Answer:
1/4
Step-by-step explanation:
You would do 64 divided by 6. You would divide it by 6 because it’s himself AND 5 friends. This would get you to 60. So now each friend has ten. Their would be four left over. So now Nick had 14 cards for himself.
Answer:
Expected time is 15 hours for him to get to safety.
Step-by-step explanation:
We define X as the time that this miner would get to safety.
We define Y as the door he chooses initially.
P(Y= 1) = P(Y=2)=P(Y=3) = 1/3
We have E[X|Y=1] = 3
E[X|Y] = 5 hours + E[X}
E[X|Y] = 7 hours + E[X]
Then we have
E[X] = 1/3(3 + 5 + E[X] + 7 + E[X])
We cross multiply
3*E[X] = (15 + 2E[x])
3E[X] - 2E[X] = 15
E[X] = 15
So the time it would take to get him to safety is 15 hours
No it's smaller. 12.56 is much less than 125.6.
Answer:
380d + 530t > 21,000
Step-by-step explanation:
Each DVD costs $380, we can represent that as:
380d
Each TV costs $530, we can represent that as:
530t
We add these together to find the total profit:
380d + 530t
The manager predicts that whatever the total profit is, will be more than $21,000. So, we represent that as this:
380d + 530t > 21,000
And that is the final answer.
