jika mean = 47,875 maka berapa nilai P? Nilai = 38.43.48.53.58 Frekuensi = 6.8.P.9.5

[tex]47.875 = 48 + \frac{ - 1}{28 + x} \times 5 \\ 47.875 - 48 = \frac{ - 5}{28 + x} \\ - 0.125 = \frac{ - 5}{28 + x} \\ - 3.5 + - 0.125x = - 5 \\ - 0.125x = - 5 + 3.5 \\ - 0.125x = - 1.5 \\ x = \frac{ - 1.5}{ - 0.125} \\ x = 12[/tex]
