Answer:Thats Just Notes To Right Down.

Step-by-step explanation:

The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Using the slope-intercept form, the slope is 45 4 5 . The equation of a perpendicular line to y=4x5+7 y = 4 x 5 + 7 must have a slope that is the negative reciprocal of the original slope.

Given that in the above rectangle, m∠4 = 35°:

To understand how the above were arrived at, you must understand the properties of a rectangle.

A rectangle is a four-sided flat shape with four right angles. Its properties include:

Four sides: A rectangle has four sides, two of which are parallel and of equal length, and the other two sides are also parallel and of equal length but different from the first two.

Four right angles: All four angles of a rectangle are right angles (90 degrees).

Opposite sides are parallel: The two pairs of opposite sides are parallel to each other.

Diagonals are equal: The diagonals of a rectangle bisect each other, which means they cut each other into two equal parts.

Equal opposite sides: The opposite sides of a rectangle are equal in length.

Equal adjacent sides: The adjacent sides of a rectangle are also equal in length.

Symmetry: A rectangle has two lines of symmetry, which means it can be divided into two equal parts by a line that passes through its center.

Area: The area of a rectangle is calculated by multiplying its length and width together.

Perimeter: The perimeter of a rectangle is calculated by adding the length of all four sides together.

So,

Note that ∠ABC = ∠BCD = ∠CDA = ∠DAC = 90°

This means that ∠BCA = 4 + 3 = 90°

Since m∠4 = 35°

m∠3 = 90 - 35°; therefore

m∠3 = 55°

This logic holds true for ∠ABC, and ∠6 where ∠6 =35° - Properties of a diagonal of a rectangle.

Note that m∠4 = m∠1 - Alternate angles thus,

∠1 = 35°

Since ∠4 = ∠6 = 35°

∠5 = 180 - (35 + 35)  -  Sum of Angles in a Triangle.

∠5 = 110°

There are other was to find ∠8 but the easiest is to use sum of angles on a straight line. Since ∠5 and ∠8 are supplementary,

m∠8 = 180 - 110 = 70°

Thus, if ∠8 = 70° and ∠3 = 55; then

m∠7 = 180 - (70 + 55) - Sum of Angles in a Triangle
m∠7 = 55°

Thus, in summary,

The solution for A'0 is as follows:

A'0 = (βR^(-1/γ) / (1 - R^(-1/γ)))^(1/γ)

We start with the equation (A0 - A0')^(-γ) = βR(RA0')^(-γ). To solve for A'0, we isolate it on one side of the equation.

First, we raise both sides to the power of -1/γ, which gives us (A0 - A0') = (βR(RA0'))^(1/γ).

Next, we rearrange the equation to isolate A'0 by subtracting A0 from both sides, resulting in -A0' = (βR(RA0'))^(1/γ) - A0.

Finally, we multiply both sides by -1, giving us A'0 = -((βR(RA0'))^(1/γ) - A0).

Simplifying further, we get A'0 = (βR^(-1/γ) / (1 - R^(-1/γ)))^(1/γ).

\(\sum\limits_{i=1}^{n} i^2 \ is \ equal \ to \ a = \dfrac{n \cdot (n + 1) \cdot (2 \cdot n + 1)}{6}\)

Step-by-step explanation:

1) The sum of a series of the cubes of numbers 'i' is given as follows;

Sₙ = n/2 × (1st term + Last term)

∴ Sₙ = n/2 × (1 + n) = n·(n + 1)/2

It can be shown that the sum of a series of the cubes of numbers 'i²' is given as follows;

Sₙ = (n·(n + 1)·(2·n + 1))/6

It can be also be shown that the sum of a series of the cubes of numbers 'i³' is given as follows;

Sₙ = (n·(n + 1)/2)²

Therefore, we have;

\(\sum\limits_{i=1}^{n} c \cdot a_i= c \cdot \sum\limits_{i=1}^{n} a_i = c\)

\(\sum\limits_{i=1}^{n} i = \dfrac{n \cdot (n + 1)}{2} = b\)

\(\sum\limits_{i=1}^{n} c = c \cdot n = d\)

\(\sum\limits_{i=1}^{n} i^3 = \left [ \dfrac{n \cdot (n + 1)}{2} \right]^2 = e\)

\(\sum\limits_{i=1}^{n} i^2 = \dfrac{n \cdot (n + 1) \cdot (2 \cdot n + 1)}{6} = a\).

