Answer 1

Verified answer

23) jumlah siswa
= 3 + 7 + 13 + 6 + 6 + 5
= 40 siswa
jumlah siswa yg mendapat nilai diatas 7
= 6 + 6 + 5
= 17
% siswa yg nilainya diatas 7
= 17/40 × 100%
= 42,5 %

24) jumlah ternak
= 10 + 6 + 4
= 20 ekor
bagian kerbau
= 4/20 × 360°
= 1/5 × 360°
= 72°

25) rata2 = { ( 5×60) + ( 10×70 ) + ( 20×80) + ( 10×90 ) + ( 5×100) } / ( 5 + 10 + 20 + 10 + 5 )
x = ( 300 + 700 + 1600 + 900 + 500 ) / 50
x = 4.000 / 50
x = 80
jadi rata2 = 80
