[1/1 Formula]
Work: Calculate the value of equation sqrt(0.2*(0.5-0.18)^2+0.3*(0.25-0.18)^2+0.3*(0.15-0.18)^2+0.2*((-0.2)-0.18)^2) .
Question type: Mathematical calculation
Solution:
sqrt(0.2*(0.5-0.18)^2+0.3*(0.25-0.18)^2+0.3*(0.15-0.18)^2+0.2*((-0.2)-0.18)^2)
=sqrt(0.2*0.32^2+0.3*(0.25-0.18)^2+0.3*(0.15-0.18)^2+0.2*((-0.2)-0.18)^2)
=sqrt(0.2*0.32^2+0.3*0.07^2+0.3*(0.15-0.18)^2+0.2*((-0.2)-0.18)^2)
=sqrt(0.2*0.32^2+0.3*0.07^2+0.3*(-0.03)^2+0.2*((-0.2)-0.18)^2)
=sqrt(0.2*0.32^2+0.3*0.07^2+0.3*(-0.03)^2+0.2*((-0.2)-0.18)^2)
=sqrt(0.2*0.32^2+0.3*0.07^2+0.3*(-0.03)^2+0.2*(-0.38)^2)
=sqrt0.0511
=0.226053
Answer:sqrt(0.2*(0.5-0.18)^2+0.3*(0.25-0.18)^2+0.3*(0.15-0.18)^2+0.2*((-0.2)-0.18)^2)=0.226053
