The width of a photograph is 4 inches. tori measures its width using the two rulers, both of which measure in inches.
which statement is true about the accuracy and precision of the rulers?

a the measurement found using ruler 1 is more accurate and more precise.
b the measurement found using ruler 2 is more accurate and more precise.
c the measurement found using ruler 1 is more accurate but less precise.
d the measurement found using ruler 1 is more precise but less accurate.

B The measurement found using Ruler 2 is more accurate and more precise.

Step-by-step explanation:

We have to understand the concept here for accuracy and precision.

Accuracy is against some standard. So it is the measured value which is closely against a standard. Accuracy is less if the measured value is deviated from the standard.

Precision is about how closely individually measured values agree with each other. Precision doesn't concern with the standard value.

Now, third concept is significant numbers. It is up to how much decimal numbers an instrument can produce a result.

In ruler 2, you can see that there are more divisions for a whole inch. This means that the ruler 2 can measure more nearly to the standard value, as well as, for repeated measurements, it can give more precised figures due to the ability to read up to more decimal numbers after the decimal point.

you already gave the answer

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
