A thermometer measures temperature to the nearest 0.5°C which measurement shows an appropriate level of precision for the thermo

statuscvo [17]

Answer:

Step-by-step explanation:

To the nearest 0.5°C means basically 1 digit after the decimal point.

0.5 has 1 digit (5), after the decimal point. To the nearest 0.5 means that the answer should have 1 digit after the decimal point.

For example, if we were to round 14, to the nearest 0.5, we would need to write it as 14.0 (with 1 digit after decimal).

Now, looking at the answer choices, we eliminate A because it has 2 digits after decimal. We eliminate B and C because there is NO DIGIT after decimal. And we accept D, because it has 1 digit after decimal. Hence, this is correct to the nearest 0.5°C.

Answer is D
