老师帮我看一下第二题

老师您能先看一下我这个吗，我这个提交作业快到了

老师您能先看一下我这个吗，我这个提交作业快到了

高低点法：b=(104-50)/(116-48)=0.79 a%2B0.79*48=50 a=50-0.79*48=12.08 总成本=12.08%2B0.79*135=118.73万元

老师回归分析法的ab和总成本您算出来是多少

48*50%2B53*54%2B55*56%2B68*64%2B90*85%2B116*104=32408 平均产量=(48%2B53%2B55%2B68%2B90%2B116)/6=71.67 50%2B54%2B56%2B64%2B85%2B104=413 48^2%2B53^2%2B55^2%2B68^2%2B90^2%2B116^2=34318 48%2B53%2B55%2B68%2B90%2B116=430 b=(32408-71.67*413)/(34318-71.67*430)=0.80 a=(50%2B54%2B56%2B64%2B85%2B104)/6%2B0.80*71.67=126.17 总成本=126.17%2B0.80*135=234.17万

好的，谢谢老师
