Number of side of polygon will be 18.

What is polygon?

A plane figure may be a figure that's delineated by a finite variety of line segments connected to create a closed plane figure chain is called polygon.

Main body:

Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. Let the number of sides be n.

n = 18, an octadecagon.

Measure of Each Interior Angle

If you imagine a regular octadecagon (or any polygon), you will notice that the exterior angle is the supplement of the interior angle.

20° = 180° - I, where I is the interior angle.

[20°] + I = [180° -I] + I

[20° + I] - 20° = [180°] - 20°

I = 160 degrees

Sum of the Interior Angles:

Sum of interior angles is 180° (n - 2). The way I remember this equation is by remembering that the equation contains 180° and the number of sides, and that the sum of interior angles of a triangle is 180°.

=180° (18 - 2)

=180° (16)

=(200 - 20)° (16)

=(3200 - 320)°

=2880°

Sum of the Exterior and Interior angles

360° + 2880° = 3240°

The equation for profit relating to N(number of book ) is P = 15.21N - 650 .

In the question ,

it is given that

the small publishing company is releasing a "new book" ,

the cost(c) for the production of books is = 17.59*N + 650 ,

where N denotes the number of books .

total Revenue earned (in dollars) from selling the books is given by the function R = 32.80*N .

So , the Profit(P) = Revenue - Cost

Substituting the value of Revenue and Cost ,

we get ,

Profit = 32.80*N - (17.59*N + 650)

P = 32.80N - 17.59N - 650

P = 15.21N - 650

Therefore , The equation for profit relating to N(number of book ) is P = 15.21N - 650   .

The given question is incomplete , the complete question is

A small publishing company is releasing a new book. The production costs will include a one-time fixed cost for editing and an additional cost for each book printed.

If a and b are disjoint, then the value = 1.

If two events are mutually exclusive then the probability of them happening or occurring simultaneously is by definition zero. However, the described setting is impossible.

Let’s review the situation. At a given point in time there are four possible states of the world:

We know that

Pr(S4) = 0,

since A and B are mutually exclusive. We also know that the probability of A happening is 0.2, which is in states S2 and S4, so

Pr(S2) + Pr(S4) = 0.2.

Moreover, the probability of B happening is 0.8, which is in states S3 and S4, so

Pr(S3) + Pr( S4) = 0.8.

Since PR(S4) = 0, it follows that

P(S2)= 0.2

and

Pr(S3) = 0.8.

However, that means that the probabilities of all possible states do not sum to 1 as they should for a probability distribution, since Pr(S2) + Pr(S3) is already 1. So the problem definition describes an impossible situation.

Hence the answer is if a and b are disjoint, then the value = 1.

The population variance is a measure of the spread of values from their mean.

We need to define the population variance. The population variance is the variance of the population. Population variance describes how data points are distributed. It is the square of the average distance between each data point in the population and the mean.

In probability theory and statistics, variance is defined as the expectation of a random variable's squared deviation from its population mean or sample mean.

An average is a single number that represents a set of numbers, generally the sum of the numbers divided by the number of numbers in the set.

A set of data is given: 3, 7, 11, 11, 16 Jesse calculated a measure of central tendency and got 9. 6.

Jesse has calculated the Mean of the given set of data. The centre or middle of a set of data values is represented by a measure of central tendency. Mean, median, and mode are the most often used measures of central tendency.

The most common and well-known index of central tendency is the mean (or average). Although it can be used with both discrete and continuous data, continuous data is the most common type utilized with it. The mean is determined by dividing the total number of values in the data set by the number of values in the data set.

Formula for calculating mean is -  Sum of the observations/Total number of observations.

So here in the question, the sum of the observations is 48 which is calculated by adding all the values of data i.e 3+7+11+11+16 = 48 and the total number of observations are 5.

Given: 6x²+64x-222 = -8x

To change the given equation to the form (x+a)² = b, the steps below will be all intermediate steps involved:

6x²+64x-222 = -8x

2(3x²+32x-111) = 2(-4x)

Number which produces an irrational number when multiplied by 1/2 is 2/3.

Any real number that cannot be written as the quotient of two integers, p/q, where p and q are both integers, is referred to as an irrational number. For instance, the square root of 2 cannot be expressed as an integer or a fraction. Additionally, if the value of the square root of 7 yields a value after the decimal point that neither terminates nor repeats, it will be an irrational number. The number 7 is an irrational number because its value, 2.64575131106, is non-terminating and non-repeating.

What is a function?
A function is a special kind of relation where each input has exactly one output. In other words, for each input value, the function returns exactly one value. A relation instead of a function is depicted in the above graph as one is mapped to intermediate values. However, if someone were instead mapped to the a single value, the relationship described above would change into a function. Furthermore, output values could match input values exactly. The function machine receives the x-values as input. After finishing its operations, the function machine outputs the y-values. Any function may be the one within.

The given function f(x) = x²-3x+1

So we can replace x ---→ p²

The slope of the line that passes through (3,4) and (2,-1) is 5/1 as a fraction

From the question, the points are given as

(3,4) and (2,-1)

Rewrite the above points properly

So, we have the following ordered pairs

(x, y) = (3,4) and (2,-1)

The slope of the line is then calculated using the following slope equation

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (3,4) and (2,-1)

Substitute the known values in the above equation

So, we have the following equation

Slope = (-1 - 4)/(2 - 3)

Evaluate the difference in the above equation

So, we have the following representation

Slope = -5/-1

Lastly, we evaluate the quotient

So, we have

Slope = 5

The solution is to be in fraction form

So, we have

Slope = 5/1

Hence, the slope of the line is 5/1
