Two presidential candidates in a televised debate were asked to state their qualifications. Candidate Barry Smithers replied, “I am well qualified for the position of president of this great land. I have worked hard to ensure that voters’ concerns were heard, and their voice was unanimous: We need more jobs and a cleaner environment. I have a vision that this nation can come together to accomplish these goals.” Candidate Joe O’Neal answered, “I have a record of experience that makes me well qualified for the role of president, as shown by my term as governor and my 20 years of service in the U.S. Senate. I voted for a bill that has created jobs by building and repairing public roads and buildings. I have voted to ensure cars were manufactured to reduce greenhouse gas emissions.” Which of the candidates has presented a stronger demonstration of his or her qualifications, and why? Candidate Barry Smithers, because he listens to the concerns of voters, unlike his opponent Candidate Joe O’Neal, because he stated evidence of his service record, unlike his opponent Candidate Barry Smithers, because he says he has a vision for success that his opponent lacks Candidate Joe O’Neal, because he believes in creating more jobs, in contrast to his opponent

we know it takes 31 workers to do a car, and 19 to do a motorcycle… so hmmm to make “c” cars, it will then take 31*c workers, or 31c

to make “m” motorcycles, it will then take 19*c or 19c employees

whatever those amounts of workers needed to make both, must be an amount that is 706 or less, thus

31c + 19m ⩽ 706

now…. it takes $7500 to make a car and thus to make “c” cars it will then take 7500* c or 7500c

it takes $4300 for a motorbike, thus to make “m” motorbikes, it will then take 4300*m, or 4300m

whatever those dollar amounts are, must be 84000 or more, since Genghis Motors wants to spend that OR more

7500c + 4300m > 84000

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies.

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface.

m₁=10 g=0.01 kg is the mass of the pencil

m₂=20 g=0.02 kg is the mass of the eraser

r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h.

So the time for the pencil and eraser to touch is T=1.3449 hours.

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

**Answer:**

**In Washington D.C., we visited three museums in a single day : the National Portrait Gallery, the Freer Gallery of Art, and the National Museum of Natural History.**

**Explanation:**

The correct rewriting of the sentence will be –

**In Washington D.C., we visited three museums in a single day : the National Portrait Gallery, the Freer Gallery of Art, and the National Museum of Natural History.**

The use** **of the comma right after Washington is wrong as it is the name of a single particular place so it should instead be written as Washington D. C.

Also, a semicolon has to be inserted in between day and the. Since the sentence lists a number of places, the use of a colon is necessary to show the list of the places visited.

So, the changes in the sentence are-

**(a) remove the comma (,) in between Washington and D.**

**(b) put a colon (:) right next to the word “day”.**

**Answer:**

The Fourth of July parade included the following floats, which all had a patriotic theme** :** marching bands, clowns, jugglers, and other circus performers

__and antique cars, trucks, and other vehicles.__

**;****Explanation:**

**Colons**‘ function is to introduce an item or a series of items when they are preceded by a complete thought (sentence), such as it is used in the sentence **“The Fourth of July parade included the following floats, which all had a patriotic theme:”** which it’s a complete thought.

As for **commas**, one of their functions is to separate items in a list such as in **“marching bands, clowns, jugglers, and other circus performers”. **

Likewise, **semicolons** can also be used to separate items in a list when the list items already contain commas. In this case, semicolons are used to show which items are grouped together, and to outrank the existing commas, such as it is employed in the following list: **“marching bands, clowns, jugglers, and other circus performers; and antique cars, trucks, and other vehicles.”** Here, the semicolon works as a separator of the two lists.

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

The Contribution Margin per unit (CM) can be calculated

from the difference of Selling Price per unit (SP) and Total Expenses per unit

(TE).

First, let’s calculate the value of SP:

SP = Sales / Units sold

SP = $1,043,400 / 22,200 units sold

SP = $47

Second, calculate all expenses:

Direct materials per unit = $234,948 / 27,970 units

manufactured = $8.4

Direct labor per unit = $131,459 / 27,970 units

manufactured = $4.7

Variable manufacturing overhead per unit = $240,542 / 27,970

units manufactured = $8.6

Variable selling expenses per unit = $113,220 / 22,200

units sold = $5.1

TE = $26.8

Therefore the CM is:

CM = SP – TE

CM = $47 – $26.8

**CM = $20.2 per unit**

So, from that basic knowledge you can analyze each option:

**a.Lines s and t have slopes that are opposite reciprocals.**

**TRUE. Tha comes the number 2 basic condition for the perpendicular lines.**

slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.

