the system of inequity is
from the given graph it is noticed that we have two related lines. one is solid and another is dashed.
if a line passing through two points, then the equation of line is
the solid line passing through the points (0,4) and (4,0).
the related equation of solid line is .
similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).
the related equation of dashed line is
from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.
check the related equations by the point (0,1).
this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is
similarly, check the second related equation.
it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
percentage - 25%
probability - 0.25
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
probability will be 0.25
