Step-by-step explanation:
That question is accompanied by these answer choices:
<span>A. The scale is accurate but not precise.
B. The scale is precise but not accurate.
C. The scale is neither precise nor accurate.
D. The scale is both accurate and precise.
Then you need to distinguish between accuracy and precision.
Accuracy refers to the closeness of the measure to the real value, while precision, in this case, refers to the level of significant figures that the sacle report.
The fact that the scale reports the number with 4 significant figures means that it is very precise, but the fact that the result is not so close to the real value as the number of significan figures pretend to be, means that the scale is not accurate.
So, the answer is that the scale is precise but not accurate (the option B).

Answer:
Rate
Step-by-step explanation:
Rate is basically also a ratio. but it is the comparing of two different quantities with different units.
As ratio is comparing of same or identical quantities thus it has no units. But on the other hand as rate is the comparison of different quantities, thus it has units.
for example:
When i compare two quantities, 1st is a distance quantity and 2nd is a time quantity i.e.
20 meters : 15 seconds
thus the lowest form of this relationship will be:
4 meters : 3 seconds
when i write it in Decimal form it becomes :
Ans : 1.33 meters/second (Distance per unit time)
As this ratio have remaining units thus it is referred to as "RATE".
