这五个的做法是一样的,以第一个为例,即0.08±10%×0.08
正负也就是指上下百分之10,上就是加上0.08的10%,下就是减去0.08的10%.
以此类推.能说的在具体点么？5种都要0.08±0.08×10%=[0.08-0.08×10%,0.08+0.08×10%]=[0.072,0.088]0.08±0.08×20%=[0.08-0.08×20%,0.08+0.08×20%]=[0.064,0.096]0.08±0.08×30%=[0.08-0.08×30%,0.08+0.08×30%]=[0.056,0.104]0.08±0.08×40%=[0.08-0.08×40%,0.08+0.08×40%]=[0.048,0.112]0.08±0.08×50%=[0.08-0.08×50%,0.08+0.08×50%]=[0.04,0.12]
