Work: Calculate the value of equation (3%-10.9%)^2*20%+(11%-10.9%)^2*50%+(16%-10.9%)^2*30% .
Question type: Mathematical calculation
Solution:
(3%-10.9%)^2*20%+(11%-10.9%)^2*50%+(16%-10.9%)^2*30%
=-0.079^2*20%+(11%-10.9%)^2*50%+(16%-10.9%)^2*30%
=-0.079^2*20%+0.001^2*50%+(16%-10.9%)^2*30%
=-0.079^2*20%+0.001^2*50%+0.051^2*30%
=-0.079^2*0.2+0.001^2*50%+0.051^2*30%
=-0.079^2*0.2+0.001^2*0.5+0.051^2*30%
=-0.079^2*0.2+0.001^2*0.5+0.051^2*0.3
=0.006241*0.2+0.001^2*0.5+0.051^2*0.3
=0.006241*0.2+0.000001*0.5+0.051^2*0.3
=0.006241*0.2+0.000001*0.5+0.002601*0.3
=0.001248+0.000001*0.5+0.002601*0.3
=0.001248+0+0.002601*0.3
=0.001248+0+0.00078
=0.001248+0.00078
=0.002028
Answer:(3%-10.9%)^2*20%+(11%-10.9%)^2*50%+(16%-10.9%)^2*30%=0.002028
