Chebyshev's theorem yog siv txhawm rau nrhiav qhov kev faib ua feem ntawm kev soj ntsuam koj xav kom pom nyob rau hauv ob qho kev sib txawv ntawm qhov nruab nrab. Chebyshev cov Interval yog hais txog cov ntu uas koj xav pom thaum siv lub theorem . Piv txwv li, koj lub sijhawm yuav yog los ntawm -2 mus rau 2 tus qauv sib txawv ntawm qhov nruab nrab.
Cov lus nug tseem yog, Chebyshev lub theorem yog dab tsi?
Chebyshev's Theorem yog qhov tseeb uas siv tau rau tag nrho cov ntaub ntawv teev tseg. Nws piav qhia txog qhov tsawg kawg nkaus ntawm kev ntsuas uas dag yuav tsum nyob rau hauv ib, ob, los yog ntau tshaj tus qauv sib txawv ntawm qhov txhais tau tias.
Tsis tas li ntawd, Chebyshev qhov tsis sib xws ntsuas li cas? Chebyshev qhov tsis sib xws (tseem hu ua Tchebysheff's kev tsis sib xws ) yog a ntsuas ntawm qhov kev ncua deb ntawm qhov nruab nrab ntawm ib qho random cov ntaub ntawv taw tes hauv ib txheej, qhia raws li qhov tshwm sim. Nws hais tias rau cov ntaub ntawv teeb tsa nrog qhov sib txawv tsis tu ncua, qhov tshwm sim ntawm cov ntaub ntawv taw qhia nyob hauv k tus qauv sib txawv ntawm qhov nruab nrab yog 1 / k2.
Ntawm no, Chebyshev qhov tsis sib xws siv rau dab tsi?
Chebyshev qhov tsis sib xws , kuj hu ua Chebyshev cov theorem, yog ib qho cuab yeej txheeb cais uas ntsuas kev tawg ntawm cov ntaub ntawv pej xeem. Nws tuaj yeem yog siv nrog ib qho kev faib cov ntaub ntawv, thiab tsuas yog nyob ntawm qhov nruab nrab thiab tus qauv sib txawv ntawm cov ntaub ntawv.
Yuav ua li cas yog lwm lub npe rau txoj cai empirical?
Lwm lub npe rau cov txoj cai empirical yog “68-95-99.7 txoj cai ”. Qhov no npe yog tsim nyog vim qhov no txoj cai muab kwv yees feem pua ntawm cov ntaub ntawv.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
