Answer:

$ 1.2

Step-by-step explanation:

The first thing is to define the expected value of the ticket that would be the sum of the value for all event probabilities.

That is, if you buy 1 ticket, for each participant the probabilities are:

1. 1/1000 to get a $ 1,200 item

2. 999/1000 to get nothing ($ 0).

That is to say:

(1/1000) * $ 1200 + (999/1000) * $ 0 = (1/1000) * $ 1200 = $ 1.2

Therefore, the expected value is $ 1.2, this means that in reality each participant pays $ 0.8 more than the ticket is worth

5. Graph the given system of linear inequalities on the coordinate plane below. (2 points)sy &lt;-3x - 4&lt; 21-15NA11 2 3 4 5 6
xxTIMURxx [149]

ANSWERS

(5) Graph:

(6) Solutions: (-1, -5) and (-2, -7)

Not solutions: (1, 1) and (-4, -3)

EXPLANATION

(5) To graph this system, first, we have to graph each of the inequalities. Both are linear, so we have to graph each line with a dashed line - this is because they are "less than" the line, so the line is not included, and shade the area below each of them.

The first inequality is y < -3x-4,

The second inequality is y < 2x - 1,

The graph of the system is the area shared by both graphs,

(6) Any point that is inside the shaded area is a solution of the system. For example, points (-1, -5) and (-2,-7) are solutions to the system.

On the other hand, any point outside that area, or on the dashed lines is not a solution. For example, points (1, 1) and (-4, -3) are not solutions
