Sagot :
add first the heights
1.08 m
+ 1.4 m
+ 1.26 m
+ 1.32 m
+ 1.48 m
-----------------
=6.54 m
divide the sum by the no. of values. the number is 5, since there are 5 heights needed to be averaged
6.54 m
-------------
5
=1.308 or 1.31 m is the average height
1.08 m
+ 1.4 m
+ 1.26 m
+ 1.32 m
+ 1.48 m
-----------------
=6.54 m
divide the sum by the no. of values. the number is 5, since there are 5 heights needed to be averaged
6.54 m
-------------
5
=1.308 or 1.31 m is the average height
First Method
Formula (In Phrase)
Add all the values, then the sum will be divided into how many values you have added overall.
Formula (Algebraic Expression)
(v + v) / nv
Wherein
v = value
nv = no. of values
1.08 (1st v.)
1.40 (2nd v.)
1.26 (3rd v.)
1.32 (4th v.)
+ 1.48 (5th v.)
6.54 ÷ 5 = 1.308
So, rounding off, the answer is 1.308 when rounded is 1.3
