A digital scale reports a 10 kg weight as weighing 9.998 kg. Which of the following is true?

A.the scale is both accurate and precise.
B.the scale is accurate but not precise.
C.the scale is precise but not accurate.
D.the scale is neither precise nor accurate.

Respuesta :

A)

Accurate = close to the 'true' value, and 9.998 is close to 10. Imagine a scale that has the zero point wrong as says 8.998, it would not be accurate, but still precise (several digits known)

Precise = several digits known. I would say to know it until grams is quite a good precision (the 9.998 has 4 digits)
