Answer» Answer: The average temperature will be 160° C Step-by-step EXPLANATION: ACCORDING to the given information, we can write that: at Monday the temperature was 220 C at Tuesday , the temperature was 200 C at Wednesday, the temperature was 180 C at Thursday, the temperature was 160 C at FRIDAY, the temperature was 140 C at SATURDAY, the temperature was 120 C at Sunday, the temperature was 100 C Now, simply do the average, of the above: (220 + 200 + 180 + 160 + 140 + 120 + 100)/7 = 1120/7 = 160 Therefore, the average temperature of the week is: 160 °C I hope it helps. Welcome in advance ;) |
