Work: Calculate the value of equation ((-15%-10.5%)^2×0.1+(10%-10.5%)^2×0.6+(20%-10.5%)^2×0.3)^0.5 .
Question type: Mathematical calculation
Solution:
((-15%-10.5%)^2×0.1+(10%-10.5%)^2×0.6+(20%-10.5%)^2×0.3)^0.5
=((-0.255)^2×0.1+(10%-10.5%)^2×0.6+(20%-10.5%)^2×0.3)^0.5
=(-0.255^2×0.1+(-0.005)^2×0.6+(20%-10.5%)^2×0.3)^0.5
=(-0.255^2×0.1+(-0.005)^2×0.6+0.095^2×0.3)^0.5
=0.009225^0.5
=0.096046863561493
Answer:((-15%-10.5%)^2×0.1+(10%-10.5%)^2×0.6+(20%-10.5%)^2×0.3)^0.5=0.096046863561493
