Sagot :

Answer:

1m 54cm

Step-by-step explanation:

10 students at 1m 40cm

15 students at 1m 58cm

13 students at 1m 60cm

Keep in mind that ratio between cm to m is 1cm/0.01m.

So let find the average by converting cm to m first for the 38 students.

10 students:  1m + (40cm)(0.01m/1cm) => 1.4 m

15 students:   1m  + 58cm(0.01m/1cm)  => 1.58 m

13 students:  1m 60cm(0.01m/1cm)  => 1.60 m

so the average is weighted:

(10*1.4 +15*1.58 + 13(1.6))/38

Therefore the average model height is 1.54 m or 1m 54cm
