Question

If an instrument measures in units of 5, then any value between which two values would be measured as 35?

A) 27.5 and 32.5
B) 30 and 40
C) 32.5 and 37.5
D) 34.5 and 35.5

Answer 1

D) 34.5 and 35.5

Explanation:

The instrument isn't capable of distinguish differences that are less than 5. So, your instrument only "knows" the difference between 30, 35 and 40.

Both numbers 34.5 and 35.5 are close enough to 35, so that the instrument wouldn't say they are 30 or 40, and so it will always output 35.

Answer 2

D) 34.5 and 35.5.

Explanation:

If the value is between 34.5 and 35.5, then it will be measured as five, because the instruments only reads number base on units of 5, so, this interval only give one option to the instrument to read, and that's 5 because is in the middle, it's the average inside this interval.

On the other hand, other intervals have too wide ranges of values, which will allow the instrument to read multiple values as a result, not only 35.

Therefore, the correct answer is D.
