jangan lupa beserta penjelasanya ya kak,soalnya aku masi blm paham sama materinya
2. ¼n = ¼.80 = 20 Fi = 13
tbi = 49,5 p = 10
Fk = 9
Q₁ = tbi + ( ¼n - Fk / Fi ) p
= 49,5 + ( 20 - 9 / 13 ) 10
= 49,5 + ( 11/13 ) 10
= 49,5 + (110/13)
= 49,5 + 8,46
= 57,96
½n = ½.80 = 40 Fi = 20
tbi = 59,5 p = 10
Fk = 22
Q₂ = tbi + ( ½n - Fk / Fi ) p
= 59,5 + ( 40 - 22 / 20 ) 10
= 59,5 + ( 18/2 )
= 59,5 + 9
= 68,5
¾n = ¾.80 = 60 Fi = 14
tbi = 79,5 p = 10
Fk = 59
Q₃ = tbi + ( ¾n - Fk / Fi ) p
= 79,5 + ( 60 - 59 / 14 ) 10
= 79,5 + ( 1/7 ) 5
= 79,5 + (5/7)
= 79,5 + 0,714
= 80,214
