How do you find the z-score for a sample mean on the distribution of means?

Answers

The formula z = (x-μ)/σ allows us to determine the z-score for a sample mean on the distribution of means.

What is a z-score?

A Z-score is a metric that quantifies how closely a value relates to the mean of a set of values.

Standard deviations from the mean are used to measure Z-score.

A Z-score of zero means the data point's score is the same as the mean score.

Z-scores are calculated using the formula z = (x-μ)/σ, where x represents the raw score, the population mean, and the population standard deviation.

The z-score is simply the raw scoreless the population means, divided by the population standard deviation, as the calculation demonstrates.

Therefore, the formula z = (x-μ)/σ allows us to determine the z-score for a sample mean on the distribution of means.

Answers

Answer:

Step-by-step explanation:

Simplifying the expression (m^4n)^3 can be done by using the laws of exponents. The first law states that when two terms with identical bases are being multiplied, you add their exponents together. In this case, m is the base and 4n is its exponent; therefore, when we multiply them together three times (or raise to the third power), then our result should be m raised to a power of 12n.

The Cartesian coordinates of a point in three dimensions are the triple (x, y, z). The three numbers or coordinates give the signed distance from the origin along the x, y, and z axes respectively.

Solution:

Given, x1 = -3     ,  x2 = 2

           y1 = 5      ,  y2 = -4

           z1 = -7     ,  z2 = 6

The formula for finding the distance between two points on 3D graph is given below

Distance =√((x2-x1)²+(y2-y1)²+(z2-z1)²)

⇒Distance =√{(2-(-3))²+(-4-5)²+(6-(-7))²}

⇒Distance =√{(2+3)²+(-9)²+(6+7)²}

⇒Distance =√{5²+81+13²}

How many odd numbers of 3 digits are there which have all 3 digits distinct?

Answers

There are 60, odd numbers of 3 digits are there which have all 3 digits distinct with each of the digits odd.

we know that,

Now there are 5 odd numbers from 0 to 9. Those are 1,3,5,7 and 9. Now we need to fill these into three places and make sure that the numbers do not repeat.

Let us take the example of the number 135.

1st digit  2nd digit    3 digit

1               3          5

Now 135 is the first number which satisfies all the conditions.

Similarly, we can find many numbers but this would take a lot of time.

Let us generalize this.

Now we have 5 options to be put in the 1st digit place. So

1st place = 5 options.

Now since the numbers do not have to repeat the number of options we need to put in the second place will reduce to (5-1) that is 4. Thus, 2nd place = 4 options.

Now in the third place too the numbers should not repeat. Thus our options further reduce to (5-3) that is 3 options. Thus,

3rd place = 3 options.

Now, to find all the arrangements, we multiply the number of options in all places.

Thus the total number of numbers is equal to 5×4×3=60

Thus , there are 60, odd numbers of 3 digits are there which have all 3 digits distinct with each of the digits odd.

Are all equilateral triangles congruent Yes No?

Answers

All equilateral triangles are NOT congruent.

Only those equilateral triangles whose sides have the same length will be congruent.

Those whose sides have different lengths will not be congruent.

By the criteria of congruence:Side Angle Side: Two triangles are congruent if two sides of one triangle have the same measure as the two sides of the other, the angle being equilateral if they have the same (60º)Side Side Side: Two triangles are congruent if all three sides of one have the same length as the other.Angle Side Angle: Two triangles are congruent if two of their angles and the side between the two angles are equal in the other triangle.
Answer: No

Reasoning:

Equilateral triangles can have differing side lengths, but they all have congruent angles (60°). Therefore, all equilateral triangles are similar, but not always congruent.

Let’s see why the angles always measure 60°:

Given an equilateral triangle with three sides: a, a, a. Find the angle measure of the interior angles, denoted as x.

We know by the Triangle Sum Theorem, that all interior angles of a triangle sum up to 180.° Because the triangle is an equilateral triangle, all angle measures of x will be equal, so we can create an equation:

x+x+x=180

3x=180

x=180/3

x=60°

A rectangular frame is placed around a water color painting. the width of the frame is consistent around the painting. the dimensions of the painting are 24 inches by 18 inches. what is the width of the frame if the area of the frame is 400 square inches?

Answers

If the frame has a 400 square inch surface area, its breadth is 5 inches.

Let's call the width of the frame w.

The total width of the painting and the frame is 24 inches + 2w inches since there is a frame of width w on both sides of the painting.

