Sorry la.. terlebih dahulu aku nak cakap yang aku ni akan post banyak2 soalan yang aku tak paham pasal add math ni.. Maklum la aku ni jarang buat latihan add math. pasal aku ni suka mengadap komputer je..Nasib baik ada forum ni..

OK ni soalan aku pasal statistik.. Ni aku amik dalam buku aku dah cuba buat tapi tak dapat.

1. Nombor 4, 8, x, 15, 17, 21 telah disusun mengikut tertib menaik. Jika min nombor itu adalah sama dengan mediannya, tentukan nilai x.

----------------------End Question------------------------------

jawapan kat dalam buku ialah x= 10. Tapi macam mana jalan kerja dia?

Ha..baru saya dah dapat jawapan dia. Jawapan ni abang

saya kasi. Hari ni hari terakhir dia kat rumah sebab dia

nak balik U. Sebab tu la takde orang lain nak aja saya

add math cuti-cuti ni.. Harap2 lain kali anda semua dapat bantu saya..

Ni jawapan yang dia kasi..

[4+8+x+15+17+21]
[6]
 = Median

[4+8+x+15+17+21]
[6]
 =
[x+15]
[2]

Lepas tu selesaikan dengan cara darab silang.

[65+x]
[6]
 =
[x+15]
[2]
 ' Sampai sini je yang saya tak tau

rupa rupanya kena darab silang baru boleh dapat persamaan x

2(65+x) = 6(x+15)

130 +2x =6x+90

130-90 =6x-2x

40 = 4x

x=
[40]
[4]

x = 10

Kalau nak bincang soalan ni pun boleh jugak..
