Answer:

∠W = 130∠X = 140∠Y = 50∠Z = 40

Step-by-step explanation:

Using 'y' and 'z' to represent angles with the corresponding names, we have ...

  y + z = 90

  (3b -1) +(2b +6) = 90 . . . . substitute the given expressions

  5b +5 = 90 . . . . . . . . . . . . simplify

  b +1 = 18 . . . . . . . . . divide by 5

  b = 17 . . . . . . . . subtract 1

Then the angles are ...

  y = 3b -1 = 3(17) -1 = 51 -1 = 50

  z = 2b +6 = 2(17) +6 = 34 +6 = 40 . . . . note that these are complementary, as theys should be

Angles W and Y form a linear pair, so are supplementary:

  W = 180 -Y = 180 -50 = 130

Angles X and Z form a linear pair, so are supplementary:

  X = 180 -Z = 180 -40 = 140

Then the angle measures are ...

∠W = 130∠X = 140∠Y = 50∠Z = 40

The NEC permits 20% of the cross sectional area in a wireway to be occupied by conductors.for an 8"×8"×6' long wireway the conductors can occupy. In squared?

Answers

Answer:

Step-by-step explanation:

Sjaoa

The required cross-sectional area in a wireway is 12.8 In squared.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

We have been given an 8"×8"×6' long wireway the conductors can occupy.

Since the NEC permits 20% of the cross-sectional area in a wireway to be occupied by conductors

So the required cross-sectional area in a wireway is

⇒ 20 % of ( 8"×8" )

⇒ 0.20 × (64 )

⇒ 12.8 In squared

Thus, the required cross-sectional area in a wireway is 12.8 In squared.

A political scientist wants to estimate the percent of registered voters in Florida who plan to vote for a particular candidate. The political scientist interviews 4000 randomly selected registered voters in Florida and asks who they plan to vote for. 58% say they plan to vote for the candidate. Which of the following statements is true?

a. 58% is a parameter because it describes a population characteristic.
b. 58% is a statistic because it describes a sample characteristic.
c. 58% is a statistic because it describes a population characteristic.
d. 58% is a parameter because it describes a samic characteristic.

Answers

Answer:

b.) 58% is a statistic because it describes a sample characteristic.

Step-by-step explanation:

The randomly selected 4000 voters represents a randomly selected observations from the population of registered voters

Hence, 4000 is a sample.

The percentage of voters who would vote for a particular candidate represents a numerical characteristic derived from the sample drawn.

Recall that, numerical characteristics or values which are calculated from the sample is known as statistic while those derived from the population are called parameter.

Hence, 58% is a statistic as it describes a sample characteristic.

You can use definition of parameter and statistic and then can use them to find what does 58% denotes here.

The true statement is given by:

Option B: 58% is a statistic because it describes a sample characteristic.

What is a population and parameter?

The entire group or system which we are taking in consideration is population. Nothing bigger than it lies there in consideration.

Ex: If we're taking about health problem in a country, then the whole country people form a population.

If we're taking about numbers on a 6 face die, then those 6 numbers on 6 faces form a population.

Those numbers who summarize information about population are called parameter.

What is sample and statistic?

A portion of population taken and analyzed to predict information about population is called sample of that population.

Ex: When someone surveys a group, then he/she surveys a portion and not whole population in general.

Those numbers who summarize information about sample are called statistic.

(Statistic is different than statistics)

Using above definitions to conclude what 58% refers to

Since the 58% is from the 4000 people randomly selected by the political scientist, thus, it is information about sample and thus, is a statistic.

Thus,

The true statement is given by:

Option B: 58% is a statistic because it describes a sample characteristic.

You are looking at a pair of parallel lines (a and b) and a transversal that crosses them both.

Now that you know what think back to when you learned the relationship between angles formed by a transversal and a set of parallel lines.

You can have same side exterior, same side interior, alternate interior and alternate exterior. Which set of these are these angles?

Remember same side interior and same side exterior angles are supplementary (they have a sum of 180 degrees). Alternate interior and alternate exterior angles are congruent. Knowing this how can an equation be written using the expressions in the image?

Step-by-step explanation:

Answer:

x = 3.4

Step-by-step explanation:

Since these two angles are opposite exterior angles, they are equivalent. that means that 5x - 2/3 = 3 1/3x + 5, from here you should simplify the terms so you have all of x on one side and all of the number on ther other, it should be 1 2/3x = 5 2/3, then all you have to do is divide both sides by 1 2/3 to get x which is 3.4 or 3 2/5

Mia takes a random sample of 10 of her coworkers and asks them each how many pets they have. Assume that
their results are independent, and let X represent the average number of pets in the sample.

Answers

Answer: Each trial isn’t being classified as a success or failure, so X is not a binomial variable.

Step-by-step explanation:

X is not a binomial variable since each trial is not categorized as a success or failure.

What is a binomial variable?

The likelihood of failure increased to the power of the difference between the number of successes and the number of tries is multiplied by the chance of succeeding raised to the power of the number of successes.

