[1/1 Formula]
    Work: Calculate the value of equation (15%-11%)^2×0.3+(10%-11%)×0.6+(5%-11%)^2×0.1 .
    Question type: Mathematical calculation
    Solution:
          (15%-11%)^2×0.3+(10%-11%)×0.6+(5%-11%)^2×0.1
        =0.04^2×0.3+(10%-11%)×0.6+(5%-11%)^2×0.1
        =0.04^2×0.3+(-0.01)×0.6+(5%-11%)^2×0.1
        =0.04^2×0.3+(-0.01)×0.6+(-0.06)^2×0.1
        =0.0016×0.3+(-0.01)×0.6+(-0.06)^2×0.1
        =0.0016×0.3+(-0.01)×0.6+0.0036×0.1
        =0.00048+(-0.01)×0.6+0.0036×0.1
        =0.00048+(-0.006)+0.0036×0.1
        =0.00048+-0.006+0.00036
        =-0.00552+0.00036
        =-0.00516

    Answer:(15%-11%)^2×0.3+(10%-11%)×0.6+(5%-11%)^2×0.1=-0.00516
