Daftar Isi
penerima ulangan matematika terdiri dr 40 orang siswa kelas XI A, 35 orang siswa kelas XI B, & 25 siswa kelas XI C. nilai rata-rata seluruh akseptor ialah 7.2, sedangkan nilai rata-rata kelas XI A & kelas XI B yaitu 7. nilai rata-rata kelas XI C yaitu
Rata rata campuran = X1×f1 + X2×f2 + X3×f3 f1+f2+f3
7,2 = 7×40 + 7×35 + X3×25
40+35+25
7,2 = 280 + 245 + 25×X3
100
720 = 280 + 245 + 25×X3
720 = 525 + 25×X3
720-525 = 25×X3
195 = 25×X3
195 = X3
25
7,8 = X3
X3 = rata rata XI C
x nya diganti sama simbol rata rata yaaa =)
hasil hitunganku segini, maaf jikalau berbeda pertimbangan =)
