Answer 1

Penjelasan dengan langkah-langkah:

mean =

[tex] \tt \frac{(4,8 \times 10) + (6,0 \times 15) + (8,0 \times 35) + (8,5 \times 40)}{10 + 15 + 35 + 40} = [/tex]

[tex] \tt \frac{48 + 90 + 280 + 340}{100} = [/tex]

[tex] \tt \frac{758}{100} = \purple{ \boxed{ \tt 7,58}}[/tex]

Answer 2

DATA KESELURUHAN :

=> 4,8(10) => 48

=> 6,0(15) => 90

=> 8,0(35) => 280

=> 8,5(40) => 340

TOTAL DATA KESELURUHAN :

= (10 + 15 + 35 + 40)

= (25 + 75)

= 100

MAKA :

MEAN = BD/TD

= (48 + 90 + 280 + 340)/100

= (138 + 620)/100

= 758/100

= 7,58
