tolong bantu jwb pr mtk aku 2-5

2a) terendah = 44
tertinggi = 99
2b) interval. jumlah
44 - 50. 2
51 - 57. 7
58 - 64. 5
65 - 71. 4
72 - 78. 6
79 - 85. 8
86 - 92. 6
93 - 99. 2

3) gmbr diagram batang

4) b) 12th = 130
14 th = 140
16 th = 160
c) 17 th

5) a) makan = 40% = 40/100 = 2/5 × 360° = 144°
pakaian = sewa rumah = 15% = 15/100 = 3/20 × 360° = 54°
listrik = 12,5% = 12,5 / 100 = 1/8 × 360° = 45°
disimpan = 10% = 10/100 = 1/10 × 360° = 36°
lain2 = 360° - 144° - 54° - 54° - 45° - 36° = 27°
tinggal gambar lingkaran terus bisa digambar batasannya, tinggal ngikutin jumlah sudutnya aja.
b) lain2 = 100% - 40% - 15% - 15% - 12,5% - 10% = 7,5 % × 18.000.000 = 1.350.000
