The answer is C and here are the steps
Answer:
the expected value of this raffle if you buy 1 ticket = -0.65
Step-by-step explanation:
Given that :
Five thousand tickets are sold at $1 each for a charity raffle
Tickets are to be drawn at random and monetary prizes awarded as follows: 1 prize of $500, 3 prizes of $300, 5 prizes of $50, and 20 prizes of $5.
Thus; the amount and the corresponding probability can be computed as:
Amount Probability
$500 -$1 = $499 1/5000
$300 -$1 = $299 3/5000
$50 - $1 = $49 5/5000
$5 - $1 = $4 20/5000
-$1 1- 29/5000 = 4971/5000
The expected value of the raffle if 1 ticket is being bought is as follows:





Thus; the expected value of this raffle if you buy 1 ticket = -0.65

Step-by-step explanation:
Answer:
A. How much Anna weights in kilograms is what is asked (Btw is it her or his?)
B. The values given is 54000 (most likely in grams )
C. The operation that is going to be used is 1000 since kilograms is 1000 grams
D. The solution is 54 kilograms
E. To get 54 kilograms to grams we can just multiply by 1000 again which will result into 54000 thus the answer is correct
Step-by-step explanation:
A:
The question is asked when there is a "what" or a problem statement
B:
The only value or digits given is 54000
C:
in the Metric Scale Kilograms is 1000 times larger in value than grams thus 1000
D:
Divide 54000 with 1000 which is 54
E:
Um.... just multiply 1000 ._. (That's the only way I can check it)
Hope this helps!
