Was this an actual question?

Step-by-step explanation:

Which values are part of the solution set based on the result of the inequality?

-4x + 24 < -2x + 2

add 2x to both sides:

-4x + 24 + 2x < -2x + 2 + 2x

-2x + 24 < 2

subtract 24 from both sides:

-2x + 24 - 24 < 2 - 24

-2x  < -22

divide both sides by -2: [remember to flip the sign direction because you are dividing by a negative number]

-2x/-2  > -22/-2

x  > 11

Step-by-step explanation:

The total number of small boxes is 1.72 and the large boxes is 5.1.

Given;

To build a house, a contractor has to purchase nails. Both small and large boxes of nails are provided. There are 100 nails in each small box and 450 in each large box. The contractor purchased 3 more tiny boxes—totaling 2500 nails—than large boxes.

To calculate the proportion of small and large boxes that were bought,

Let's assume the small boxes as 's' and the big boxes as '3s'.

∴ s(100) + 3s(450) = 2500

   100s + 1350s = 2500

   1450s = 2500

   s = 2500/1450

   s = 1.72

∴ 3s = 1.72 * 3

       = 5.1

Hence, the total number of small boxes is 1.72 and the number of large boxes is 5.1.

The number of small boxes purchased is 7 and the number of large boxes purchased is 4 by the contractor.

Let the number of large boxes purchased = x

then the number of small boxes purchased = x + 3

It is also given that,

small box contains = 100 nails

large box contains = 450 nails

According to the question:

450x + 100(x + 3) = 2500

450x + 100x + 300 = 2500

550x = 2500 - 300 = 2200

x = 2200/550

x = 4

and x + 3 = 4 + 3 = 7.

Thus, Let the number of small boxes purchased = 4 and the number of small boxes purchased = 7.

According one-way ANOVA, the test is false.

In the given question,

When comparing three or more populations means within a set of quantitative data that is categorized according to one​ factor/treatment, a​ one-way ANOVA is appropriate. It is also appropriate in this​ situation, however, to compare two means at a time using multiple independent two sample​ t-tests. We have to check whether this is true or​ false.

We firstly learn about one-way ANOVA

"One-Way ANOVA, also known as "analysis of variance," examines the means of two or more independent groups to see if there is statistical support for the notion that the related population means are statistically substantially different."

According to the given method it is inappropriate to compare two means at a time using multiple independent two sample​ t-tests. It will create multiple testing problem and error.

So using one way ANOVA test when comparing three or more populations means within a set of quantitative data that is categorized according to one​ factor/treatment and compare two means at a time using multiple independent two sample​ t-tests is false.

The values of the elements of the matrix will ψ(t)⟩=e−iE1t/ℏ|2⟩

Let's say the block matrix is used to represent the 2n by 2n matrix A.

Displaystyle A="begin" "bmatrix" "a&b" "c&d" "end"

where n-by-n matrices a, b, c, and d. The requirement that b and c be symmetric and that a + dT = 0 are similar to the requirement that A be Hamiltonian. The fact that A is of the form A = JS with S symmetric is another equivalent requirement.

Two Hamiltonian matrices can be added together (as can any linear combination), and their commutator is also Hamiltonian. The space of all Hamiltonian matrices is hence a Lie algebra, indicated by the symbol sp (2n). Sp(2n) has a dimension of 2n2 + n.

H^=E0(|1⟩⟨1|+|3⟩⟨3|)+E1|2⟩⟨2|+A(|1⟩⟨3|+|3⟩⟨1|)H^=E0(|1⟩⟨1|+|3⟩⟨3|)+E1|2⟩⟨2|+A(|1⟩⟨3|+|3⟩⟨1|)

It is then straightforward to see that :

• |2⟩|2⟩ is an eigen state with eigen value E1E1 as you have already noticed. Hence if the initial state is |2⟩|2⟩ then

|ψ(t)⟩=e−iE1t/ℏ|2⟩

• (|1⟩+|3⟩)(|1⟩+|3⟩) and (|1⟩−|3⟩)(|1⟩−|3⟩) are eigen states with respective eigen values of E0+AE0+A and E0−AE0−A. Hence if the initial state is |3⟩=12[(|1⟩+|3⟩)−(|1⟩−|3⟩)]|3⟩=12[(|1⟩+|3⟩)−(|1⟩−|3⟩)], then

|ψ(t)⟩=12[e−i(E0+A)t/ℏ(|1⟩+|3⟩)−e−i(E0−A)t/ℏ(|1⟩−|3⟩)]

The circumference and the area of the circle in terms of "π" are 24π and 144π.

