Ua ib qho Histogram siv lub rooj faib khoom zaus
- Ntawm qhov ntsug axis, qhov chaw zaus . Sau lub axis no " Ntau zaus ".
- Ntawm kab rov tav axis, tso tus nqi qis ntawm txhua lub sijhawm.
- Kos ib qho bar txuas los ntawm tus nqi qis ntawm txhua lub sijhawm mus rau tus nqi qis ntawm lub sijhawm tom ntej.
Hauv qhov no, dab tsi yog qhov kev faib tawm zaus?
Hauv kev txheeb cais, a Kev faib tawm zaus yog ib daim ntawv, rooj los yog daim duab uas qhia cov zaus ntawm ntau yam tshwm sim hauv ib qho qauv. Txhua qhov nkag hauv lub rooj muaj cov zaus los yog suav ntawm qhov tshwm sim ntawm qhov tseem ceeb nyob rau hauv ib pab pawg neeg lossis lub sijhawm.
Tsis tas li ntawd, tus qauv ntawm zaus yog dab tsi? Cov qauv rau zaus yog: f ( zaus ) = 1 / T (lub sijhawm). f = c / λ = yoj ceev c (m / s) / wavelength λ (m). Cov qauv rau lub sij hawm yog: T (lub sij hawm) = 1 / f ( zaus ). λ = c / f = nthwv dej ceev c (m / s) / zaus f (Hz).
Tsis tas li ntawd, 3 hom kev faib tawm zaus yog dab tsi?
Hom Kev faib tawm zaus
- Pawg zaus faib.
- Ungrouped zaus faib.
- Kev faib tawm ntau zaus.
- txheeb ze zaus faib.
- Kwv tij txheeb ze sib faib zaus.
Koj pom qhov txhais tau li cas ntawm kev faib tawm zaus?
Yog tias peb muab txhua qhov nruab nrab ntawm nws zaus , thiab tom qab ntawd muab faib los ntawm tag nrho cov naj npawb ntawm qhov tseem ceeb hauv Kev faib tawm zaus , peb muaj kwv yees li ntawm txhais tau tias.

Yuav ua li cas koj xam qhov zaus ntawm zaus thiab feem pua?
Ua li no, faib cov zaus los ntawm tag nrho cov txiaj ntsig thiab muab faib los ntawm 100. Hauv qhov no, qhov zaus ntawm thawj kab yog 1 thiab tag nrho cov txiaj ntsig yog 10. Qhov feem pua yog tom qab ntawd yog 10.0. Cov kab kawg yog qhov feem pua Cumulative
Yuav ua li cas koj pom cov chav kawm ciam teb nyob rau hauv ib tug zaus faib lub rooj?
Cov ciam teb qis dua ntawm txhua chav kawm yog suav los ntawm kev rho tawm ib nrab ntawm qhov sib txawv ntawm tus nqi 12 = 0.5 1 2 = 0.5 ntawm chav kawm qis. Ntawm qhov tod tes, tus ciam teb sab saud ntawm txhua chav kawm yog suav los ntawm kev ntxiv ib nrab ntawm qhov sib txawv ntawm tus nqi 12 = 0.5 1 2 = 0.5 rau chav kawm sab saud. Simplify cov ciam teb qis thiab sab sauv kab
Yuav ua li cas koj nrhiav tau tus txheeb ze zaus nyob rau hauv ib txwm faib?
Faib cov suav (qhov zaus) los ntawm tag nrho tus lej. Piv txwv li, 1/40 = . 025 3/40 = . 075 ib
Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
Yuav ua li cas koj qhia yog hais tias ib tug piecewise graph yog ib tug muaj nuj nqi?
Yuav Qhia Li Cas Yog Piecewise Function yog Nruam lossis Tsis Txuas Ntxiv. Txhawm rau qhia yog tias daim duab sib txuas tsis tu ncua lossis tsis txuas ntxiv, koj tuaj yeem saib cov ntsiab lus ciam teb thiab pom tias y point yog tib yam ntawm lawv txhua tus.(Yog tias y's txawv, yuav muaj "dhia" hauv daim duab !)
