Oh ok. So I think that x is 83. Because I did this 630-100-121-106-112-108=83. And then I did 630/6 and got 105 and thats the mean.
1. $.0999 = $.1
2. $2.0192 = $2.02
3. $21.5953 = $21.60
4. $35.6667 = $35.67
5. $1.3999 = $1.40
6. $25.3333 = $25.33
So in order to compare, the measurements have to same units. So lets convert everything to feet.
George 2 yds = 6 ft Kelsey 68 inches = 5 ft 8"
Mariah 5 feet Brian 5 ft 10 "
George measured the tallest at 6'
Hope this helped.
