There are the heights in meters of six members of swimming club
1.40,1.45,1.55,1.65,1.65,1.80


A-the median height
The range of a set of data is the sum between the highest and lowest values in the set, divided by+2
.
median=%281.40%2B1.80%29%2F2=1.6
B-the range
The range of a set of data is the difference between the highest and lowest values in the set.
range=1.80-1.40=0.4
C-One more person joins the club. The range is now 0.45+m and the median is 1.55 m. Find the height of the seventh person.
%281.40%2B1.45%2B1.55%2B1.65%2B1.65%2B1.80+%2Bx%29%2F7=++1.55+
x+=+1.35 m=>the height of the seventh person
