Lub npoo ntawm qhov yuam kev tuaj yeem suav ua ob txoj hauv kev:

Margin ntawm qhov yuam kev = Tus nqi tseem ceeb x Standarddeviation.
Margin ntawm qhov yuam kev = Tus nqi tseem ceeb x Standard yuam kev ntawm qhov txheeb cais.

Hauv qhov no, yuav ua li cas koj pom cov npoo ntawm qhov yuam kev rau ob qhov sib npaug?

Nov yog cov kauj ruam rau kev xam cov npoo ntawm qhov yuam kev fora piv txwv:

Nrhiav tus qauv loj, n, thiab tus qauv piv txwv.
Muab cov qauv piv txwv los ntawm.
Faib qhov tshwm sim los ntawm n.
Siv lub hauv paus square ntawm tus nqi xam.
Muab cov txiaj ntsig los ntawm qhov tsim nyog z *-tus nqi rau qib kev ntseeg siab xav tau.

Tsis tas li ntawd, Moe sawv cev rau dab tsi hauv kev txheeb cais? margin ntawm yuam kev

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub mis rau tus qauv yuam kev?

Txij li cov pejxeem txheem sib txawv yog seldomknown, lub txheem yuam kev ntawm qhov txhais tau tias feem ntau yog kwv yees tus qauv txheem sib txawv muab faib los ntawm lub hauv paus square ntawm tus qauv loj (piv txwv li kev ywj pheej ntawm cov nqi hauv cov qauv). n yog qhov loj (tus naj npawb ntawm kev soj ntsuam) ntawm cov qauv.

Dab tsi yog qhov sib txawv ntawm qhov yuam kev rau 95 kev ntseeg siab ib ntus?

Cov kws tshawb fawb feem ntau teem nws ntawm 90%, 95 % lossis 99%. kev ntseeg siab qib nrog kev ntseeg siab , uas yog ib tug synonym rau margin kev ua yuam kev .)

Yuav ua li cas koj pom cov hauv paus kev xav uas siv Descartes txoj cai ntawm cov paib?

Descartes txoj cai ntawm cov paib hais tias tus naj npawb ntawm cov hauv paus hniav zoo sib npaug rau kev hloov pauv ntawm f(x), lossis tsawg dua li ntawm tus lej sib npaug (yog li koj yuav rho tawm 2 mus txog thaum koj tau txais 1 lossis 0). Yog li ntawd, yav dhau los f(x) tej zaum yuav muaj 2 lossis 0 cov hauv paus zoo. Cov hauv paus hniav tsis zoo

Koj pom qhov siab ntawm lub thawv li cas thaum muab qhov chaw saum npoo?

Nrhiav Yam Txog Lub Thawv A lub thawv feem ntau yog tus yam ntxwv ntawm nws qhov siab, thiab nws qhov dav, W, thiab nws qhov ntev L. Qhov dav, qhov siab, thiab qhov ntev ntawm lub thawv tuaj yeem sib txawv. Qhov ntim, lossis qhov chaw nyob hauv lub thawv yog h × W × L. Qhov chaw sab nraud ntawm lub thawv yog 2 (h × W) + 2 (h × L) + 2 (W × L)

Koj pom qhov kev ntxub ntxaug thiab qhov xwm txheej ntawm cov hauv paus hniav li cas?

Qhov kev ntxub ntxaug (EMBFQ) Qhov no yog qhov qhia nyob rau hauv lub hauv paus square nyob rau hauv lub quadratic formula. Tus neeg ntxub ntxaug txiav txim qhov xwm txheej ntawm cov hauv paus hniav ntawm ib qho kev sib npaug plaub npaug. Lo lus ' xwm' yog hais txog cov naj npawb ntawm cov hauv paus hniav tuaj yeem yog - uas yog tiag tiag, rational, irrational lossis kev xav

Yuav ua li cas koj pom qhov sib npaug ntawm qhov nqus ntawm qhov nqus?

X = [Fe(SCN)2+] thiab yuav tsum tau txiav txim los ntawm tus qauv nkhaus. Tom qab ntawd koj tuaj yeem xam qhov sib npaug tas li, Keq, siv qhov sib npaug sib npaug. Tus qauv nkhaus yog ib zajlus ntawm Absorbance piv [Fe(SCN)2+] (Daim duab 8.1). Nws tuaj yeem siv los muab peb cov concentration ntawm cov tshuaj thaum muab cov absorbance
