The diagonals of quadrilateral EFGH intersect at D (-1, 4). EFGH has vertices at E (2,7) and F (-3, 5). What must be the coordinates of G and H to ensure that EFGH is a parallelogram??

The diagonals of quadrilateral EFGH intersect at D(-1,4). Two vertices of EFGH are E(2,7) and F(-3,5). What must be the coordinates of G and H to ensure that EFGH is a parallelogram? Answer by Edwin ... We could finish by doing the same with the other diagonal. But we can also just realize that going

Step-by-step explanation:

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
