  up

Step-by-step explanation:

A graphing calculator, spreadsheet, or web site can help you with this one, or you can simply plot some points on a graph.

___

Only the highest-degree terms matter for answering this question. Leaving the others out, the form is ...

  y = x^2

This tells you that y gets more positive for larger and larger values of x, regardless of their sign. Thus the graph of it is U-shaped, opening upward.

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
