Mean = (14 + 16 + 7 + 9 + 11 + 13 + 8 + 10) ÷ 8 = 11

Variance = 
[ (14-11)²+(16-11)²+(7-11)²+(9-11)²+(11-11)²+(13-11)²+(8-11)²+(10-11)² ]/7 = 9.71

Answer: 9.71

A rectangular
igor_vitrenko [27]
A = length x width

15,000 = (w + 30) x w
15,000 = w^{2} + 30w
0 = w^{2} + 30w - 15,000

Use quadratic formula to find that  w= -15 + or - 5\sqrt{609}. Because distance cannot be negative, the width is -15 + 5\sqrt{609}meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
