Penjelasan dengan langkah-langkah:

Nomor a.

Uda bener 135 cm ya ^^

[tex] \\ [/tex]

Nomor b.

Rata-rata :

[tex] \rm \frac{(135 \times 8) + (140 \times 14) + (145 \times 10) + (150 \times 8) + (155 \times 2)}{8 + 14 + 10 + 8 + 2} [/tex]

[tex] \rm = \frac{1080 + 1960 + 1450 + 1200 + 310}{42} [/tex]

[tex] \rm = \frac{6.000}{42} [/tex]

[tex] \bf = 142.86 \: cm[/tex]

Answer 2

1) TINGGI BADAN TERENDAH ADALAH 135 CM

2) DATA :

=> 135(8) = 1.080

=> 140(14) = 1.960

=> 145(10) = 1.450

=> 150(8) = 1.200

=> 155(2) = 310

TOTAL DATA :

= 8 + 14 + 10 + 8 + 2

= 22 + 18 + 2

= 40 + 2

= 42

MEAN :

= DATA/TOTAL

= 1.080 + 1.960 + 1.450 + 1.200 + 310/42

= 3.040 + 2.650 + 310/42

= 5.690 + 310/42

= 6.000/42

= 142,86
