measurement C is inexact because the temperature could change depending on location, and measurements are not exact. Measurement D is inexact because it is obtained through a measurement, which is inexact. Measurement E is exact because it is a conversion factor, which is always exact. Measurement F is inexact because averages are obtained through measurements, which are inexact.
