Step-by-step explanation:
So, we will take one of the numbers = x
And the other is 12 more than 3 times it, so = 3x + 12
So they said if we add them, we will get 4
So x + (3x + 12) = 4
4x + 12 = 4
4x = 4 - 12
4x = - 8
x = - 8 ÷4
x = - 2
So one of the numbers x = - 2
The other is 3x + 12
So x = - 2
3x +12 = 3(-2) + 12
= 6
So the 2 numbers = 6 and - 2
Lets check!
6 + (-2) = 4
So it's right!

Step-by-step explanation:
Answer:
45/8, or 5.625.
Step-by-step explanation:
(a) No preference is given to any one student?
<span>A simple combination of four selections out of 14: </span>
<span>
14! / (10! 4!) = 14*13*12*11 / (4*3*2*1) </span>
<span>
= 7*13*11 = 1,001 </span>
<span>(b) One particular student must be awarded an assistantship? </span>
<span>That leaves 3 selections out of 13 for the other positions: </span>
<span>
13! / (10! 3!) = 13*12*11 / (3*2*1) </span>
<span>
= 13*2*11 = 286 </span>
<span>(c) The group of applicants includes eight men and six women and it is stipulated that at least one woman must be awarded an assistantship? </span>
<span>We have the original 1,001 possibilities from part (a), minus all of those that awarded all the positions to men: </span>
<span>
1,001 - 8! / (4! 4!) = 1,001 - 8*7*6*5 / (4*3*2*1) </span>
<span>
= 1,001 - 70 = 931
