[1/1 Formula]
    Work: Calculate the value of equation sqrt(20%*(10%-17.5%)^2+30%*(15%-17.5%)^2+30*(20%-17.5%)^2+20%*(25%-17.5%)^2) .
    Question type: Mathematical calculation
    Solution:
          sqrt(20%*(10%-17.5%)^2+30%*(15%-17.5%)^2+30*(20%-17.5%)^2+20%*(25%-17.5%)^2)
        =sqrt(20%*(-0.075)^2+30%*(15%-17.5%)^2+30*(20%-17.5%)^2+20%*(25%-17.5%)^2)
        =sqrt(20%*(-0.075)^2+30%*(-0.025)^2+30*(20%-17.5%)^2+20%*(25%-17.5%)^2)
        =sqrt(20%*(-0.075)^2+30%*(-0.025)^2+30*0.025^2+20%*(25%-17.5%)^2)
        =sqrt(20%*(-0.075)^2+30%*(-0.025)^2+30*0.025^2+20%*0.075^2)
        =sqrt0.021188
        =0.145561

    Answer:sqrt(20%*(10%-17.5%)^2+30%*(15%-17.5%)^2+30*(20%-17.5%)^2+20%*(25%-17.5%)^2)=0.145561