**c.The product of the slopes of s and t is equal to -1**

**TRUE: that is one of the basic statements that you need to know and handle.**

d.The lines have the same steepness.

FALSE: the slope is a measure of steepness, so they have different steepness.

e.The lines have different y intercepts.

FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.

f.The lines never intersect.

FALSE: perpendicular lines always intersept (in a 90° angle).

**g.The intersection of s and t forms right angle.**

**TRUE: right angle = 90°.**

h.If the slope of s is 6, the slope of t is -6

FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.

O ……………… 3 lone pairs on terminal O

I didn’t show the second of two resonance structures in which the single and double bonds are reversed. In reality, both bonds are identical have a bond order of 1.5 due to delocalized pi-bonding.

The central atom exhibits sp2 hybridization since there is trigonal planar electron pair geometry. The notion of hybrid orbitals was “invented” by Linus Pauling in the 1930’s as a way of explaining the geometry of molecules, primarily the geometry of carbon compounds.

If the electron pair geometry is linear, the hybridization is sp.

If the electron pair geometry is trigonal planar, the hybridization is sp2.

If the electron pair geometry is tetrahedral, the hybridization is sp3.

The notion that there is sp3d and sp3d2 because of d-orbital participation has been debunked. Chemists know today that there is no d-orbital involvement in hypervalent molecules regardless of what some out-of-date textbooks and some teachers’ dusty old notes may say. Instead, the best explanation involves 3-center, 4-electron bonding.

**“I, Too” by Lansgton Hughes:****1, 6**

**1-** This poem is a reference, and a sort of answer, to Whitman’s poem “I Hear America Singing.” In his poem, Whitman talks about how every American -mechanics, carpenters, boatmans- is singing. However, he makes no mention of black people. This is why the poem is entitled “I, Too,” to express that Hugues, an African American man, is still an American.

**6-** This poem does not have specific rhyme scheme or meter. Therefore, it is written in what is known as “free verse.”

**“****From the Dark Tower” by Countee Cullen:****2, 3, 4, 5**

**2- **The social injustice paradox means that social injustice is rooted in the lack of access to education, money and power, and that the solution lies in institutions which are always supported by those with money and power. This poem refers to this paradox because it refers to white people oppresing African Americans and not allowing them to be rightfully repaid for their work.

**3- **This poem is written in iambic pentameter and has a traditional (ABAB) rhyme scheme.

**4- **The poem symbolizes the great efforst black people did while working, only to have their profits taken by their white maters.

**5- **The whole poem is filled with an angry tone. Lines such as “Not always bend to some more subtle *brute*;” clearly express the resentment and repudiation she feels for white people.

**1. Scatter plot :** In Scatter plot, which consist of two variables, are represented in two dimensional plane through dots.If you join these points along the order in which they are given , you can’t predict whether they are in ascending or descending order.But if you arrange the data in ascending order and then plot it on two dimensional plane, you will get numerical data in ascending order.

**2. Line Graph: **A line graph is representation of something over a period of time. Suppose an object is not moving uniformly, we plot distance traveled in different interval of time in two dimensional coordinate plane.As Distance traveled is always positive , with increase in time , distance traveled will increase or remain constant , for two duration or period. So, we can say with conformity that Line graph is also one of the simplest way of representation of numerical data in ascending order.

**3. Box-and-whisker plot: **In Box and whisker plot, when data is arranged in ascending order, then a box is drawn, the upper and lower ends of box are first Quartile and third Quartile Respectively.Median lies inside the box.The spanning of whole box tells about Interquartile range.And the two line segments which are connected from the two ends of box ,one end of segment is lowest value in Data set and Other end of segment is largest observation in the data set.In Box and whisker Plot, Numerical data is also arranged in ascending order.

**4. Stem and Leaf Plot: **In Stem and Leaf plot, data is splitted into parts, the first digit of number from left is stem and last digit from right is Leaf.

For, example 45,46,47,……

4 is Stem and 5,6,7 are Leaves.

So, the way of representation of numerical data, is simplest in stem and leaf plot.

**Option D:Stem- and- Leaf Plot , **is simplest method to represent numerical data in ascending order.

The American participation in the Vietnam War was very different from its involvement in the Bay of Pigs Invasion.

In the Vietnam War, the United States carried out direct participation, with first-hand military planning and execution and large-scale attacks. Some 60,000 Americans died in the conflict, of about one million who participated.

In contrast, in the Bay of Pigs Invasion, American participation was indirect. That is, the attack was planned and the troops trained by American forces, but these were made up of Cuban exiles, not American soldiers. In addition, it was a small-scale attack, both because of the low number of men involved and because of its short duration.

