Answer:
Step-by-step explanation:
(3x + 4)(x + 3)
3x^2 + 9x + 4x + 12
3x^2 + 13x + 12
A measurement of 0.6 grams means that the 'true' answer lies between
<span>0.55 and 0.65 </span>
In general, the uncertainty in a single measurement from a single instrument is half the least precise decimal given for the instrument.
The precision for this measurement is in the tenths place.
so we take 0.1 /2 = 0.05, and divide by the measurement
<span>0.05 / 0.6 = 0.08333 = 8.3 %</span>
