20.解:(1)由题可知分数在[50,60)有2人,所以4010×0.0(1分)a=0.1-0.005-0.02-0.015-0.01=0.05(2分)(2)由频率分布直方图可知各组的频率分别为0.050.2,0.5,0.15,0.1,所以平均数=55×0.05+65×0.2+75×0.5+850.15+95×0.1=75.5(4分)设中位数为m,则(m-70)x0.05=0.5-(0.05+0.2),得m=75(6分)(3)由折线图中所给的数据计算,可得x=2+3+4+5+6=4,5=52+64+60+8+84=6因为∑(x-1)(y-5)=80,(x4-x)(y-y)所以b=1804+1+0+1+48所以a=68-8×4=36所以y=8x+36(10分)当x=1时,y=44,即估计该班第一次模拟考试的平均分为44分(12分)
