Answer:
C. 2,150
Step-by-step explanation:
We know that out of 120 passengers, 86 were satisfied with the service.
To find the percentage amount of passengers who were satisfied, we can divide 86 by 120 and get 0.716 repeating (about 71.6%).
Then, we can multiply the total number of passengers, 3,000, by that number and get 2,150.
Answer:

Step-by-step explanation:

Roots = 2, 4
A.O.S = 3.
The zeroes are where the parabola will meet the x-axis. The axis of symmetry pretty much just splits your parabola equally in half.
A- 98+89+123=310 (boys)
A-102+105+117=324 (girls)
B-324-310=14 I found my answer by subtracting the girls from the boys and I got 14
C-They will need to hire 24 more teachers because if you add the students together you will get 644 then you divide it by 20 and you get 32 but since they already have 8 teachers you would just subtract 8 from 32 wich you get 24
