The "expected value of a ticket" is the probability of being drawn multiplied by the earnings associated to being drawn.
($1 is the price of the ticket which of course can be different).
So in this case probability is 1/2000 and the earnings would be valued $1000 (value of the plasma TV).
The expected value is 1/2000*1000=1000/2000=$0,5
This means you should not buy a $1 ticket to play except if this really brings you LOTS of amusement ;)
Answer:5
Step-by-step explanation:
If you look at the question in reverse you can backtrack your way through. Take 10 and instead of dividing, multiply it by 10, which is 60, add 6 instead of subtracting, which is 66, divide by 6 instead of multiplying, which is 11 and finally subtract 6 instead of adding, which is 5. Use five and try the question over to make sure you calculated correct.
X=2
To check it you plug in 2 for x. Which then gives you:
3+(2-14)=-15+6 which then gives you:
3+-12=-15+6 which the gives you:
-9=-9
$42.35. 36/.85= 42.3529412
Answer:
-0.5
Step-by-step explanation:
2n-3 >= 1-4n+7
2n-10>= 1-4n
2n-11>=4n
-11>=2n
-0.5>= n
