The correct answer is somewhere
No.
EXPLANATION:
To tackled this problem we should find an equivalent denominator.
We find that the lcm ( lowest common denominator ) is 20.
1 x 5 = 5
4 x 5 = 20
2 x 4 = 8
5 x 4 = 20.
so the answer is no.
It is not possible to select a single group from the primary school, since being a single group it could not in any way represent the entire primary school.
Choosing a group would provide the average height for that group, not the entire primary.
Assumptions can be made that the course of half of the primary would theoretically give us a more accurate representation, but the objective is to select a number of students from each course and there would be a representative sample of the entire primary.
Answer:
h(t) = 12-t+6t^2 is a quadratic equation.
