Question

consider the following thermometer, and use it to answer the question. calibration = (difference between 2 marked values) / (no of spaces between marked values) what value would you put in the numerator of this calibration? the numerator is the difference between two labeled values. options: 20, 5, 1, 10

Explanation:

Step1: Identify labeled values

The thermometer has labeled values (e.g., 20 and 30, or 10 and 20, etc.). Let's take two adjacent labeled values, say 20 and 30? Wait, no, looking at the marks: 10, 20, 30. Wait, the difference between two labeled values: let's check the marks. The labeled values (marked) are, for example, 20 and 30? Wait, no, the scale has 10, 20, 30. Wait, the difference between 30 and 20? Wait, no, maybe 30 - 20? Wait, no, let's see the spaces. Wait, the numerator is the difference between two labeled values. Let's take two labeled values, say 30 and 20? Wait, no, 30 - 20 = 10? Wait, no, 20 - 10 = 10? Wait, the options include 10. Wait, let's check the thermometer: the labeled values (marked) are, for example, 20 and 30? No, the marks are 10, 20, 30. So the difference between 30 and 20 is 10? Wait, 30 - 20 = 10. Or 20 - 10 = 10. So the numerator is the difference between two labeled values, which is 10 (e.g., 30 - 20 = 10, or 20 - 10 = 10).

Step2: Confirm the difference

The two labeled values (marked) on the thermometer: let's say we take 30 and 20. The difference is 30 - 20 = 10. Or 20 - 10 = 10. So the numerator is 10.

Answer:

10
