The y-intercept represents the initial temperature, and the rate of change gives how the temperature changes per minute.

So the correct options are A and D.

Here we have a relation that shows how the temperature changes as a function of time.

So if F(x) is the temperature and x is the time, the y-intercept is given by:

F(0)

So the y-intercept is the initial temperature, the correct option is A.

And the rate of change tells us how the temperature changes as the time passes, so we can define the rate as "the change in temperature per minute" like on option D.

The Normal model is a good approximation for the sampling distribution.

a) According to the Central Limit Theorem, the theoretical mean and standard deviation for a sample size of 20 should be 0.05 and 0.02, respectively. For a sample size of 100, the theoretical mean and standard deviation should be 0.05 and 0.01, respectively.

b) The observed mean and standard deviation for a sample size of 20 was 0.052 and 0.021, respectively. For a sample size of 100, the observed mean and standard deviation was 0.051 and 0.012, respectively. These values are fairly close to the theoretical values.

c) Looking at the histograms in Exercise 1, I would be comfortable using the Normal model as an approximation for the sampling distribution at a sample size of 100.

d) The Success/Failure Condition states that the sample size should be large enough for the sampling distribution of the sample proportions to be approximately normal. Since I chose a sample size of 100, which satisfied the condition, I can be confident that the Normal model is a good approximation for the sampling distribution.

Answer:

x = -1

y = -7

Step-by-step explanation:

y=9x+2`

-2x+7y=-47  ==> isolate y

Equation 1: 7y = 2x - 47  ==> add 2x on both sides

Equation 2: y = 9x + 2

7 * (y = 9x + 2)

Equation 3: 7y = 63x + 14

Equation 1: 7y = 2x - 47

Subtract equation 1 from equation 3:

  7y = 63x + 14

- (7y = 2x - 47)

7y-7y = 63x-2x + 14-(-47)

0 = 61x + 14 + 47

0 = 61x + 61  ==> solve for x

-61 = 61x  ==> subtract 61 on both sides to isolate x

x = -1

Using Laplace Transformation, the initial value problem y" - 2y' + y = 0 , y(0) = 1 , y'(0) = 2 is y(t) = e^t + te^t.

The differential equation is y" - 2y' + y = 0 and y(0) = 1 , y'(0) = 2

As we know that the Laplace Equation is:

[tex]L(y^n(t)) = s^nf(s) - s^{n-1}y(0) - s^{n-2}y'(0)-\dots-sy^{n-2}(0)-y^{n-1}(0)[/tex]

Now applying the Laplace Transformation in the differential equation

L(y") - 2L(y') + L(y) = 0........(1)

Now finding the value of L(y") using the equation

L(y") = s^2f(s) - s(1) - 2

L(y") = s^2f(s) - s - 2

Now finding the value of L(y') using the equation

L(y') = sf(s) - 1

Now finding the value of L(y) using the equation

L(y) = f(s)

Now putting the values in the equation 1

s^2f(s) - s - 2 - 2(sf(s) - 1) + f(s) = 0

Now solving

s^2f(s) - s - 2 - 2sf(s) + 2 + f(s) = 0

s^2f(s) - s - 2sf(s) + f(s) = 0

Taking common f(s) in term terms of f(s)

(s^2 - 2s + 1)f(s) - s = 0

Add s on both side, we get

(s^2 - 2s + 1)f(s) = s

We can write (s^2 - 2s + 1) as (s - 1)^2

(s - 1)^2f(s) = s

Divide by (s - 1)^2 on both side, we get

f(s) = s/(s - 1)^2

The value of the equation is x = -13/15 and x = 0

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

15x² + 13x = 0   be equation (1)

On simplifying the equation , we get

Subtracting 13x on both sides of the equation , we get

15x² = -13x

Divide by x on both sides of the equation , we get

15x = -13

Divide by 15 on both sides of the equation , we get

x = - ( 13/15 )

So , when x = 0

0 = 0

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

x = -13 ± √ ( 169 - 4 ( 15 ) ( 0 ) ) / 2 ( 15 )

x = -13 ± √ ( 169 - 0 ) / 30

x = ( -13 ± 13 ) / 30

The way that  the Great Awakening lead to a new American government is that; The Great Awakening helped the colonists realize they needed their own national religion.

The Great Awakening was a period in history characterized by religious revival in the US. There were five major Great Awakenings, that occurred between the beginning of 18th and the end of the 20th century. However, the last of the Great Awakenings lasted until the year 2000.

During the years of 1730s and 1740s, it was clear that the English colonies in America went through the Great Awakening which was a religious resurgence. This movement came into play at a period when there was a very huge emphasis on the idea of secular reason and as a result religious zeal had lost its freshness.

The gospel was usually preached by Christian leaders from town to town to stir up interest in Christianity while emphasizing deliverance from sin. The outcome or result was a reinvigorated commitment to religion.

The Great Awakening, in the opinion of many historians, had a profound effect on the American culture as a whole as well as on different Christian denominations.

Let length of vector is 5 then the vector in the direction of  ⟨−3,−1,5⟩ will be ⟨−15/√35,−5/√35,25/√35⟩.

What is a Vector?

Vectors, in Maths, are objects which have both, magnitude and direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction. It is also known as Euclidean vector or Geometric vector or Spatial vector or simply “vector“.

Two vectors are said to equal if their magnitude and direction are the same. It plays an important role in Mathematics, Physics as well as in Engineering. According to vector algebra, a vector can be added to another vector, head to tail. The order of addition of two vectors does not matter, because the result will be the same.

Now,

The idea is based on a concept of scaling and similarity.

Any vector that "has the same direction" as

⟨−3,−1,5⟩

has all the coordinates proportional to this given vector and, therefore, can be described by coordinates

⟨−3f,−1f,5f⟩

where f is a scaling factor.

All we need now is to find a scaling factor that leads to a vector with the length 5

The length of a vector with coordinates

⟨−3f,−1f,5f⟩

equals to√9f^2+f^2+25f^2=√35f

So, if we want the length to be equal to 5, we should choose

f=5/√35
