To solve for F in the equation D = 6 5 ​ ( F + G ) , you can isolate F by first multiplying both sides by 6, then dividing by 5, and finally subtracting G. The final expression for F is F = 5 6 D ​ − G . This allows you to express F in terms of D and G.

Jawaban:1. Rata-rata = 7,52. Median = 7Penjelasan dengan langkah-langkah:Nilai Jumlah Siswa 5 4 6 6 7 12 8 7 9 6 10 5 1. Rata-rata:-Kalikan setiap nilai dengan jumlah siswanya:5 × 4 = 206 × 6 = 367 × 12 = 848 × 7 = 569 × 6 = 5410 × 5 = 50Jumlah semua = 300Total siswa = 40Rumus: [tex] \frac{jumlah \: semua}{total \: siswa} \\ \\ = \frac{300}{40} = 7.5[/tex]2. Median-Urutkan semua data (nilai) dari yang terkecil sampai besar 5, 5, 5, 5, 6, 6, 6, 6, 6, 6, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 8, 8, 9, 9, 9, 9, 9, 9, 10, 10, 10, 10, 10-Ambil data yang ditengah. Karena jumlah data genap (40), median = nilai ke-20 dan ke-21.-Data ke-20 = 7-Data ke-21 = 7[tex]median= \frac{data \: ke20 + data \: ke21}{2} \\ \: \: \: \: = \frac{7 + 7}{2} = \frac{14}{2} = 7[/tex]
