Please answer the new questions.
Thanks in advance.
1. The probability is 0.52 that the officer will pull over a driver and then the expected number more. So, if x is the expected number of drivers pulled over until one is not texting, we have ...
... x = 0.52(1+x)
... 0.48x = 0.52
... x = 0.52/0.48 = 13/12 = 1 1/12 ≈ 1 . . . . matches selection A
(Comment on this result: I find it interesting that these are the odds in favor of finding a driver who texts. That is, if the probability of texting is 0.98, the odds are 49:1 that a driver will be texting, and the expected number of pull-overs is 49.)
2. The probability of at most 2 being cured is the probability of 0, 1, or 2 being cured. You need to add up those probabilities. The sum in answer selection B does that.
3. The mean of a binomial distribution is ...
... μx = np = 60·0.2 = 12
... σx = √(np(1-p)) = √(12·0.8) ≈ 3.0984
These match selection D.
4. 20C14(0.8^14)(0.2^6) = 38760·.043980·0.000064 ≈ 0.109100 . . . matches A
5. mean(x) = 0.94; mean(x^2) = 1.58, so ...
... σx = √(1.58 -0.94²) ≈ 0.83 . . . . matches selection B
What’s the difference between dual credit and AP courses?
Dual credit is a college course that will get you college credit if you pass the class, but AP will only give you credit if you pass the (really hard! i have taken 7) AP test and that is if your college that you want to go accept it. Many colleges only accept scores 4-5 (top scores) and many colleges do not accept most AP course credits to be transferred over.

Answer
A.Randolph’s conclusion is not correct. If the correlation coefficient is 0, there is not a linear relationship, but there could be another type of relationship.
Explanation
A value of 0 for a correlation coefficient would mean there is no association between the two variables in the test. A value greater than zero would mean a positive correlation when a rise in the values of one variable mean a rise in the value of the other variable.

Carbon monoxide has _______of oxygen.
A. one Atom
B. zero Atom
C. two Atoms
Carbon monoxide has one Atom of oxygen.
Answer: Option A
Explanation:
Carbon monoxide (co) has one atom of carbon and one atom of oxygen. The characteristics of co gas are colorless, odorless and tasteless. Inhaling of carbon monoxide is dangerous because the oxygen in the presence of blood is displaced by it, which will make you become consciousness.
In the atmosphere of Earth, only a small amount of carbon monoxide is presented. Special design of ventilation systems can be installed in areas where a large group of people assemble to avoid the co gases.

The process that keeps heat from being transffered between two substances
In fluids, heat is often transferred by convection, in which the motion of the fluid itself carries heat from one place to another. Another way to transfer heat is by conduction, which does not involve any motion of a substance, but rather is a transfer of energy within a substance (or between substances in contact).

Do you think the United States should continue to execute criminals? Why or why not
I believe that it important for The US to continue to execute criminals. This is important because we don't want criminals to be running around shooting up people and causing trouble. We are already doing a good job dealing with criminals and putting them in prison aren't we? Why should we change? This is also a big part in polices jobs, so if we didn't continue to put criminals in jail, then how to police get payed, and how do we continue to get the security we need? Know even though this is a obvious question, on the other hand people could make a counter that it takes up too much space in prisons. Know this however is a reasonable argument, we have to punish criminals somehow correct? It's essentially grounding a six year old from not doing what he/she is told. The kid has to get punished somehow correct? Just like everyone in the world should be put in their place depending on whether it's murder or something less intense. That is just how the world is. We live and learn, but of course it is unacceptable to murder, hurt, or cause any abuse or harm to someone in any way.

Iron pyrite (FeS2) is the form in which much of the sulfur exists in coal. In the combustion of coal, oxygen reacts with iron pyrite to produce iron(III) oxide and sulfur dioxide, which is a major source of air pollution and a substantial contributor to acid rain. What mass of Fe2O3 is produced from 84 L of oxygen at 3.41 atm and 148◦C with an excess of iron pyrite? Answer in units of g.
4FeS₂ + 11O₂ = 2Fe₂O₃ + 8SO₂↑
n(FeS₂) = m(FeS₂)/M(FeS₂) = 6000/120 = 50 моль
по уравнению реакции - n(O₂) = (11*n(FeS₂))/4 = (11*50)/4 = 137,5 моль
V(O₂) = n(O₂)*Vm = 137,5*22,4 = 3080 л
ответ: V(O₂) = 3080 л

