explain the reasons to immigrating from the 1800s to canada to immigrating to canada today

Answers

Answer:

mmigration to New France (16th–18th Century)

Throughout the 17th and much of the 18th century, European colonial administrations, charged with overseeing what would become Canada, did not consider settlement a priority. French or British governments initially seemed unprepared to expend vast quantities of money or energy necessary to encourage settlement. Nor was migration to Canada popular in France or Britain. Adventurers, explorers, and particularly traders acting for British or French interests feared the interference of settlers in the lucrative trade (see Fur Trade).

Why did the Peloponnesian War start?
Athens attacked the city-state of Sparta.
The Spartan King stole the Athenian Queen.
The Corinthian King insulted the Athenian King.
Sparta and Corinth became jealous of the wealth and power of Athens

NO LINKS PLS

Answers

Answer:

The primary causes were that Sparta feared the growing power and influence of the Athenian Empire. The Peloponnesian war began after the Persian Wars ended in 449 BCE. ... This disagreement led to friction and eventually outright war. Additionally, Athens and its ambitions caused increasing instability in Greece

Corinth and Sparta grew envious of Athens' wealth and authority. As a result, choice (D) is the right reaction.

What is the Peloponnesian War?

The Peloponnesian War was a conflict in ancient Greece between Athens and Sparta, along with their respective allies, over control of the Greek world. Long before the Persian Empire's decisive intervention in favor of Sparta, the outcome of the conflict remained uncertain. The Spartan fleet, led by Lysander, finally destroyed Athens with the aid of Persian subsidies, ushering in an era of Spartan control over Greece.

Traditionally, historians have divided the war into three halves. The first phase, which lasted from 431-421 BC, was known as the Ten Years War, or the Archidamian War, after the Spartan king Archidamus II, who led repeated invasions of Attica with the entire hoplite force of the Peloponnesian League, the alliance system that was ruled by Sparta.

Hence, option (D) is accurate.

Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.


y = 6.22 e1.39x

y = 20.14 + 13.36 ln x

y = 11.11x0.855

y = 9.56 + 5.66x

Answers

Answer:

i)

Find the attached

ii)

The mathematical model that best fits the data is;

y = 7.19 + 12.8 ln x

Step-by-step explanation:

i)

A scatter-plot can easily be constructed using applications such as Ms. Excel and Stat-Crunch.

In Ms. Excel we first enter the data in any two adjacent columns. Next, highlight the data, then click the insert ribbon and select the scatter-plot option.

Excel returns a scatter-plot chart as shown in the attachment below.

ii)

After obtaining the scatter-plot, we shall need to add a trend line in order to determine the mathematical model that best fits the data given.

Click anywhere inside the chart, then select the design tab under chart tools. Click on the Add Chart element in the upper left corner of the excel workbook and select more trend-line options. This feature will enable us to fit any trend-line to our data.

Select any trend line option ensuring you check the boxes; Display Equation on chart and Display R-squared value on chart.

Find the attached for the various trend-lines.

The mathematical model that best fits the data is;

y = 7.19 + 12.8 ln x

Since it has the largest R-squared value of 0.9905

The regression equation of the table of values is y = 9.56 + 5.66x

How to draw the scatter plot?

The table of values is given as:

x: 0.2 0.7 1.9 3.5 7.7

y: 3        5 35   37   47

See attachment for the scatter plot based on the above table of values

How to determine the regression equation?

To do this, we make use of a graphing calculator with the following calculation summary:

Sum of X = 14Sum of Y = 127Mean X = 2.8Mean Y = 25.4Sum of squares (SSX) = 36.48Sum of products (SP) = 206.4

The regression equation is represented as: y = a + bx

Where

b = SP/SSX = 206.4/36.48 = 5.66

a = MY - bMX = 25.4 - (5.66*2.8) = 9.56

So, we have:

y = 9.56 + 5.66x

Hence, the regression equation of the table of values is y = 9.56 + 5.66x

Is it ethical for companies to advertise to children so heavily? Why or why not?
Is it ethical for companies to use ads that ask people to buy things that are unhealthy? Why or why not?
Is it ethical for companies to use images that are intended to manipulate the audience into thinking a luxury is necessary? Why or why not?

Answers

i’d say all are ethical it’s just they’re way of selling products. 1. advertising to children so heavily is a way of getting parents to buy the product, if a child is begging a parent for some product they seen on television most likely they will. 2. most people like unhealthy things/ junk food (i’m guessing this is about food) the more you see an advertisement about a restaurant and the food looks good the more you’re going to want to eat there. 3. manipulating audiences is a good way of selling products, doesn’t matter if it’s pretty people just buy luxury items to brag how much it was or that they have the item.

It is not ethical for companies to advertise to children so heavily. The American Academy of Pediatrics claims that too much exposure to marketing might encourage kids to smoke, drink, and eat poorly, which frequently results in obesity. Children are told by the advertising that they must have certain things in order to be happy and acceptable.

Why is advertising to children particularly troubling to ethicists?

Constantly exposing young children to complex marketing content may cause them to develop negative societal ideals like consumerism and materialism.

Children have little to no money of their own and must convince their parents to purchase things on their behalf, hence advertising to kids is unethical. Companies employ a "nag and complain" technique that fosters resentment between parents and children rather than directly marketing to parents.
