Indirect Variation . Thaum ob qhov hloov pauv hloov hauv thim rov qab proportion nws yog hu ua indirect variation . Hauv indirect variation ib variable yog lub sij hawm tas mus li thim rov qab ntawm lwm yam. Qhov no txhais tau tias hais tias cov variables hloov nyob rau hauv ib tug tib ratio tab sis inversely. General equation rau ib inverse variation yog y = K1x.
Ib yam li ntawd, kev hloov pauv ncaj qha thiab tsis ncaj yog dab tsi?
Hauv ncaj qha variation , raws li ib tug lej nce, yog li tus lwm. Qhov no kuj hu ua ncaj qha proportions: lawv yog tib yam. Ib qho piv txwv ntawm qhov no yog kev sib raug zoo ntawm hnub nyoog thiab qhov siab. Hauv inverse variation , nws yog qhov sib txawv: raws li ib tus lej nce, lwm qhov txo qis.
Kuj Paub, qhov kev hloov pauv ncaj qha thiab piv txwv yog dab tsi? Rau piv txwv ,yog y txawv ncaj qha li x, thiab y = 6 thaum x = 2, qhov tsis tu ncua ntawm kev hloov pauv yog k = = 3. Yog li, qhov sib npaug piav txog qhov no ncaj qha variation y = 3x. Yog li, muab ob lub ntsiab lus (x1, tus y1) thiab (x2, tus y2) uas txaus siab qhov sib npaug, = k thiab = k. Yog li ntawd, = rau ob lub ntsiab lus uas txaus siab rau qhov sib npaug.
Ib yam li ntawd, nws yog nug, dab tsi txawv indirectly txhais hauv lej?
Hais lus nruj me ntsis, ob yam khoom lossis qhov sib txawv " sib txawv indirect " txhais tau tias tias cov khoom ntawm ob yam khoom yog qhov tas mus li. Piv txwv li, x thiab y sib txawv indirectly txhais tau tias x* y yog tas li. Hais tias "ib qho txawv txav mus raws li qhov sib txawv mus" tsis tiav.
Kev sib raug zoo tsis ncaj yog dab tsi?
Ib indirect kev sib raug zoo yog a kev sib raug zoo ntawm ob qhov sib txawv uas cuam tshuam rau ib leeg. Piv txwv li, Variable A cuam tshuam rau Variable B, uas cuam tshuam rau Variable C. Variables A thiab C muaj qhov sib txawv. indirect kev sib raug zoo , i.e., los ntawm Variable B. Ob qhov sib txawv hauv ib qho indirect kev sib raug zoo feem ntau txav mus rau sab nraud.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Variation txhais li cas hauv psychology?
Qhov zoo ntawm kev hloov pauv lossis hloov pauv ntawm tus cwj pwm lossis kev xav. 2. qhov degree uas cov tswv cuab ntawm ib pab pawg lossis cov pej xeem sib txawv ntawm ib leeg, raws li ntsuas los ntawm kev txheeb cais xws li qhov ntau, tus qauv sib txawv, thiab qhov sib txawv
Yuav ua li cas indirect calorimetry ua?
Indirect calorimetry ntsuas kev siv hluav taws xob los ntawm kev kwv yees tus nqi oxidation ntawm lub zog macronutrients, rog, carbohydrate, thiab protein, los ntawm cov pa pauv ntawm pa oxygen thiab carbon dioxide thiab los ntawm kev tso tawm hauv cov zis ntawm cov khoom tsis tiav oxidized nitrogenous compounds
Vim li cas indirect calorimetry yog tus qauv kub?
Indirect calorimetry (IC) yog suav tias yog tus qauv kub los txiav txim siab kev siv hluav taws xob, los ntawm kev ntsuas pulmonary gas exchanges. Nws yog cov txheej txheem uas tsis muaj kev cuam tshuam uas tso cai rau cov kws kho mob tuaj yeem kho tus kheej daim ntawv xaj khoom noj khoom haus rau cov kev xav tau ntawm metabolic thiab txhawb nqa kev kho mob zoo dua
Yuav ua li cas yog indirect calorimetry?
Indirect calorimetry (IC) muab ib qho kev ntsuas siab tshaj plaws, raug, thiab tsis muaj kev ntsuas ntawm EE hauv ib tus neeg. Ob peb xyoos dhau los, cov txheej txheem no tau siv rau cov xwm txheej xws li mob hnyav thiab khoom noj khoom haus parenteral
