Ten thousand raffle tickets are sold. One first prize of $1400, 3 second prizes of $800 each and 9 third prizes of $400 each will be awarded, with all winners selected randomly. If you purchase one ticket for $2, what are your expected net winnings?

answer:

1. 0.04

2. 0.15

step-by-step explanation:

i just finished that assignment for properties of probability distributions.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .

answer: given the scale 3,5 mm to 1 foot: so you know this and you need convert this 150mm to get the right answer.
