The mean temperature for the first 7 days in January was 3 °C. The temperature on the 8th day was 5 °C. What is the mean tempera
andre [41]

Answer: 3.25°C

Step-by-step explanation:

From the question, we are given the information that the mean temperature for the first 7 days in January was 3 °C. This means that the total temperature for the first 7 days in January was:

= 3°C × 7

= 21°C

We are also told that the temperature on the 8th day was 5°C. To calculate the the mean temperature for the first 8 days in January, we add the total temperature for the 8 days and then divide by 8.

The total temperature for the 8 days will be: = 21°C + 5°C = 26°C.

The mean temperature for the first 8 days in January will now be:

= 26°C/8

= 3.25°C