**1. Trip planning helps reduce “driving distance and stress”.
**

Trip planning helps reduce Driving distance and stress. We can pre-plan the trip how to go, where to go first, from where the spot is close and what the spots to be seen there and the aggregate estimation for the trip.

We as a whole need to travel around and see things yet it all conceivable just on the off chance that we keep up few hints identified with trip. The initial phase in arranging an excursion is to choose where you need to go and what you’d get a kick out of the chance to see.

**2. A pre-trip inspection will help you “find problems that could cause a collision or breakdown”.
**

The pre-trip inspection is a vital piece of each trip. It is intended to be an exhaustive check of the semi-truck, trailer and load, to guarantee that everything accurately, before the truck driver, leaving on a trek. Any harm or issues requiring consideration, are to be tended to before departure. The motivation behind a pre-trip review is to check the working state of your vehicle. When you direct an appropriate assessment, you are surveying the mechanical and wellbeing parts of your truck, for example, Brake framework.

**3. When you hear or see the warning signal of any emergency vehicle, you should “pull over to closest edge of the road”.
**

You should yield the right-of-approach to flame, rescue vehicle, police and other approved emergency vehicles when they react to crises. They will show lights that are blazing red, red and blue or red and white and sound an alarm or air-horn. When you hear or see an emergency vehicle making a beeline for your vehicle from any course, securely pull over instantly to the right edge of the street and stop. Hold up until the point that the crisis vehicle goes before you drive on. In the event that you are in a crossing point, drive out of it before you pull over.

**4. In order to reduce stress when traveling, you should avoid “rush-hour traffic”.
**

No one enjoys sitting in rush hour traffic. We endeavor to locate the most ideal approaches to keep away from it. There are sure circumstances of the day when more vehicles are on the streets, for the most part individuals going to work or school in the mornings and individuals heading home in the nights, so attempt to maintain a strategic distance from rushy hours. Before you go on any trip, design out your course so you can maintain a strategic distance from any street development or other congested driving conditions.

**5. Before you leave for a trip, you should check “tire condition, vehicle lights, fuel gauge”.
**

It’s imperative to dependably check tire weight before taking off on a long outing or while conveying additional load. Driving on tires with inappropriate swelling weight is perilous and can cause tire harm and in addition influence the vehicle’s ride, dealing with and fuel economy. Take a minute to nearly examine the condition of your tires. Check for any cuts, breaks, parts or wounds in the tread and sidewall territory. Likewise ensure the front and back lights, brake lights, pointers and hazard lights work. You ought to do this each time you utilize the vehicle.

Question 1:

Because we start with the year 2000, we must subtract 2000 from 2015 giving us t= 15 years.

Question 2:

Like Question 1, we must subtract 2000 from 2010, giving us t=10 years. We then plug t=10 into the first equation, giving 1.5*10+42, which equals 57. Then because this number is in thousands of dollars, we know that the average income is equal to 57,000 dollars.

Question 3:

For this problem, we can use the same value for t as we used in Question 2, t=10 years, because we are dealing with the same date, 2010. We then plug this value of t into the second equation, giving 0.3*10+8.4, which equals 11.4. We then multiply this number by 1 million because this number is in millions of people giving an answer of 11,400,000 Hispanic people in 2010.

Question 4:

We must take the number 11,400,000. from Question 3 and put this into scientific notation by moving the decimal point to the left until there is only one number of the left side of the decimal point and multiplying our result of that by 10 to the power of how many places we moved the decimal point, giving us 1.14*10^7(^ means to the power).

Question 5:

The total income of all Hispanic families is going to be equal to the number of total Hispanic families (0.3t+8.4) times the income of one average Hispanic family (1.5t+42). However, we first must recognize that the formula for the number of Hispanic families is in millions, but the formula for the average income of one Hispanic family is in thousands. Since thousands is less than millions we will change both will change the formula for the number of Hispanic families to thousands by multiplying the first equation by 1000. This gives us an a new equation of 300t+8400 for the number of Hispanic families in thousands. Now we can multiply the two equations together using the FOIL Method (First, Outer, Inner, Last). This gives us a resulting equation of (1.5t*300t+42*8400+42*300t+8400*1.5t). When we multiply out these terms, we get (450t^2+352800+12600t+12600t). Since there are multiple terms with the same power of t, we can combine like terms and condense the equation to 450t^2+352800+25200t. Since there are some pretty big numbers in this equation, we can divide the whole equation, which is in thousands, by one thousand, which in turn will make the equation in millions. This yields (.45t^2+352.8+25.2t) in millions. This is the equation for the total income of all Hispanic families in a given year after the year 2000 where t is equal to the current year minus 2000.
