Answer:
3g^2 - 2g + 12
Step-by-step explanation:
3g^2 - 7g + 5g + 12
-7g + 5g = -2g
Answer:
0.3333 = 33.33%
Step-by-step explanation:
We have 2 vacancies that will be filled from among 10 people, so the number of combinations we have is a combination of 10 choose 2, which is 10*9/2 = 45 possibilities.
Among these possibilities, the cases where the 2 vacancies are occupied by men is:
We have 6 men for 2 vacancies, so is a combination of 6 choose 2, which is 6*5/2 = 15 cases.
From the 45 cases we have, 15 are cases that no woman was selected, so the probability that no woman is selected is 15/45 = 1/3 = 0.3333 = 33.33%
The axis of symmetry would be (5, -27). To find the axis you can use two equations but for this question I used -b/2a. In the equation, the a is 1 and the b is -10. So, you would substitute it in and get 10/2 which would give you x=5. Then, you would substitute it into the equation. Like this —> y=(5)^2-10(5)-2. You would end up with y=25-50-2. This would give you a y of -27 leaving you with the answer (5,-27).
I believe The answer is C
