Work: Calculate the value of equation (-2%-10.4%)^2*20%+(9%-10.4%)^2*50%+(21%-10.4%)^2*30% .
Question type: Mathematical calculation
Solution:
(-2%-10.4%)^2*20%+(9%-10.4%)^2*50%+(21%-10.4%)^2*30%
=-0.124^2*20%+(9%-10.4%)^2*50%+(21%-10.4%)^2*30%
=-0.124^2*20%+(-0.014)^2*50%+(21%-10.4%)^2*30%
=-0.124^2*20%+(-0.014)^2*50%+0.106^2*30%
=-0.124^2*0.2+-0.014^2*50%+0.106^2*30%
=-0.124^2*0.2+-0.014^2*0.5+0.106^2*30%
=-0.124^2*0.2+-0.014^2*0.5+0.106^2*0.3
=0.015376*0.2+(-0.014)^2*0.5+0.106^2*0.3
=0.015376*0.2+0.000196*0.5+0.106^2*0.3
=0.015376*0.2+0.000196*0.5+0.011236*0.3
=0.003075+0.000196*0.5+0.011236*0.3
=0.003075+0.000098+0.011236*0.3
=0.003075+0.000098+0.003371
=0.003173+0.003371
=0.006544
Answer:(-2%-10.4%)^2*20%+(9%-10.4%)^2*50%+(21%-10.4%)^2*30%=0.006544
