Question

thermometer
consider the following thermometer, and
use it to answer the question.
calibration = (difference between 2 marked values) / (# of spaces between marked values)
what value would you put in the
denominator for this calibration?
5
0.1
1
10

Explanation:

Step1: Identify marked values

Marked values (e.g., 20 and 30) have a difference, but we need the number of spaces between them. Looking at the thermometer, between 20 and 30 (or 10 and 20), count the spaces. From 20 to 30, how many intervals? Let's see: each major mark (10,20,30) has spaces. Between 20 and 30, the number of spaces (intervals) is 10? Wait, no, wait. Wait, the thermometer: let's check the scale. From 20 to 30, how many small lines? Wait, the options include 10. Wait, let's re-express. The formula's denominator is the number of spaces between marked values. Let's take two marked values, say 20 and 30. How many spaces (the number of divisions) between them? Looking at the thermometer, between 20 and 30, there are 10 spaces (since each space is 1 unit? Wait, no, wait. Wait, the marked values: 10,20,30. Between 10 and 20: how many spaces? Let's count the lines. From 20 to 30, the number of spaces (the number of intervals) is 10. So the denominator is the number of spaces between marked values, which is 10. Wait, let's confirm. The formula is calibration = (difference between 2 marked values) / (number of spaces between marked values). So if two marked values are 20 and 30, difference is 10. The number of spaces between them: looking at the thermometer, between 20 and 30, there are 10 spaces (since each space is 1, so 30 - 20 = 10, and number of spaces is 10). So the denominator is 10.

Step2: Confirm the number of spaces

Looking at the thermometer, between 20 and 30 (or 10 and 20), the number of spaces (the number of divisions) is 10. So the denominator is 10.

Answer:

10 (corresponding to the option D. 10, assuming the options are A.5, B.0.1, C.1, D.10) Wait, the options given are 5, 0.1, 1, 10. So the correct option is 10. So the answer is 10 (the option with 10).
