The vertex is the extreme point of a parabola and is located halfway between the ___ and directrix. A. Center
B. Focus
C. Transverse axis

focas

Step-by-step explanation:

We are asked that the vertex, which is the extreme point of a parabola lies between focus and which point or line segment.

Attached herewith, a picture of a standard parabola. We can easily see that the focus and the directrix lies on two opposite sides of the vertex and the vertex is in the middle of the focus and the directrix.

So, the vertex lies in the halfway of the focus and the directrix.

Thus, the answer is the directrix.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
