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
