Answers

The equation that best represents a the given situation is: 3n + 3 = 303., as found by number system.

What is number system?

A system of writing numbers is known as a number system. It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set. It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.

Given: Sum of three consecutive integers is 303.

n = smallest integer.

According to question, the other two integers are: n + 1, and n + 2.Since the sum of the three consecutive integers is 303, addition operation on the values of number system

n + n + 1 + n + 2 = 303

3n + 3 = 303.

Hence, The equation that best represents a the given situation is:

A truck can be rented from Company A for $40 a day plus $0.30 per mile. Company B charges $20 a day plus $0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.​

Answers

The number of miles in a day at which the rental costs for Company A and Company B are the same is 200 miles per day

Let the truck is driven X miles per day

Charges of company A will be = 90+0.4X

Charges of company B will be =30+0.7X

Let us find out value of X when charges of both companies are same

which means that   90+0.4 X= 30+0.7X

                            90-30      = 0.7X-0.4X

                            60    = 0.3X

                             60/0.3 = X

                             X= 200

The charges of both companies will be same if truck is driven 200 miles per day

Company A will have better deal if truck is driven more than 200 miles per day ( because per mile rate of company A is less than company B)

Answers

Bill is better bowler than George.

To decide who's the relative better bowler, George or Bill, I've first drawn bell curves for each of their leagues. George's league is in red mean is 150 a standard deviation of 20. And Bill's League Demean is higher at 160, but the standard deviations it is lower at 15, so I've numbered my bell curve by 15.

Now to decide who's relative better bowler, I'm going to calculate their Zscores for George, His observed value is 180, which would fall right here on our number line, and his Z score is gonna be 180- the mean. So he's 30 points above the mean, Divided by the standard deviation (180-150)/20=1.5 And then for bill, we're going to do the same thing. His score is also, let's see here his score is 190,(190-160)/15=2And you can probably see just by marking that on the bell curve, that that's actually two standard deviations above the ME, which is more than George is 1.5 standard deviations above the mean. So we can say that Bill is better bowler.

Answer:

Answers

The value of x is ±√(42 -  y² - z²).

What is equation?

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.

Given:

x² + y² + z²=k

As, it is given that k = 42.

So, x² + y² + z²=k

x² + y² + z²= 42

x² = 42 -  y² - z²

x=±√(42 -  y² - z²)

Hence, the value of x is ±√(42 -  y² - z²).

Answer:

Step-by-step explanation:

We can solve this equation by taking the natural log of both sides.

This gives us the equation: [tex]ln(e^{3x})=ln(12)[/tex]

And the definition of natural log is basically, "what do I have to raise e to, to get this result"

The result is just e^3x, so I have to raise e to what? Well that's just 3x, you could also use log properties to bring the exponent in front and realize ln(e) = 1

So this gives us: [tex]3x=ln(12)[/tex]

Now divide both sides by 3: [tex]x=\frac{ln(12)}{3}[/tex]

ASP 50Hello! Please read these theories on How the Native Americans Migrated. Choose one and tell me why you agree with it.First TheoryArcheologists have thought they knew how ancient humans arrived on the American continentfor about the past 50 years. As of 2008, genetic findings are suggesting that a single populationof modern humans migrated from southern Siberia toward the land mass known as the BeringLand Bridge as early as 30,000 years ago, and crossed over to the Americas by 16,500 years ago.Archaeological evidence shows that by 15,000 years ago, humans had made it south of theCanadian ice sheets. As the ice caps in Canada began to melt, a path southward emerged.Archeologists call these people Clovis, after some stone tools from the era were found nearClovis, New Mexico in the 1920s and 1930s . This may be the earliest migration the scientistshave uncovered but it certainly isnt the only one.Second TheoryFrom the 1930s all the way to the 1990s. The Clovis people were thought to be the onlymigration theory. In 1997, archeologists made a discovery of an archaeological site in MonteVerde, Chile, dating back to 14,500 years ago - a full millennium older than what was previouslythought to be the first people in the new world, and indicating they settled much further souththan expected. These new finding sparked much debate about the first humans migrating to theAmericas. Many new questions were asked. Did they in fact come across the Bering LandBridge? Could they have arrived in South America via a different route?Intense criticism also rained down on competing theories of how people arrived, such as the ideathat early Americans might have skirted the coastline in boats, avoiding the Bering land bridgeentirely. I was once warned not to write about coastal migration in my dissertation. My advisersaid I would ruin my career, says Jon Erlandson, an archaeologist at the University of Oregon inEugene.Third TheoryThe Third theory is viewed as the more radical theory. This theory claims it is possible that thefirst Americans didn't cross the Bering Land Bridge at all and didn't travel by foot, but rather byboat across the Atlantic Ocean. Though the evidence for this theory is minimal, proponents arguethat the artifacts were developed by an earlier and still more ancient European group, known asthe Solutrean culture. This style bears an uncanny resemblance to that of the Clovis tools foundin the United States, which could suggest that humans may have entered America from the eastover a route that has been dubbed the Atlantic Maritime route. This theory looks at writing andlanguage of the time. Many scientists claim the people of the time had similar characteristics totribes in Australia and Southeast Asia. Support for this idea is found partially in the discovery ofa 9,500-year-old skeleton in Washington State. Dubbed the "Kennewick Man," the skeletonbears a strong physical resemblance to the Japanese Ainu people, suggesting that a pan-Pacificjourney via boat might have brought the first Americans to our shores. a court issued a section 213 warrant in connection with the search of an envelope that had been mailed to a target of an investigation. the search confirmed that the target was operating a hawala money exchange that was used to funnel money to the middle east, community care center has 200 beds. it has an average length of stay of years. most of the patients are elderly, but there are some younger patients with serious chronic illnesses. community care center is most likely a(n) facility.
