Scale a shows weights rounded to four decimal places while scale b shows weights rounded to thre decimal places which of the following bes describes the realtionship between scale a and b
a. scale b is more accurate then scale a
b. scale b has greater degree of precision then scale a
c. scale has a greater degree of precision then scale b
d. scale a is more accurate than scale b

D.scale a is more accurate than scale b

Step-by-step explanation:

Given is :

Scale a shows weights rounded to four decimal places.

Scale b shows weights rounded to three decimal places.

We can define accuracy as the difference between the measurement and the part's actual value.

But precision is defined as the variation we get, when we measure the same part repeatedly with the same device.

Here, its not given that the scales were measured many times and the results were numerous. So, we can go with option D. Scale a is more accurate than scale b. As it shows up to 4 decimal places.