In isocseles triangle, base angles are equal :

base angles are angle N and angle P:

angle N=angle P

3x+17=4x+2

4x-3x=17-2

x=15

For angle N:

subtitute x in angle N

=3(15)+17

=45+17

=62

For angle P:

subtitute x in angle P:

=4(15)+2

=60+2

For angle O:

sum of all angles in a triangle is 180.

angle N +angle P+angle O=180

62+62+angle O=180

angle O=180-62-62

Answer:

For a normal distribution, the probability of a value being between a positive z-value and its population mean is indeed the same as that of a value being between a negative z-value and its population mean.

This is due to the symmetric nature of the normal distribution curve, where probabilities are mirrored around the mean.

The normal distribution is characterized by its bell-shaped curve, which is symmetric around the mean. The mean is also the midpoint of the curve, and the curve approaches but never touches the horizontal axis. The standard deviation of the distribution controls the spread of the curve.

In a normal distribution, the probability of a value being between a positive z-value and its population mean is indeed the same as that of a value being between a negative z-value and its population mean.

This is due to the symmetric nature of the normal distribution curve, where probabilities are mirrored around the mean.

This means that if we have a normal distribution with a mean of μ and a standard deviation of σ, the probability of a value falling between μ+zσ and μ is the same as the probability of a value falling between μ-zσ and μ.

This property of the normal distribution makes it easy to compute probabilities for any range of values, by transforming them into standard units using the z-score formula.

Commonly, research begins with a straightforward random sample. This enables them to statistically analyze a sample of people drawn from a bigger population or group in order to simulate the response of the complete group.

Why does a field (a list of every person in the population) need to be included in simple random sampling?) :-

   - Simple random sample is the term used to describe a smaller portion    of a bigger population. Each person in this area has an equal probability of being selected. For this reason, a straightforward random sample is intended to be impartial in its portrayal of the wider group. This approach typically has an error margin, which is denoted by a plus or minus variant. An example of a sampling error is this.

why does the requirement of a field make collecting a simple random sample difficult :-

    - Only when a complete list of the entire population to be researched is available can a simple random sampling yield an accurate statistical measure of a big population. Consider a list of university students or a group of workers at a particular business.

The availability of these lists is the issue. Accessing the entire list can therefore be difficult. It's possible that some colleges or universities won't want to give researchers an exhaustive list of their faculty or students. Similar to this, some businesses might not be able or willing to provide information about particular employee groups due to privacy policies.

Typically, research starts with a simple random sample. This gives them the ability to statistically assess a group or population sample taken from a larger one in order to imitate the response of the entire group.

Why does simple random sampling require a field (a list of every person in the population)?

A smaller subset of a larger population is referred to as a simple random sample. Everyone in this area has an equal chance of being chosen. Because of this, a simple random sample is meant to represent the larger group objectively. An plus or minus variant is used to indicate the approach's typical error margin. This is an illustration of a sampling inaccuracy.

Why is it difficult to gather a simple random sample because of a field's requirements:-

- A simple random sample cannot produce an appropriate statistical measure of a large population unless the entire population to be studied is accessible. Think of a list of college students or a team of employees at a specific company.

The problem is the accessibility of these lists. It may be challenging to access the complete list as a result. Some schools and universities might not wish to provide a complete list of their faculty or students to researchers. Similar to this, due to privacy policies, some businesses might not be able or willing to provide information about specific employee groups.
