Select all the correct answers. Use the graphing tool to find the roots of the quadratic equation you derived from the original rational equation in part B: x2 − 5x − 6 = 0. To use graphing to solve the equation, set the equation equal to 0, and replace the 0 with y. So, input this equation: y = x2 − 5x – 6. Observe the graph, and select the root(s) of the equation.

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
