Answer 1

-8-2-4-1=-15................

Answer 2

Calculation of Temperature Change

To find the temperature at 11 o'clock, we need to calculate the cumulative change in temperature from 8 o'clock to 11 o'clock.

The given temperature changes are as follows: - From 8 o'clock to 9 o'clock: -2° - From 9 o'clock to 10 o'clock: +4° - From 10 o'clock to 11 o'clock: +1°

To calculate the cumulative change, we add up these temperature changes: - Cumulative change = (-2°) + (+4°) + (+1°) = 3°

Finding the Temperature at 11 o'clock

To find the temperature at 11 o'clock, we add the cumulative change to the temperature at 10 o'clock.

Given: - Temperature at 10 o'clock: -8°

Adding the cumulative change of 3° to the temperature at 10 o'clock, we get: - Temperature at 11 o'clock = -8° + 3° = -5°

Therefore, the temperature at 11 o'clock is -5°.
