Which graph represents the following system of inequalities? y > 2x - 5 y <-3x
1 answer:
Answer:
The graph i the attached figure
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area above the dotted line
The slope of the dotted line is positive
The x- intercept of the dotted line is the point (2.5,0)
The y- intercept of the dotted line is the point (0,-5)
-----> inequality B
The solution of the inequality B is the shaded area below the dotted line
The slope of the dotted line is negative
The x- intercept of the dotted line is the point (0,0)
The y- intercept of the dotted line is the point (0,0)
The solution of the system of inequalities is the shaded area between the two dotted lines

Answer:
Step-by-step explanation:
If we assume that the boys and girls are equally likely, so the probability of having a girl is equal to probability of having a boy = .
Let B = Event of having a boy.
G= Event of having a girl.
Since both events are independent of each other . (Events that do not depends on each other.)
So irrespective of the four baby boy , the probability that the fifth child is a boy =
Therefore , the probability of a couple having a baby boy when their fifth child is born, given that the first four children were all boys=