Similarly, the total height of the painting and the frame is 18 inches + 2w inches, since there is a frame of width w on both the top and bottom of the painting.

The area of the frame is the difference between the area of the rectangular frame and the area of the painting. The area of the rectangular frame is (24 inches + 2w inches) * (18 inches + 2w inches) = 432 inches + 72w inches + 36w inches + 4w^2 inches. The area of the painting is 24 inches * 18 inches = 432 inches.

Therefore, the area of the frame is 432 inches + 72w inches + 36w inches + 4w^2 inches - 432 inches

= 72w inches + 36w inches + [tex]4w^2[/tex] inches = 400 inches.

Combining like terms, we get [tex]4w^2[/tex] inches + 108w inches = 400 inches.

Dividing both sides by 4, we get [tex]4w^2[/tex] inches + 27w inches = 100 inches.

We can use the quadratic formula to solve this equation in the quadratic form:

w = [tex]\frac{(-b +/- sqrt(b^2 - 4ac))}{2a}[/tex]

= [tex]\frac{(-27 +/- sqrt(27^2 - 4 * 1 * 100))}{2*1} \\[/tex]

= [tex]\frac{(-27 +/- sqrt(729 - 400))}{2}[/tex]

= [tex]\frac{(-27 +/- sqrt(329)) }{2}[/tex]

= [tex]\frac{(-27 +/- sqrt(289))}{2}[/tex]

The solutions are w =[tex]\frac{ (-27 + 17)}{2}[/tex]  = -5 inches and w = [tex]\frac{(-27 - 17)}{2}[/tex] = -22 inches.

Since the width of the frame must be positive, the correct solution is w = -5 inches. The frame is five inches wide.

If f(x) has a y-intercept at 5 and x-intercepts at 2 and −4, and if g(x) = −2f(x), what are the intercepts of g(x)?

Answers

Answer:

y-intercept: -10x-intercepts: 2 and -4

Step-by-step explanation:

You want to know the intercepts of g(x) = -2f(x), where the intercepts of f(x) are (0, 5), (2, 0) and (-4, 0).

Vertical scaling

The scale factor of -2 applied to f(x) multiplies each of the y-coordinates by -2.

  (x, y) ⇒ (x, -2y)

  (0, 5) ⇒ (0, -10) . . . . y-intercept

  (2, 0) ⇒ (2, 0) . . . . . x-intercept

  (-4, 0) ⇒ (-4, 0) . . . . x-intercept

The intercepts of g(x) are (0, -10), (2, 0) and (-4, 0).

The intercepts of g(x) = -2f(x) are (0, -10), (2, 0), and (-4, 0).

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

f(x) has a y-intercept at 5 and x-intercepts at 2 and −4.

This means,

(0, 5), (2, 0), and (-4, 0)

Now,

g(x) = -2f(x).

This means,

Vertical scaling.

Multiply -2 with the y-coordinate.

(0, 5) = (0, -10)

(2, 0) = (2, 0)

(-4, 0) = (-4, 0)

add 15 to both sides -> 15=3x

divide both sides by 3, 5=x

x intercept is (5, 0)

to test if (2, -9) solution, lets plug in 2 for x and see if we get an answer of -9

so y=3(2)-15

y=6-15

y=-9

so yes, (2,-9) is a real solution

Answer:

[tex]\displaystyle{\theta=\dfrac{5\pi}{4}\, , \, \dfrac{9\pi}{4}}[/tex]

Step-by-step explanation:

Given the equation [tex]\displaystyle{2\cos \theta = 2\sin \theta}[/tex]. We have to divide both sides by 2 which gives us [tex]\displaystyle{\cos \theta = \sin \theta}[/tex]. Then divide both sides by [tex]\displaystyle \cos \theta[/tex] which gives us [tex]\displaystyle{1=\dfrac{\sin \theta}{\cos \theta}}[/tex].

We know that:

[tex]\displaystyle{\dfrac{\sin \theta}{\cos \theta} = \tan \theta}[/tex]

So we can rewrite the equation as [tex]\displaystyle{1=\tan \theta}[/tex].

We know that [tex]\displaystyle{\tan \theta = 1}[/tex] when [tex]\displaystyle{\theta = \dfrac{\pi}{4}+\pi k}[/tex] for [tex]\displaystyle{k \in I}[/tex] (k is any integer). However, the equation is given with the interval [tex]\displaystyle{\pi \leq \theta \leq 3\pi}[/tex]. Therefore, we have to substitute k-values that satisfy the interval.

