It’s easier to see and solve if you draw the picture
To find LD you need to subtract CD to CL
CD - CL = LD
14.2 - 5.3 = 8.9
=> LD = 8.9
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
Answer:
d=12
Step-by-step explanation:
15-d/4+2=1/2
15-d/6=1/2
2(15-d)=6
30-2d=6
30-6=2d
24=2d
d=12
<span>Expand 3x (2x-1)
3x outside must </span>multiply both terms inside
the brackets:
= 6x^2 - 3x
Hope it helps
