Ungasebenzisa i NGE -itafile ukufumana iseti epheleleyo yezinto ezingaphantsi kwamathuba kuluhlu olubanzi lwe nge -ixabiso. Sebenzisa i NGE- table yokufumana amathuba e isampula yamanani ngomgangatho oqhelekileyo ( NGE- ukuhanjiswa, yenza oku kulandelayo:

  1. Yiya kumqolo omele amanani kunye namanani okuqala emva kwenqaku lokugqibela (inani leshumi) lakho nge -xabiso.



  2. Yiya kwikholam emele isuntswana lesibini emva kwenqaku lokugqibela (inani lamakhulu lekhulu) lakho nge -xabiso.

  3. Hlangana nomqolo kunye nekholamu ukusuka kwiNyathelo 1 kunye nelesi-2.

    Esi siphumo simele iphe ( NGE < nge ), Amathuba okuba ukwahluka okungahleliwe NGE ingaphantsi kwexabiso nge (ekwabizwa ngokuba yipesenti nge Iimpawu ezingaphantsi kokunikiweyo nge Ixabiso).

    i-vyvanse yinto elawulwayo

Umzekelo, masithi ufuna ukufumana iphe ( NGE <2.13). Using the NGE -Ithebhile engezantsi, fumana umqolo we-2.1 kunye nekholamu ye-0.03. Hlangana nomqolo kunye nekholamu ukufumana amathuba: 0.9834. Ke ngoko iphe ( NGE <2.13) = 0.9834.

Ukuqaphela ukuba indawo iyonke phantsi kwayo nayiphi na ijika eliqhelekileyo (kubandakanya igophe eliqhelekileyo eliqhelekileyo) ngu-1, kuyalandela oko iphe ( NGE <2.13) + iphe ( NGE > 2.13) = 1. Ke ngoko, iphe ( NGE > 2.13) = 1 -> iphe ( NGE <2.13) which equals 1 – 0.9834 which equals 0.0166.

I-adderall iya kubangela ukuba unciphise umzimba

Masithi ufuna ukukhangela iphe ( NGE <–2.13). You find the row for –2.1 and the column for 0.03. Intersect the row and column and you find 0.0166; that means iphe ( NGE <–2.13)=0.0166. Observe that this happens to equal iphe ( NGE Isizathu soku yile 'kuba ulwabiwo oluqhelekileyo luyalingana. Ke umsila wegophe elingezantsi -2.13 elimele iphe ( NGE <–2.13) looks exactly like the tail above 2.13 representing iphe ( NGE > +2.13).
