Umthetho ochaziweyo wokujonga

Rekhoda iziphumo ezingama-28 zevili laseYurophu. Isiqalisi esisasazwayo sifuna inani eliphindiweyo phakathi kwemijikelo 26–28 kwaye izikhewuizixhoboIsikhewuEsinye sezikhewu ezingama-37 ezinamanani kwirotha. Kwakhona: slot, cup.Funda yonke → ezahlukeneyo zingabi ngaphezu kwama-21 kwirekhodi iphela. Olu hlalutyo lunciphisa ulungelelwanisoizixhoboIbhodi yokubhejaIgridi yokubheja eshicilelwe etafileni. Kwakhona: itafile, ilaphu.Funda yonke → lube zizikhewu ezahlukeneyo ezingama-21 ngqo kuba umthetho awuchazi imeko engaphantsi kwama-21. Xa kubonwe izikhewu ezahlukeneyo ezingama-21 ngqo, izikhewu ezili-16 kwezingama-37 zihlala zingaphumanga, ngoko beka itshiphuimaliItshiphuUphawu olumele isixa esimiselweyo, olubekwa kwibhodi yokubheja ukwenza ibheji. Kwakhona: check.Funda yonke → enye yenani elinye kwinye nganye kuloo manani ali-16 kumjikelo olandelayo. Ukujonga kuchonga ulungelelwaniso; akuqikeleli isikhewu esilandelayo.

Imeko ebalulekileyo engasonjululwanga

Izikhewu ezahlukeneyo ezingaphantsi kwama-21 zishiya amanani angaphezu kwali-16 engaphumanga. Umthetho awuthi ngawaphi amanani angaphumanga ekufuneka eshiywe, ngoko loo meko lukhetho olungachazwanga, hayi imvume yokukhetha ngokuthe cwaka naziphi na ezili-16. Olu hlalutyo ke luvavanya ulungelelwaniso olunye kuphela oluchazwe ngokupheleleyo: iibheji zenani elinye ezili-16 ngqo zetshiphu enye.

Itheyibhile yeentlawulo zamanani ali-16 amiselweyo

Zonke iitshiphu ezili-16 zisebenza kwibheji nganye. Impumelelo yenani elinye ibuyisa kangama-36 itshiphu yayo kubandakanya itshiphu ngokwayo, ngelixa ezinye iitshiphu ezili-15 zilahleka.

Umzekelo osetyenzisiweyo

Masithi irekhodi inezikhewu ezahlukeneyo ezingama-21 ngqo nokuphinda okusi-7, kunye nokuphinda okunye kwimijikelo 26–28. Isiphelelisi ke liqela elicacileyo lamanani ali-16. Ukuba umjikelo olandelayo ngomnye kwezo zili-16, imbuyekezo yawo yenani elinye yeyunithiimaliIyunithiIbheji esisiseko esetyenziswa yinkqubo okanye ngumdlali. Ukunyuswa kweebheji kuchazwa ngeeyunithi ukuze kusebenze kuyo nayiphi na itafile.Funda yonke → enye ngama-36 kwaye okwenyani emva kwazo zonke iitshiphu ezili-16 ngu-+20. Ukuba sisinye kwezinye izikhewu ezingama-21, akukho tshiphu ibuyisayo kwaye isiphumo ngu-−16. Irekhodi yangaphambili ayiwatshintshi amathuba angu-16/37 no-21/37.

Izikhewu ezahlukeneyo asiyomida eqinileyo

Emva kwemijikelo engama-37 ezimeleyo yevili laseYurophu, inani elilindelekileyo lezikhewu ezahlukeneyo ngama-23.5745. Lo mndilili asiyophahla: ithuba lokubona izikhewu ezahlukeneyo ezingaphezu kwama-24 ngama-31.2839%. Umndilili wokuhlalwa uchaza iisampuli ezininzi; awubeki buninzi kwirekhodi ethile okanye wenze imijikelo yamva ihlawulele ukuphinda kwangaphambili.

Umngcipheko nolindelo

Kulungelelwaniso olumiselweyo, okwenyani okulindelekileyo ngu-(16 × 20 − 21 × 16) / 37 = −16/37 iiyunithi kwibheji nganye. Leyo yilahleko eqhelekileyo yaseYurophu ye-2.70% esetyenziswa kwiiyunithi ezili-16 zemali ebhejiweyoimaliIsixa esipheleleyo esibhejiweyoIsixa esipheleleyo esibhejiweyo kwiseshoni okanye kwixesha elithile, kubalwa nemali ephumeleleyo ephinda ibhejwe. Kwakhona: handle, action.Funda yonke →. Ulungelelwaniso lungenza isiphumo se-+20 senzeke rhoqo ngaphezu kokubetha kwebheji enye yenani elinye, kodwa lukwabeka emngciphekweni iiyunithi ezili-16 nanini na kungawi namnye kumanani alo akhethiweyo. Ukukhetha amanani abandayo akutshintshi nokugquma nexabiso elilindelekileyoizibaloIxabiso elilindelekileyoIsiphumo esiphakathi kwibheji nganye ekuhambeni kwexesha elide. −1/37 yebheji kuyo yonke ibheji eqhelekileyo yaseYurophu.Funda yonke →.
