Isivivinyo esifushane se-IQ
USolwazi Shane Frederick weMassachusetts Institute of Technology udale isivivinyo esifishane se-IQ esiqukethe imibuzo emithathu kuphela.
Ngokuthola kwaleli phephandaba Mirror AbaseBrithani, ukuthi lolu vivinyo lwasungulwa ngo-2005 ukuthola amakhono okuqonda, futhi manje selushicilelwe kwi-Intanethi.
Imibuzo ifakiwe esivivinyweni
1- Irakhethi nebhola lethenisi kufanele u- $ 1.10 ndawonye. Futhi irakhethi libiza kakhulu kunebhola ngedola elilodwa.
Malini ibhola lilodwa?
2- Imishini emihlanu efektri yendwangu ikhiqiza izingcezu ezinhlanu ngemizuzu emihlanu.
Kuthatha imizuzu emingaki ukukhiqiza izingcezu eziyi-100?
3- Zikhula echibini leminduze yamanzi. Lapho nsuku zonke inani lazo liphindeka kabili, futhi kuyaziwa ukuthi le minduze ingamboza ubuso bechibi zingakapheli izinsuku ezingama-48.
Kuthatha izinsuku ezingaki ukumboza ingxenye yobuso bechibi?
Lapho uprofesa enza khona isivivinyo lapho cishe abantu abayizinkulungwane ezintathu abavela emikhakheni ehlukene namazinga ehlukene emfundo babambe iqhaza, kwathi i-17% yabo yakwazi ukunikeza impendulo eyiyo kule mibuzo. Uprofesa uveza ukuthi isivivinyo ekuqaleni sibonakala silula, futhi kulula ukusiqonda ngemuva kokucaciswa, kepha ukuthola impendulo eyiyo impendulo eza engqondweni kuqala kufanele ishiywe.
izimpendulo ezivamile
Le mibuzo ngamasenti ayi-10, imizuzu eyi-100, nezinsuku ezingama-24, ngokulandelana. Kepha lezi zimpendulo azilungile. ngoba
izimpendulo ezifanele
Empeleni kungamasenti ama-5, imizuzu emi-47, nezinsuku ezingama-XNUMX.
Incazelo yezimpendulo kanje
Uma intengo yelulwane nebhola ndawonye ingu-1.10, futhi intengo yerakhi ingaphezu kwentengo yebhola ngedola elilodwa, futhi sicabanga ukuthi inani lebhola lingu “x”, bese inani lentengo bat kanye nebhola ndawonye "x + (x + 1)".
Lokho ukuthi, x + (x + 1) = 1.10
Lokhu kusho ukuthi 2x + 1 = 1.10
Okungukuthi, 2x = 1.10-1
2x = 0.10
x = 0.05
Okusho ukuthi, intengo yebhola "x" ilingana namasenti ama-5.
Uma imishini emi-5 esigayweni sendwangu ikhiqiza izingcezu ezi-5 ngemizuzu emi-5, khona-ke umshini ngamunye uthatha imizuzu emihlanu ukukhiqiza ucezu olulodwa. Futhi uma besinemishini eyi-5 esebenza ngokubambisana, bebezokhiqiza izingcezu eziyi-100 ngemizuzu emi-100 futhi.
Uma inani leminduze liphindaphindeka, okungukuthi, usuku ngalunye luphinda kabili usuku lwangaphambilini, futhi usuku ngalunye lwangaphambilini luyingxenye yosuku lwamanje, okusho ukuthi iminduze izomboza ingxenye yobuso bechibi ngosuku lwama-47.
