Question

The temperatures, in °C , at midnight on 10 consecutive days were 4, 1, 0, –2, –1, –3, 1, –2, 3, –1. (a) Find the difference between the highest and the lowest temperature

Answer 1

7 degrees C

Explanation:

To solve this question, we can start by ordering the temperatures from least to greatest:

4, 1, 0, -2, -1, -3, 1, -2, 3, -1 --> -3, -2, -2, -1, -1, 0, 1, 1, 3, 4

the lowest temperature would be -3 in this list, and the highest temperature in this list would be 4. We can find the difference in temperature using subtraction:

4-(-3) = 4+3=7

The difference is 7 degrees C.
