The mean temperature for the first 7 days in january was 7 °c.

the temperature on the 8th day was 1 °c.

what is the mean temperature for the first 8 days in january?

6.25

Step-by-step explanation:

Mean temperature for first 7 days is

Sum of temperatures for each day ÷ number of days

7 = sum of temperatures for each day/7

Let x =Sum of temperatures for 7 days=x/7

x=49

For 8 days, total sum of temperatures is x +1 = 49+1 = 50

Mean temperature for first 8 days is

Sum of temperatures for each day ÷ number of days

= 50/8= 6.25