Answer:
[tex] 8.297 mol O_2 *\frac{2 mol Fe_2 O_3}{11 mol O_2} *\frac{159.69 gr Fe_2 O_2}{ 1mol Fe_2 O_3}= 240.90 gr Fe_2 O_3[/tex]
Explanation:
For this case we have the following equation:
[tex] 4FeS_2 +11 O_2 \rightarrow 2Fe_2 O_3 +8SO_2[/tex]
After balance the equation.
For this case we can use the following expression for an ideal gas:
[tex] PV = nRT [/tex]
And if we solve for [tex]n_{O_2}[/tex] we got:
[tex]n_{O_2} = \frac{PV}{RT} =\frac{3.41 atm *84L}{ 0.082 \frac{atm L}{mol K} (148+273)K} =8.297 mol O_2[/tex]
The mass for the [tex] Fe_2 O_3[/tex] is given by: [tex] 55.845gr*2 +16gr*3=159.69 gr[/tex], since we have 2 molecules of iron and 3 from oxygen.
For this case since the pyrite is the excess reactive we can calculate the amount of [tex]Fe_2 O_3[/tex] with the oxygen and we can do this:
[tex] 8.297 mol O_2 *\frac{2 mol Fe_2 O_3}{11 mol O_2} *\frac{159.69 gr Fe_2 O_2}{ 1mol Fe_2 O_3}= 240.90 gr Fe_2 O_3[/tex]

《RIDDLE》 A man is stranded on an island covered in forest. One day, when the wind is blowing from the west, lightning strikes the west end of the island and sets fire to the forest. The fire is very violent, burning everything in its path, and without intervention the fire will burn the whole island, killing the man in the process. There are cliffs around the island so he can't jump off. How can the man survive the fire? (There are no buckets or any other means to put out the fire.)
The riddle is that the man can survive the fire by starting the fire which then burns out the East end as he can then take shelter in the area.

A. has properties very similar to sodium
B.has properties very similar to chlorine
C.has very different properties from sodium and chlorine
Answer:
The correct answer option is C. has very different properties from sodium and chlorine.
Explanation:
We know that salt (chemical name: Sodium Chloride) is made from two elements, Sodium (Na) and Chlorine (Cl). But the properties of the compound of sodium and chlorine has completely different properties than those of its elements: Sodium and Chlorine.
Sodium is quite a low density but highly reactive silvery white metal and Chlorine is a highly reactive greenish yellow gas. While salt (NaCl) is a crystalline material, white in color, which readily dissolves in water and is used as a condiment to add flavor to food.

The probability that "at most 1" will be cured is the probability that 0 or 1 will be cured. The attachment shows how that is calculated.
[tex]\binom{18}{0}(0.7)^{18}+\binom{18}{1}(0.3)^1(0.7)^{17}[/tex]
This will be a binomial probability, since there are two options - either cured or not cured.
We want the probability that less than or equal to one person is cured. This means we want the probability that either 0 people are cured or 1 person is cured.
To find the probability of 0 people being cured, we take a combination of 18 people chosen 0 at a time:
[tex]\binom{18}{0}[/tex]
We multiply this by the probability of someone being cured, 0.3, raised to the number of people being cured, 0:
[tex]\binom{18}{0}(0.3)^0\\\\=\binom{18}{0}(1)=\binom{18}{0}[/tex]
Lastly we multiply this by the probability of someone not being cured, 1-0.3, raised to the number of people not being cured, 18:
[tex]\binom{18}{0}(1-0.3)^{18}\\\\=\binom{18}{0}(0.7)^{18}[/tex]
To find the probability of 1 person being cured, we take a combination of 18 people chosen 1 at a time:
[tex]\binom{18}{1}[/tex]
We multiply this by the probability of someone being cured, 0.3, raised to the number of people being cured, 1:
[tex]\binom{18}{0}(0.3)^1[/tex]
Lastly we multiply this by the probability of someone not being cured, 1-0.3, raised to the number of people not being cured, 17:
[tex]\binom{18}{0}(0.3)^1(1-0.3)^{17}\\\\=\binom{18}{0}(0.3)^1(0.7)^{17}[/tex]
"Almost every year, from 1581 onward, the mariners of the Netherlands strove, by east and by west, to pass the barrier that America interposed between them and the Eastern trade they coveted … They would not be hurried; they took their time to think it over, as Dutchmen will; but at length they conceived an immense project for acquiring all the trade, or the best part of it, of both the West and the East … In 1609, quite inadvertently, Henry Hudson discovered it … received a visit from some Indians with native commodities to exchange for knives and beads … They were affable, but untrustworthy, stealing what they could lay their hands on, and a few days later shooting arrows at a boatload of seamen from the ship, and killing one John Colman. Hudson went ashore, and was honored with dances and chants; upon the whole, the impression mutually created seems to have been favorable."—Julian Hawthorne, from The History of the United States from 1492 TO 1910, V1 Which of the following is an example of how the English interacted differently than the Dutch in regards to American Indians? The English had the best and most enduring relationships with American Indians. The English introduced slavery of American Indians and Africans. The English saw American Indians as trade partners and allies. The English saw American Indians as obstacles to profiting from the new land.
