Let the number be n.  Then 2(n-10) = 6n + 14.

Multiplying out the left side, 2n - 20 = 6n + 14.  Thus, -34=4n, and n = -17/2.

A class consists of 12 boys and 12 girls. The teacher picks five students to present their work to the rest of the class
Varvara68 [4.7K]

Answer:

0.01863, yes preference

Step-by-step explanation:

given that a class consists of 12 boys and 12 girls. The teacher picks five students to present their work to the rest of the class  and says that the five students are being selected at random

Here selecting any 5 students from the group of total 24 students is combination because order does not matter.

Total no of ways of selecting any 5 from total 24 = 24C5\\=42504

No of ways of selecting only 5 girls = No of ways of selecting random 5 girls from total 12 girls

= 12C5\\=792

a) the probability be that all five students

selected are girls=\frac{792}{42504} \\=0.01863

b) Since the probability for selecting all girls is very small and near to 0, it is unusual to select all girls if done at random.  Hence the teacher had a preference for girls.
