Divide 240 by 45 you would get 5 and 1/3, multiply 5 and one third by 60 and it would result in 320.
D. 320 would be the correct answer.
18*3 = 54
20*3 = 60
so the scale drawing would be 54cm x 60cm

Frequency = 5
<u>Adult</u>
Mean = 6.2 cm
Frequency = 3
The mean length of these 8 people's index finger is calculated as:
So, we have
Mean = (5.6 * 5 + 6.2 * 3)/(5 + 3)
Evaluate
Mean = 5.83
Hence, the mean length (rounded to 2 DP) of these 8 people's index finger is 5.83
