Answer:
35
Step-by-step explanation:
This is a combination problem therefore we need to use the combination formula using factorials, plug in the values for n and r which would be 7 since there are 7 individuals in the group and 3 because we are making outcomes of 3.
C(n,r)=C(7,3)
=7!(3!(7−3)!)
=7!3!×4!
= 35
Finally, we can see that the total number of possible outcomes is 35

23.95×12=287.4+135=422.4
39,500-422.4=39,077.6
Step-by-step explanation:
x = 2 , y = 7
ans, y = 11 - 2x and 4x - 3y = -13
→ 7 = 11 - 2(2) → 7 = 11 - 4 → 7 = 7
→ 4(2) - 3(7) = -13 → 8 - 21 = -13 → -13 = -13
x = 5 , y = 2
→ 2x + y = 12 and x = 9 - 2y
as, 2(5) + 2 = 12 → 10 + 2 = 12 → 12 = 12
x = 9 - 2y → 5 = 9 - 2(4) → 5 = 9 - 4 → 5 = 5
x = 3 , y = 5
ans. 2x + y = 11 , x - 2y = -7
2(3) + 5 = 11 → 6 + 5 = 11 → 11 = 11
3 - 2(5) = 7 → 3 - 10 = 7 → 7 = 7
x = 7 , y = 3
ans. x + 3y = 16 and 2x - y = 11
7 + 3(3) = 16 → 7 + 9 = 16 → 16 = 16
2(7) - 3 = 11 → 14 - 3 = 11 → 11 = 11
