Answers

Answer:

 [tex]M' =(-1,7)[/tex]

[tex]N' =(-1,-4)[/tex]

[tex]O' =(-4,4)[/tex]

[tex]P' =(-4,7)[/tex]

Step-by-step explanation:

Given

[tex]M = (-7, 1)[/tex]

[tex]N = (4, 1)[/tex]

[tex]0 = (-4, 4)[/tex]

[tex]P = (-7, 4)[/tex]

Line: [tex]y = -x[/tex]

Required

The coordinates of M'N'O'P'

The rule for reflection over [tex]y=-x[/tex] is : [tex](x,y) \to (-y,-x)[/tex]

So, we have:

[tex]M = (-7, 1)[/tex]  [tex]\to M' =(-1,7)[/tex]

[tex]N = (4, 1)[/tex] [tex]\to N' =(-1,-4)[/tex]

[tex]0 = (-4, 4)[/tex] [tex]\to O' =(-4,4)[/tex]

[tex]P = (-7, 4)[/tex] [tex]\to P' =(-4,7)[/tex]

So, the points are:

[tex]M' =(-1,7)[/tex]

[tex]N' =(-1,-4)[/tex]

[tex]O' =(-4,4)[/tex]

[tex]P' =(-4,7)[/tex]

The mean age at which the population of babies first stand without support is normally distributed with a mean of 13.20 months with a standard deviation of 2.00 months. What is the probability of randomly selecting a sample of 25 children who stood on their own by the average age of 12.2 months or earlier

Answers

Answer:

0.00621

Step-by-step explanation:

We solve the above question using the

Z score formula. This is given as:

z = (x-μ)/σ/√n

where

x is the raw score = 12.20 or earlier

This means x ≤ 12.20

μ is the population mean = 13.20

σ is the population standard deviation = 2

n is the random number of samples = 25

z = 12.2 - 13.2/2/√25

z = -1/2/5

z = -1/0.4

z = -2.5

Probability value from Z-Table:

P(x≤ 12.2) = 0.0062097

Approximately = 0.00621

Therefore, the probability of randomly selecting a sample of 25 children who stood on their own by the average age of 12.2 months or earlier is 0.00621

One kilogram is approximately 2.2 pounds. Write a direct variation equation that relates x kilograms to y pounds.
I need help please.

Answers

Answer:

x = 2.2y

Step-by-step explanation:

Given that,

1 kg = 2.2 pounds

We know that, the relation between kg and pounds is given by :

1 kg = 2.2 pounds

The variation equation can be given by :

Let x denotes kg and y denotes pounds.

So,

x = 2.2y

Hence, the variation is x = 2.2y.

Step-by-step explanation:

. To test H0: m = 105 versus H1: m ≠ 105, a simple random sample of size n = 35 is obtained. (a) Does the population have to be normally distributed to test this hypothesis by using the methods presented in this section? Why? (b) If x = 101.9 and s = 5.9, compute the test statistic. (c) Draw a t-distribution with the area that represents the P-value shaded. (d) Approximate and interpret the P-value. (e) If the researcher decides to test this hypothesis at the a = 0.01 level of significance, will the researcher reject the null hypothesis? Why?

Answers

Answer:

A.) No

B.) test statistic = - 3.108

Check explanation

Step-by-step explanation:

H0: m = 105 versus H1: m ≠ 105

Sample size, n = 35, since we have a large sample size, greater than 30.

B.)

xbar = 101.9 ; s = 5.9

Test statistic :

T = (xbar - μ) ÷ (s/√n)

T = (101.9 - 105) / (5.9/√35)

T = - 3.1 / 0.9972820

Test statistic = - 3.11

Pvalue from Tstatistic, df = 34

Pvalue = 0.003772( Pvalue calculator)

Pvalue is the probability of obtaining a value more extreme or exactly that of the test statistic.

