Answers
Answer:
Given that
the rainfall(in mm) in a city on 7 days of a certain week recorded as follows
Day Mon Tue Wed Thus Fri Sat Sun
Rainfall(in mm) 0.0 12.2 2.1 0.0 20.5 5.3 1.0
We range=Highest Rain fall−lowest rainfall
=20.5−0.0
Range of the rainfall=20.5mm
We know mean=No. of dayssum of rainfall in a city all days
=70+12.2+2.1+0+20.5+5.3+1
=741.1
Mean rainfall=5.87mm
from the above the data the rainfall less than mean rainfall
Day Mon Wed Thus Sat Sun
Rainfall(in mm) 0 2.1 0 5.3 1
Hence,
No. of days was rainfall less than the mean rainfall is 5 days
hope it helps
Answer:
1) 20.0mm
2) 5.9mm
3) 5 days
Step-by-step explanation:
1) range= maximum number–minimum number
= 20.0–0.0
= 0.0
2) mean= sum of rainfall of seven days
total number days
= 0.0+12.2+2.1+0.0+20.5+5.5+1.0
7
= 41.5
7
= 5.9mm
3) On Monday, Wednesday, Thursday, Saturday, Sunday were the days on which the rainfall less than the mean rainfall.
