OK.......
First you would divide 750 by 30
That is 25
Next you divide 225 by 25
That is 9
Thats how many boxes the manager needs to order = 9
H0P3 It H3LPS :)
im pretty sure it is 4.18x10^13
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
11y-36= 63° because of the angles theorem.
I'm guessing you mean a^2? if so then,
a^2+28a+27=
(a+1)(a+27)
