76% of students were not supportive.

you find the answer by gathering the total number of students not supportive over the total number of students. in this case it would be \frac{190}{250} . then, you simplify it so that its a number over 100, so it would be \frac{76}{100} . Then, you just convert that to a percentage, 76%

Equations Of Parabolas (Conics) Unscramble
abruzzese [7]

The match is shown in the picture for the function of a parabola and the graph of a parabola.

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

As we know the standard form of the parabola is:

y = a(x - h)² + k

If a > 0 (parabola opens upwards)

If a < 0 (parabola opens downwards)

or

x = a(y - h)² + k

If a > 0 (parabola opens right side)

If a < 0 (parabola opens left side)

Here (h, k) is the vertex of the parabola and a is the leading term.

Thus, the match is shown in the picture for the function of a parabola and the graph of a parabola.
