Referring to the above 5x=13
Then x=13/5=2.6
For y
2(2.6)+2y=0
Y= -5.2/2=-2.6
X=2.6
Y= -2.6
Option C
2100 different committees that can be formed from 5 teachers and 10 students
<em><u>Solution:</u></em>
A school committee consists of 2 teachers and 4 students
The number of different committees that can be formed from 5 teachers and 10 students is to be found
This is a combination problem
A combination is a selection of all or part of a set of objects, without regard to the order in which objects are selected
<em><u>The formula to calculate combinations is:</u></em>
where n represents the number of items, and r represents the number of items being chosen at a time
Here we have to choose 2 teacher from 5 teacher and 4 student from 10 student
Hence we get,
Number of committees =
To get the factorial of a number n the given formula is used,
Therefore,
Thus 2100 different committees that can be formed from 5 teachers and 10 students
