Work: Calculate the value of equation √0.4*(2%-3.4%)^2+0.4*(3%-3.4%)^2+0.2*(5%-3.4%)^2 .
Question type: Mathematical calculation
Solution:
√0.4*(2%-3.4%)^2+0.4*(3%-3.4%)^2+0.2*(5%-3.4%)^2
=√0.4*(-0.014)^2+0.4*(3%-3.4%)^2+0.2*(5%-3.4%)^2
=√0.4*(-0.014)^2+0.4*(-0.004)^2+0.2*(5%-3.4%)^2
=√0.4*(-0.014)^2+0.4*(-0.004)^2+0.2*0.016^2
=0.632456*-0.014^2+0.4*-0.004^2+0.2*0.016^2
=0.632456*0.000196+0.4*(-0.004)^2+0.2*0.016^2
=0.632456*0.000196+0.4*0.000016+0.2*0.016^2
=0.632456*0.000196+0.4*0.000016+0.2*0.000256
=0.000124+0.4*0.000016+0.2*0.000256
=0.000124+0.000006+0.2*0.000256
=0.000124+0.000006+0.000051
=0.00013+0.000051
=0.000181
Answer:√0.4*(2%-3.4%)^2+0.4*(3%-3.4%)^2+0.2*(5%-3.4%)^2=0.000181
