Answer:
-$0.67
Step-by-step explanation:
If you buy one ticket, the possible outcomes are:
100% chance of spending $1 (buying the ticket)
1 in 5,000 chance of winning $500
3 in 5,000 chance of winning $300
5 in 5,000 chance of winning $30
20 in 5,000 chance of winning $5.
The expected value of the raffle is determined by:
The expected value of this raffle if you buy 1 ticket is -$0.67.
We went from -12 degrees to 27 degrees.
27 - (-12) = 27 + 12 = 39
Answer:
This question is incomplete
Step-by-step explanation:
This question is incomplete. However, the dish (among the three dishes A, B and C) that has the highest temperature would make the food dish the warmest when placed on it.
The process of heat transfer that involves physical contact as described in this question is conduction. It involves the transfer of heat energy from a hot object to a less hot/cooler object. Using the question, the molecules in the top dish (which will have a high kinetic energy because of it's heat energy) will move and collide with the molecules in the food dish (which, prior to the collision, will have a low kinetic energy as a result of low thermal energy) to make it warm. This would cause the temperature in the top dish to reduce while simultaneously increasing the temperature of the food dish (as it is a form of heat transfer) thereby also increasing the kinetic energy of the molecules of the food dish. The temperature of food dish will not be more than the temperature of the top dish.
