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