It appears that only k = 1, 2 which gives us [tex]\displaystyle{\theta_1 = \dfrac{\pi}{4}+\pi}[/tex] and [tex]\displaystyle{\theta_2 = \dfrac{\pi}{4}+2\pi}[/tex]can be used since both satisfies both values and interval.

Simplifying both solutions:

[tex]\displaystyle{\theta_1 = \dfrac{\pi}{4}+\dfrac{4\pi}{4} \, , \, \theta_2=\dfrac{\pi}{4}+\dfrac{8\pi}{4}}\\\\\displaystyle{\theta=\dfrac{5\pi}{4}\, , \, \dfrac{9\pi}{4}}[/tex]

Answers

The mean and standard deviation of the sampling distribution of the sample proportion are: (d) 0.55, 0.0497.

What is a sample proportion?

In Mathematics and Statistics, a sample proportion can be defined as the proportion of individuals in a sample that have a specified characteristic or trait.

The mean of the sampling distribution of the sample proportion is equal to 0.55. Mathematically, the standard deviation of the sampling distribution of the sample proportion can be calculated by using this formula:

σp = √(p(1 - p)/n)

Substituting the given parameters into the standard deviation formula, we have;

Standard deviation, σp = √(0.55(1 - 0.55)/100)

Standard deviation, σp = √(0.55(0.45)/100)

Standard deviation, σp = 0.002475

Standard deviation, σp = 0.0497

How do you solve for x and y in two equations?

Answers

We can solve for x and y in two equations by using the Elimination method for the simultaneous linear equations.

The Elimination approach results in the reduction of one problem to a single-variable equation when two simultaneous linear equations are solved. Following this, the answer is the same as when one line was vertical or parallel. The Gaussian elimination method is the name given to this approach.

We can understand the above method through an example:

Equation 1:     4x + 6y = 8

Equation 2:     3x + 4y = 5

Step 1: In order to ensure that the two equations have the same leading coefficient, multiply each equation by a reasonable value. Equation 1 may be easily solved by multiplying it by 3, the x coefficient from Equation 2, and Equation 2 by 4, the x coefficient from Equation 1.

Therefore the equations become,

12x + 18y = 24

12x + 16y = 10

Step 2: Subtract equation 2 from equation 1

We get 2y = 14

From the above equation, we get the value of y as 7

Step 3: We will substitute the value of y in one of the initial equations

Substituting the value of y in equation (1) 4x + 6y = 8

4x + 6(7) = 8

4x + 42 = 8

4x = 34

x = [tex]\frac{34}{4}[/tex]

x = [tex]\frac{17}{2}[/tex]

They write so that their work can be portrayed on the theatrical stage and can be seen by an audience. For many writers, having their work shown on the Broadway or London stage is a triumph. However, success on the stage can be fleeting for some playwrights. On Broadway, plays and musicals sometimes only last for a few weeks. Harsh critics can damage the play's reputation and make it difficult for the play to find an audience. But, for the lucky few playwrights, their work can last for years. Neil Simon is one of the fortunate playwrights to achieve major success on Broadway. In 1961, Come Blow Your Horn was Simon's first play to open on Broadway. It ran for 678 performances at the Brooks Atkinson Theatre. Following this achievement, Simon had four shows running simultaneously in 1966. The shows were Sweet Charity, The Odd Couple, The Star-Spangled Girl, and Barefoot in the Park. Simon's writing for Lost in Yonkers even gave him the Pulitzer Prize for Drama in 1991. The play focused on the dynamics of a family living in Yonkers, New York. It also showed how the family members negatively affected each other. In addition, to Simon's success on Broadway, he also was a notable screenwriter. He adapted many of his plays into film. Simon's The Odd Couple was one of his winning adaptations. The storyline has become a part of popular culture. It was a hit on Broadway because the story focused on two mismatched roommates, who live with each other after their divorces. They were originally played by Art Carney and Walter Matthau. Following that, Simon wrote the script so that the play could be translated onto the big screen. Because of its popularity, the play's concept also became a television series, which lasted five years. The show aired on ABC with minor changes from the play. The television scripts were not written by Simon himself. There are still few revivals of The Odd Couple on the stage and in television.Which detail from the passage supports the claim that Neil Simon achieved success in different media? A.
