A raffle has a grand prize of a Caribbean cruise valued at $14500 with a second prize of a Las Vegas getaway valued at $1500. If each ticket costs $3 and 8000 tickets are sold, what are the expected winnings for a ticket buyer? Express to at least three decimal place accuracy in dollar form (as opposed to cents).

Expected winning  = -$0.9988

Step-by-step explanation:

given data

cruise valued = $14500

getaway valued = $1500

ticket costs = $3

tickets sold =  8000

solution

we get here expected winnings for a ticket buyer so first we get

P (winning $14500) =

P(winning $1500) =  

P(loosing $3) = 1 - 2 ×    =  

so here Expected winning is

Expected winning  = ( $14500 - 3 ) ×  + ( 1500 - 3 ) × - ( 3 ) ×

Expected winning  = 1.8121 + 0.1871 - 2.998

Expected winning  = -$0.9988

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