At α = 0.01

Pvalue < α ; We fail to reject the Null

Find the distance between the pair of points (-1, 4) and (-3, 7)

Answers

Answer: d=sqrt(13)=3.605

Step-by-step explanation:

We know that the distance between the two points (x 1  ,y 1 ) and (x2,y  2 ) is

d= sqrt((x2-x1)^2 +(y2-y1)^2 )

as given

x1=-1 ,y=4 ,x2=-3,y2=7

d=sqrt((-3+1)^2+ (7-4)^2)

d=sqrt((-2)^2+(3)^2)

d=sqrt(4+9)

d=sqrt(13)=3.605

Find the perimeter of a quadrilateral with vertices at C (2, 4), D (1, 1), E (5, 0), and F (3, 4). Round your answer to the nearest hundredth when necessary.

Answers

9514 1404 393

Answer:

  12.76 units

Step-by-step explanation:

The distance formula is useful for finding the lengths of segments between given coordinates.

  d = √((x2 -x1)² +(y2 -y1)²)

Then the lengths of the line segments are ...

  CD = √((1-2)² +(1-4)²) = √10

  DE = √((5-1)² +(0-1)²) = √17

  EF = √((3-5)² +(4-0)²) = √20

  FC = √((2-3)² +(4-4)²) = 1

Then the perimeter is ...

  √10 +√17 +√20 +1 ≈ 12.7575 ≈ 12.76 units

__

In the attached, the length of "polyline" CDEF is shown as 11.76. The segment FC is shown separately.

Margaret Thatcher, Joe Lieberman, John McCain, Charles Krauthammer and other notables offered variations of The Economists cover headline: The Man Who Beat Communism.Actually, Jack F. Matlock Jr. writes in Reagan and Gorbachev, it was not so simple. . . . . In both the title of his memoir and the story it tells, he gives co-star billing to Mikhail Gorbachev.Reagan himself went even farther. Asked at a press conference in Moscow in 1988, his last year in office, about the role he played in the great drama of the late 20th century, he described himself essentially as a supporting actor. Mr. Gorbachev, he said, deserves most of the credit, as the leader of this country.Excerpt from Strobe Talbotts 2004 review of Reagan and Gorbachev: How the Cold War Ended by Jack F. Matlock Jr., the senior coordinator of policy toward the Soviet Union under President Reagana) Identify ONE specific example of how historians might argue that the end of the Cold War was attributable to Reagans policies and US pressure.b) Identify ONE specific example of how historians might argue that the end of the Cold War was attributable to Gorbachevs leadership.c) Identify ONE reason (other than partisanship), based on the events of the last decade of the Cold War, that historians might still debate the respective influences of Reagan and Gorbachev on the end of the Cold War.A) One specific example of how historians might argue that the end of the Cold War was due to Reagans policies and US pressure is the fact that during his presidency, he increased relations with the Soviet Union, while simultaneously building up the American army as both a backup plan and to prepare for a potential arms race, which put pressure on the Soviet Union. Reagan also proposed treaties between the USSR, simultaneously putting pressure on the USSR, essentially forcing them to enter into some sort of treaty or else they will enter an arms race that they likely wouldnt win.B) One specific example of how historians might argue that the end of the Cold War was a result of Gorbachevs leadership was the fact that he instituted a lot of reforms that made the country more capitalist than before, and also more democratic, which pleased the rest of the world and increased foreign relations. He attempted to ease tensions within the country and its satellite states, and started to distance the country from authoritarian rule to move towards a system more suitable for the current world. These new reforms increased foreign relations, and led to the end of the Cold War. C) One reason that historians might still debate the respective influences of Reagan and Gorbachev on the end of the Cold War is that fact that while they both contributed to it, there were a lot of other factors at play during that time period. It is often stated by historians, particularly in this case some historians at The Belfer Center at the Harvard Kennedy School in Cambridge, Massachusetts, that even if Gorbachev had not instituted the reforms that he did, the communist ideology would likely have still dissolved in the USSR. So even if Gorbachev didnt become president and put those reforms in place to decrease the influence of the communist ideology of the people, it still would have likely happened anyway. On the other hand, one could argue that Reagan didnt have much of an influence on the end of the Cold War either, as he himself even states that without Gorbachev, the end of the Cold War wouldnt have been possible. He simply made decisions that were advantageous at the time that were essentially put in place for him. Those are both sides of the argument that many historians have about the influence of each leader on the end of the Cold War. plzzzz helpIn your journal, practice a PATTR + PASAFE of "Small Change: Why the Revolution Will Not Be Tweeted" by Malcolm Gladwell from The Language of Composition.
