Work: Calculate the value of equation ((50%-21%)^2*0.3+(30%-21%)^2*0.2+(10%-21%)^2*0.3+(-15%-21%)^2*0.2)^(1/2) .
Question type: Mathematical calculation
Solution:
((50%-21%)^2*0.3+(30%-21%)^2*0.2+(10%-21%)^2*0.3+(-15%-21%)^2*0.2)^(1/2)
=(0.29^2*0.3+(30%-21%)^2*0.2+(10%-21%)^2*0.3+(-15%-21%)^2*0.2)^(1/2)
=(0.29^2*0.3+0.09^2*0.2+(10%-21%)^2*0.3+(-15%-21%)^2*0.2)^(1/2)
=(0.29^2*0.3+0.09^2*0.2+(-0.11)^2*0.3+(-15%-21%)^2*0.2)^(1/2)
=(0.29^2*0.3+0.09^2*0.2+(-0.11)^2*0.3+(-0.36)^2*0.2)^(1/2)
=0.0564^(1/2)
=0.0564^0.5
=0.237486841740758
Answer:((50%-21%)^2*0.3+(30%-21%)^2*0.2+(10%-21%)^2*0.3+(-15%-21%)^2*0.2)^(1/2)=0.237486841740758
