Answer:
25%
Step-by-step explanation:
2500*4 = 10000
10000/4 = 2500
its 1/4 of the students
25%
Its one of the two first ones, I can’t really figure it out but that’s a hint
The number of solutions of a quadratic equation
ax^2+bx+c=0
Depends on its discriminant
/Delta=b^2-4ac
If /Delta>0 there are two distinct solutions
If /Delta=0 there are two coincident solutions
If /Delta<0 there are no solutions.
We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:

We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:
b^2-4ac=9+28t>0\iff t>-\dfrac[9][28]
Graph B.
Because y< so shade underneath the line
And because it is less then not less than or equal to then the line is dashed.
