Work: Calculate the value of equation (5%-8.6%)^2*20%+(8%-8.6%)^2*50%+(12%-8.6%)^2*30% .
Question type: Mathematical calculation
Solution:
(5%-8.6%)^2*20%+(8%-8.6%)^2*50%+(12%-8.6%)^2*30%
=-0.036^2*20%+(8%-8.6%)^2*50%+(12%-8.6%)^2*30%
=-0.036^2*20%+(-0.006)^2*50%+(12%-8.6%)^2*30%
=-0.036^2*20%+(-0.006)^2*50%+0.034^2*30%
=-0.036^2*0.2+-0.006^2*50%+0.034^2*30%
=-0.036^2*0.2+-0.006^2*0.5+0.034^2*30%
=-0.036^2*0.2+-0.006^2*0.5+0.034^2*0.3
=0.001296*0.2+(-0.006)^2*0.5+0.034^2*0.3
=0.001296*0.2+0.000036*0.5+0.034^2*0.3
=0.001296*0.2+0.000036*0.5+0.001156*0.3
=0.000259+0.000036*0.5+0.001156*0.3
=0.000259+0.000018+0.001156*0.3
=0.000259+0.000018+0.000347
=0.000277+0.000347
=0.000624
Answer:(5%-8.6%)^2*20%+(8%-8.6%)^2*50%+(12%-8.6%)^2*30%=0.000624
