12 = 4*3 = 2*2*3
8 = 4*2 =2*2*2
greatest common factor = 2*2 =4
they can have 4 teams: consisting of 3 boys and 2 girls
If each face is 80m² and there are 4 identical faces, the answer would be 4 x 80 = 320m² - C

Answer:
0.4494
Step-by-step explanation:
Given :
marks number of students
20-29 8
30-39 12
40-49 20
50-59 7
60-69 3
The range Coefficient is obtained thus :
Range Coefficient = (Xm - Xl) / (Xm + Xl)
Where ;
Xm = Mid value of highest class = (60+69)/2 = 64.5
Xl = Mid value of lowest class = (20+29)/2 = 24.5
Range Coefficient = (64.5 - 24.5) / (64.5 + 24.5)
Range Coefficient = 40 / 89 = 0.4494
