Olona vavanyo lufutshane lwe-IQ
UNjingalwazi Shane Frederick weMassachusetts Institute of Technology udale olona vavanyo lufutshane lwe-IQ olunemibuzo emithathu kuphela.
Ngokwengxelo yephephandaba isipili I-Bhritane, ukuba olu vavanyo lwasungulwa ngo-2005 ukumisela ubuchule bokuqonda, kwaye ngoku sele ipapashiwe kwi-Intanethi.
Imibuzo ifakiwe kuvavanyo
1- Irakethi kunye nebhola yentenetya zixabisa i- $ 1.10 kunye. Kwaye irakethi ibiza kakhulu kunebhola ngedola enye.
Yimalini ibhola iyodwa?
2- Oomatshini abahlanu kumzi-mveliso welaphu bavelisa iziqwenga ezintlanu kwimizuzu emihlanu.
Kuthatha imizuzu emingaphi ukuvelisa oomatshini abali-100?
3- Zikhula echibini leenyibiba zamanzi. Apho yonke imihla inani labo liphindeka kabini, kwaye kuyaziwa ukuba ezi nyibiba zingagubungela umphezulu wechibi ngaphakathi kweentsuku ezingama-48.
Zingaphi iintsuku iinyibiba ezifuna ukugubungela isiqingatha sobuso bedike?
Apho unjingalwazi wenza uvavanyo apho phantse abantu abangamawaka amathathu abavela kumacandelo ngamanqanaba ngamanqanaba emfundo, kwaye i-17% yabo ikwazile ukunika impendulo echanekileyo kule mibuzo. Unjingalwazi uxela ukuba uvavanyo ekuboneni kuqala lubonakala lula, kwaye kulula ukuluqonda emva kokucaciswa, kodwa kwimpendulo echanekileyo impendulo efika kuqala engqondweni kufuneka ishiywe.
iimpendulo eziqhelekileyo
Le mibuzo ziisenti ezili-10, imizuzu eli-100 kunye neentsuku ezingama-24 ngokwahlukeneyo. Kodwa ezi mpendulo azichanekanga. kuba
iimpendulo ezichanekileyo
Ngokwenyani ziisenti ezi-5, imizuzu emi-47, kunye neentsuku ezingama-XNUMX.
Ingcaciso yeempendulo ngolu hlobo lulandelayo
Ukuba ixabiso le-bat kunye nebhola ngokudibeneyo yi-1.10, kwaye ixabiso lerakhi lingaphezulu kwexabiso lebhola ngedola enye, kwaye sicinga ukuba ixabiso lebhola ngu "x", ke ixabiso bat kunye nebhola kunye ngu "x + (x + 1)".
Oko kukuthi, x + (x + 1) = 1.10
Oku kuthetha ukuba 2x + 1 = 1.10
Oko kukuthi, 2x = 1.10-1
2x = 0.10
x = 0.05
Oko kukuthi, ixabiso lebhola "x" lilingana neesenti ezintlanu.
Ukuba oomatshini aba-5 kwilitye lokusila bavelisa iziqwenga ezi-5 kwimizuzu emi-5, emva koko umatshini ngamnye uthatha imizuzu emi-5 ukuvelisa isiqwenga esinye. Kwaye ukuba besinoomatshini abali-100 abasebenza kunye, bebeya kuvelisa iziqwenga ezili-100 kwimizuzu emi-5.
Ukuba inani leenyibiba liyaphindeka, oko kukuthi, usuku ngalunye luphinda-phinda usuku olungaphambili, kwaye usuku ngalunye oludlulileyo sisiqingatha sosuku olukhoyo, oko kuthetha ukuba iinyibiba ziya kugubungela isiqingatha sobuso beli chibi ngomhla wama-47.
