Final answer:
The difference between the average low temperature of 10°F and the actual low temperature of -2°F on a winter day is 12°F, corresponding to option B.
Step-by-step explanation:
The difference in the temperatures between the average low and the actual low can be calculated by subtracting the actual low temperature from the average low temperature. In this case, we subtract -2°F (the actual low) from 10°F (the average low), which gives us:
10°F - (-2°F) = 10°F + 2°F = 12°F
Therefore, the difference between the average low temperature and the actual low temperature on that winter day is 12°F, which corresponds to option B.
The difference in temperatures is the absolute value of the difference between the average low temperature and the actual low temperature. In this case, the average low temperature is 10°F and the actual low temperature is -2°F.
Subtracting -2°F from 10°F gives us 12°F. However, since the question asks for the difference, which is always positive, we take the absolute value of 12°F, which is 12°F.
So, the difference in temperatures is 12°F.
