The mean temperature for first 8 days in January is: 4.5 °C

Step-by-step explanation:

Given

Mean for 7 days = 5 Celsius degrees

So using the mean's formula

[tex]Mean = \frac{Sum}{Days}\\5 = \frac{Sum}{7}\\Sum = 7*5\\Sum = 35[/tex]

So the sum of temperatures for 7 days was 35

Now the temperature of 8th day will be added to sum and number of days will also be increased to 8

So,

[tex]Mean = \frac{Sum}{Days}\\Mean = \frac{35+1}{8}\\Mean = \frac{36}{8}\\=4.5[/tex]

So,

The mean temperature for first 8 days in January is: 4.5 °C
