Answer:
False
Step-by-step explanation:
girls : boys : total
5 : 6 :11
Multiply each term by 2
10: 12 :22
Ratio of girls to boys
10:12
Divide by 2
5:6
The ratio of girls to boys is still 5:6 but the total students is 22
Matrix :
1 4 4
5 2 2
1 5 5
=> Determinant =
1 * (2*5 - 2*5) - 4 * (5*5 - 1*2) + 4 * ( 5*5 - 2*1)
= 1*(10 - 10) - 4*(25 - 2) + 4*(25 -2) = 1*0 + 4* 23 + 4*(25 - 2) = 0 - 4*23 + 4*23 = 0
