a player pays $15 to play a game in which a chip is randomly selected from a bag of chips. the bag contains 10 red chips, 4 blue chips, and 6 yellow chips. the player wins $5 if a red chip is selected, $10 if a blue chip is selected, and $20 if a yellow chip is selected. let the random variable x represent the amount won from the selection of the chip, and let the random variable w represent the total amount won, where w=x−15. what is the mean of w ?
The mean of w which represents the total amount won where w = x + 15 is;
w = -$4.5
We are given;
Winnings if a red chip is selected; x₁ = $5.
Now, there are 10 red chips in a bag of 20 chips.
Thus, the probability of this outcome is:
p₁ = 10/20
p₁ = 1/2
Winnings if a blue chip is selected; x₂ = $10
Now, there are 4 blue chips in a bag of 20 chips.
Thus, the probability of this outcome is:
p₂ = 4/20
p₂ = 1/5
Winnings if a yellow chip is selected; x₃ = $20
Now, there are 6 blue chips in a bag of 20 chips.
Thus, the probability of this outcome is:
p₃ = 6/20
p₃ = 3/10
Finally, the expected value is:
E(X) = 5(¹/₂) + 10(¹/₅) + 20(³/₁₀)
E(X) = $10.5
We are told that w = x - 15
where x is the amount won from selection of chip which is E(X) = $10.5
Thus;
w = 10.5 - 15
w = -$4.5

Earth's internal heat source concept map.
It should be noted that the internal heat source of the Earth provides the energy that the Earth needs.
The flow of the internal heat of the Earth is typically outward towards the surface of the Earth.
The sources of heat in the Earth include the heat gotten when the planet forms, frictional heating, and the heat that is gotten from the decay of the elements that are radioactive.

If you are working on the part of 5-15 minutes, time-stamping (every 30 seconds) should start at.
A timestamp is an indication (also called a marker) which tells us at what time / when the relevant text was spoken. They are represented in the format [HH:MM:SS]; where HH are hours, MM are minutes, and SS are seconds - from the beginning of the audio or video file.
There are different kinds of timestamps as below:
1. Periodic timestamps - Periodic timestamps appear at a consistent frequency. They can appear for every 15 seconds, 30 seconds, 1 minute, or 2 minutes.
2. Paragraph timestamps
3. Sentence timestamps
4. Speaker timestamps
Time stamping format used while transcribing audio files is:
[00:00:00]
where [hour:minute:second]
so 5th minute is [00:05:00]
If the 5 - 15 minute part of an audio has to be transcribed stamping should be started at [00:05:00]
If a client requests time stamping every 30 seconds the next timestamp would be [00:05:30]

A child riding a bicycle at 15 m/s accelerates at 3. 0 m/s/s for 4. 0 s. What is the child's speed at the end of this 4. 0 s interval?.
Answer:
The final speed of bicycle would be 27 m/s².
Step-by-step explanation:
Given :
[tex]\small\red\bull[/tex] Initial velocity (u) = 15 m/s[tex]\small\red\bull[/tex] Acceleration (a) = 3.0 m/s²[tex]\small\red\bull[/tex] Time = 4 secondsTo Find :

Which sentence from Mark Twain's essay "Advice to Youth" conveys Twain's opinion about why one’s youth is the right time to learn good values?
Being told I would be expected to talk here, I inquired what sort of talk I ought to make. They said it should be something suitable to youth--something didactic, instructive, or something in the nature of good advice. Very well. I have a few things in my mind which I have often longed to say for the instruction of the young; for it is in one’s tender early years that such things will best take root and be most enduring and most valuable. First, then. I will say to you my young friends--and I say it beseechingly, urgingly-- Always obey your parents, when they are present. This is the best policy in the long run, because if you don't, they will make you. Most parents think they know better than you do, and you can generally make more by humoring that superstition than you can by acting on your own better judgment.
Be respectful to your superiors, if you have any, also to strangers, and sometimes to others. If a person offend you, and you are in doubt as to whether it was intentional or not, do not resort to extreme measures; simply watch your chance and hit him with a brick. That will be sufficient. If you shall find that he had not intended any offense, come out frankly and confess yourself in the wrong when you struck him; acknowledge it like a man and say you didn't mean to. Yes, always avoid violence; in this age of charity and kindliness, the time has gone by for such things. Leave dynamite to the low and unrefined.
Answer:
I have a few things in my mind which I have often longed to say for the instruction of the young; for it is in one’s tender early years that such things will best take root and be most enduring and most valuable.
Explanation:
In this sentence, Twain explains why he believes that youth is a good time to learn moral values. After explaining that he has some things to say to children, he argues that it is during these years that such moral knowledge starts to take root in a person. He also believes that the things we learn during these years are the most enduring and most valuable in our future lives.
Which statement describes the 3d, 4s, and 4p orbitals of arsenic (as) based on its electronic configuration and position in the periodic table?.
The statement that describes the 3d, 4s, and 4p orbitals of arsenic (as) based on its electronic configuration and position in the periodic table is; The 3d and 4s orbitals are completely filled, and the 4p orbital is partially filled.
The electronic configuration of arsenic is given as; 1s² 2s² 2p^(6) 3s² 3p^(6) 4s² 3d^(10) 4p³.
Now we can see that in that electronic configuration the orbitals are, s, p and D.
Now, the maximum electrons for each of the 3 orbitals are;
Maximum electrons for d orbital = 10 electrons
Maximum electrons for s orbital = 2 electrons
Maximum electrons for p orbital = 6 electrons.
Now, when we compare the maximum number of electrons for each orbital to the ones in electron configuration of arsenic, it is clear from the last 3 orbitals that the 3d and 4s orbitals are completely filled while the 4p orbital is half filled or partially filled.

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. The only problem is that you do not know what element will form. By your previous calculations you know that you will have 6. 3 moles of product. When it is complete, you weigh it and determine you have 604. 4 grams. What element have you produced?.
Answer:
molybdenum (Mo)
Explanation:
For this question you need to understand what the concept of molar mass is.
Molar mass is the exact mass by which you will obtain a mol of that specific element. For example the molar mass of H2O is 18g/mol, so it means that in 18 grams of water, you exactly have 6.022x10²³ molecules of water or one mole.
So here you know the number of moles you produce and its conversion to grams. The problem is basically stating that in 604.4 grams of x element you have 6.3 moles of that element.
All you have to do is divide the number of grams by the number of moles:
604.4grams/6.3 moles=95.94 g/moles,
You obtained the molar mass of that X element, and in fact the molar mass corresponds the molecular mass of all elements, that is an information provided by the periodic table. So all you have to do is look for the element with a molecular mass of 95.94 uma or a very close approximate.
Molybdenum has a molecular mass of 95.95. So that's the answer.
