Twelve education students, in groups of four, are taking part in a student-teacher program. Mark cannot be in the first group be
Rina8888 [55]
This is a combination problem.

Given:
12 students
3 groups consisting of 4 students.
Mark can't be in the first group.

The combination formula that I used is: n! / r!(n-r)!
where: n = number of choices ; r = number of people to be chosen.

This is the formula I used because the order is not important and repetition is not allowed. 

Since Mark can't be considered in the first group, the value of n would be 11 instead of 12. value of r is 4.

numerator: n! = 11! = 39,916,800
denominator: r!(n-r)! = 4!(11-4)! = 4!*7! = 120,960

Combination = 39,916,800 / 120,960 = 330

There are 330 ways that the instructor can choose 4 students for the first group

Y=-2/3x+2 how to graph
Nikolay [14]

Step-by-step explanation:

Starting from y-intercept of [0, 2], you can either move two blocks <em>north</em><em> </em>over 3 blocks <em>west</em><em> </em>or two blocks <em>south</em><em> </em>over three blocks <em>east</em><em>.</em><em> </em>Either way, you will still get this line because this is a negative <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>].