We are given a circle. The coordinates of the center of the circle are (12, -1). The circle passes through a point. The coordinates of the passing point are (0, -1). We need to find the circumference and area of the circle.

Let the radius, circumference, and area of the circle be denoted by the variables "r", "C", and "A", respectively. The radius is the distance between the center of the circle and a point on its boundary. We will use the distance formula.

r = √[(12 - 0)² + (-1 - (-1))²]

r = √[144 + 0]

r = 12

The radius of the given circle is 12 units.

The circumference of the circle is calculated below.

Using the equation of line, the equation parallel to y=5 and passing through (3,-5) is y+5=0.

In the given question,

We have to find an equation parallel to y=5 and passing through (3,-5).

The equation parallel to y=5.

Point is (3,-5).

We firstly find the slope of y=5

Expressing the equation in the general form

y=0×x+5

On comparing to the y=mx+c, we get slope(m) = 0.

The given point is (3,-5) in which [tex]x_{1}[/tex]=3 and [tex]y_{1}[/tex]= -5

Now finding the equation.

So the Equation of line is

y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])

y-(-5)=0(x-3)

Simplifying

y+5=0

The point on the y-axis is (0,1) such that the distance is minimum.

Let the coordinate of the point W be (0,a)

We know that the distance from any point on the coordinate place is calculated using the distance formula.

Now let us calculate the distance of VW = √[(2-0)²+(3-a)²]

Distance XW = √[(-2-0)²+(-1-a)²]

Now the sum of the distances is given by:

VW + XW

=√[(-2-0)²+(-1-a)²] + √[(2-0)²+(3-a)²]

This can be written in the form of a function in a such that:

f(a) = √a²+2a+5 + √a²-6a+25

Now we will differentiate with respect to a to get the required first degree

f'(a) = [tex]\frac{a+1}{\sqrt{a^2+3a+5}} + \frac{a-3}{\sqrt{a^2-6a+25}}[/tex]

Now at f'(a)=0

we get a=1.

The ordered pair (x,y) obtained from the linear equations is: (-2,-12)

What is Linear Equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

Definition of a Linear Equation: Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason. A linear equation is expressed using the linear equation formula. There are several ways to accomplish this. A linear equation, for instance, can be written in standard form, slope-intercept form, or point-slope form. To discover how a linear equation is stated in its standard form, let's take an example.

The equation is given:

8x-3y=20

5x-y=2

Using the substitution method for solving the linear equations:

From the equation:

5x-y=2;

we can transform this equation as:

⇒-y = 2-5x;

⇒y = 5x-2;

Now substituting the value of y in the other equation: we get;

⇒8x-3(5x-2)=20

⇒8x -15x+6 = 20;

⇒-7x=14;

x = -2;

Now putting the value of x in the equation to get the value of y;

So,

y = 5(-2) -2;

y = -12;

Hence the value of x and y are -2 and -12 respectively;

The 95% confidence interval estimate of the population mean is between $50,555.51 and $51.444.49.

Confidence interval is defined as the range of values where a parameter might fall at a given confidence level. It can be calculated using the formula below.

CI = μ ± z x (SD / √n)

where CI = confidence interval

μ = sample mean

z = found by using a z-score table

SD = sample standard deviation

n = sample size

At 95% confidence level, the area in each tail of the standard normal curve is 2.5, and the cumulative area up to the second tail is 97.5.

(100 - 95) / 2 = 2.5

100 - 2.5 = 97.5

Find 0.975 in the z-table to get the value of z.

At p = 0.95, z = 1.96
