Answer:
a, b, d
Step-by-step explanation:
For the inequality x ≥ -3 . . .
a(0, -2) . . . 0 ≥ -3, true
b(-3, 4) . . . -3 ≥ -3, true
c(-4, 2) . . . -4 ≥ -3, FALSE
d(5, -5) . . . 5 ≥ -3, true
Points a, b, d satisfy the inequality.
B
Let total number of students be x.
Ratio of boys to girls= 5:7
=5x:7x
According to question,
5x =95
Or x=95/5
x=19
Now,
Number of girls =7x
=7*19
=133
10