The chance of success for the trials in question in a binomial distribution must stay constant. Because there are only two possible outcomes when flipping a coin, the likelihood of doing so is 0.5 for each trial.

Since lX indicates the typical number of pets in the sample and their outcomes are independent, X is not a binomial variable.

Both effectively changed the popular opinion about emotional issues for their countries and brought in a wave of change that was long overdue. But the practice of non-violent protest, or civil disobedience, started long before either Gandhi or King. It began with a quiet, shy poet who is best known for writing a lot about a pond. Henry David Thoreau lived from 1817 until 1862, mainly in the area of Concord, Massachusetts. The issue that would tear the country apart in the 1860s had already begun dividing the nation. Thoreau was only 14 when Nat Turner led the slave rebellion in Virginia and was later hanged. In his late 20s, Thoreau began speaking against slavery in public, echoing the voices of freedmen like Frederick Douglass and Lewis Hayden. Thoreau believed that a government that supported slavery was corrupt and immoral. He was also deeply suspicious of government. For these and other reasons, Thoreau refused to pay his poll tax for a number of years. The poll tax was a legal tax owed by every person. It was basically a tax on one's body. After not paying for years, he was at last arrested. He spent only one night in jail, however, as a relative paid the tax for him. He was reportedly furious that any tax was paid on his behalf. It was this experience that Thoreau wrote about in an essay called "Civil Disobedience." In this essay, he argued that being moral and just came before allegiance to government. He wrote If the machine of government is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law." He also felt that voting was not enough to ensure that the right thing be done. He wrote that "even voting for the right is doing nothing for it A wise man will not leave the right to the mercy of chance" He felt that one had a moral responsibility to resist unjust laws.

All my college friends were going, and we decided to dress for the theme, complete with headbands, leg warmers, blue eyeshadow, and teased hair. The night of the party, everyone looked great and we all had a good time.Then I decided to show off. About ten minutes before the party ended, I started trying moves I learned long ago when I dreamed of being an Olympic figure skater. I actually had never been good enough on the ice to get anywhere near the Olympics, but I loved skating and was pretty decent at one point. There I was at the party, spinning, twirling, and skating backward. Then I decided to bring my friend Heidi in on the fun, so I grabbed her hands and pulled her along with me as I skated backward. I was smart enough to be looking behind me to make sure I wouldnt bump into anyone, but I was not smart enough to pay attention to my balance, which I lost.I fell down onto the newly buffed rink floor. Before I knew what was happening, Heidi tripped and fell on top of me, and I heard a crack. I remember feeling the wind get knocked out of me, and then a rush of faces looking down asking if I was okay. My friend Kathleen, who was studying to be a nurse, asked questions to make sure I wasnt seriously injured, and another friend called an ambulance. Since I was not yet feeling any pain, the sheer embarrassment of the moment was my main focus.In the hospital I learned that I had broken a rib and fractured my collarbone. Kathleen had come with and assured me that I was lucky: it could have been much worse. Looking back, I have to laugh at the reaction we got from the hospital staff. Every time a new doctor or nurse walked into my room, we felt the need to explain our getups. The explanation was generally met with blank stares from people who had much more pressing concerns than what the girl in Room 3 was wearing.I went home with strict instructions to move as little as possible for the next few weeks. Lucky for me, I was on summer break so I didnt have to worry about school. Id been planning to stay in my off-campus apartment and work that summer. Instead, I took a leave of absence from my job, formed a stack of books Id been meaning to read for ages, and settled in for what would surely be some of the most boring weeks of my life. The next day, Heidi called and apologized profusely for falling on me. I thanked her but pointed out that it had been my fault that I ended up getting hurt.Even so, we all feel terrible that you ended up in the hospital at the end of a great party, Heidi said. Listen, I called a bunch of people who were there and asked if they wanted to volunteer for a meal drop-off schedule. I have your breakfast, lunch, and dinner covered for the next three weeks. I needed a moment to process what Heidi was telling me. Next to my stack of books was a stack of menus from which Id planned to order all of my food for the next few weeks. The thought of an all-fast food diet had made me a little nauseous, but I knew I wouldnt be able to cook. Now my friends were coming to my rescue.Starting the next morning, in addition to bringing amazing home-cooked meals, as well as some great take-out, my friends took turns visiting me so I didnt get lonely. Those weeks ended up flying by. Before I knew it I was up and about again.Eventually, my friends let me in on what a good laugh they had the night of the party once they knew I was going to be all right, of course. As soon as my rib and collarbone healed I had a pretty good laugh about it, too. I didnt mind that they had laughed. I decided that any group of friends willing to cook for me during summer break was allowed to laugh at me.Which excerpt from the story supports the inference that the narrator was not planning to ask for any help during her recovery?I thanked her but pointed out that it had been my fault that I ended up getting hurt.Next to my stack of books was a stack of menus from which Id planned to order all of my food for the next few weeks.I took a leave of absence from my job, formed a stack of books Id been meaning to read for ages, and settled in for what would surely be some of the most boring weeks of my life.Since I was not yet feeling any pain, the sheer embarrassment of the moment was my main focus.
