the equation of the circle is ⇒ x² + y² = 8 ,

we know that the general equation of the circle is given as x² + y² = b² ;

and "b" is the radius of circle ,

On comparing both the equations ,

we get ,

b² = 8

Simplifying the above equation further ,

we get ,

b = √8 = √2 × 2 × 2

the radius "b" is

b = 2√2 units .

Therefore , the length of the radius of the circle is 2√2 units .

Raw score can be computed by using arithmetical operations such as addition, subtraction, multiplication, and division.

This can be done by hand or by using a calculator or a computer program. Additionally, statistical methods such as mean, median, mode, and standard deviation can be used to compute raw data. Raw data can also be influenced in many ways.

For example, data can be organized, filtered, and sorted into categories or hierarchies. Data can also be visualized in graphs, charts, and diagrams to make patterns and trends feasible to understand. Statistical methods such as correlation and regression can also be used to analyze and interpret raw data. Additionally, data can be combined with other data sets to create new insights and relationships.

The relationship between the variable is the direction, strength, and linearity .

Scatterplots can be used when one continuous variable is under the control of the experimenter and the other is dependent on it, or when both continuous variables are independent. When one parameter is systematically increased and/or decreased by the other, it is called the control parameter or independent variable and is usually plotted along the horizontal axis. Measured or dependent variables are usually plotted along the vertical axis. In the absence of a dependent variable, any type of variable can be plotted on any axis and the scatter plot he only shows the degree of correlation (not causality) between the two variables.

Scatterplots can suggest different types of correlations between variables with specific confidence intervals. If the dot pattern slopes downwards from the lower left to the upper right, this indicates a positive correlation between the investigated variables. If the dot pattern slopes from top left to bottom right, it indicates a negative correlation. You can draw a line of best fit (also called a "trend line") to explore the relationship between variables. The formula for correlation between variables can be determined by established best-fit methods. For linear correlation, the optimal procedure is called linear regression, which guarantees a correct solution in finite time. There is no one-size-fits-all procedure that guarantees the correct resolution in any relationship. Scatterplots are also very useful for seeing how two comparable data sets match up to show non-linear relationships between variables.

Desired Weight:

A standardized table of desirable (or ideal) weight for adult height is based on life expectancy. Both malnutrition and obesity are associated with an increased risk of early death. A desirable weight corresponds to a body mass index (ratio of weight in kg/height in m2) between 20 and 25. Ideal weight charts based on actuarial data were first published in 1942 by the Metropolitan Life Assurance Company of New York and were replaced in 1959 by charts of average and desirable weights.

The strategy to catch the spider is elaborated out here.

The best strategy for catching the spider after infinitely many steps is to start at one point in the grid and then move in a clockwise spiral, expanding your search area every time you move. As you move, you can use a combination of visual and physical cues, such as vibrations and sound, to detect the spider's presence. This method will ensure that the spider will eventually be caught in a finite amount of time. Additionally, if the spider changes directions, your search will be able to adjust to that change, as you will be able to detect it in the spiral pattern.

The vertex of the equation is (3, -290). Then the solutions of the equation will be 99.67 and -93.67.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The equation is given below.

y = 3x² - 18x - 263

Convert the equation into vertex form, then we have

y = 3x² - 18x - 263

y = (√3x)² - 2 · √3x · 3√3 + 27 - 27 - 263

y = 3(x - 3)² - 290

Then the solution of the equation will be given as,

3(x - 3)² - 290 = 0

3(x - 3)² = 290

x - 3 = ± 96.67

x = 3 ± 96.67

x = 3 + 96.67, 3 - 96.67

x = 99.67, -93.67

The vertex of the equation is (3, -290). Then the solutions of the equation will be 99.67 and -93.67.

When a six-sided die and an eight-sided are rolled then the probability that exactly one 6 is rolled is 1/4.

Given, a six-sided die (with numbers 1 through 6) and an eight-sided die (with numbers 1 through 8) are rolled.

we have to find the probability that exactly one 6 is rolled.

First we have to check the total number of outcomes on rolling both the dices.

Now, the total number of outcomes be, 48

As, we the favorable outcomes be, the outcome with exactly one 6 on the dices.

Favorable Outcomes = { (1,6) , (2,6) , (3,6) , (4,6) , (5,6) , (6,1) , (6,2) , (6,3) , (6,4) , (6,5) , (6,7) , (6,8)}

The total number of favorable outcomes be, 12

So, the probability that exactly one 6 is rolled is

P(E) = Number of favorable outcomes / Total number of outcomes

P(E) = 12/48

P(E) = 1/4

There are 26¹⁰ - 4 × (25)¹⁰ + 2 × (24)¹⁰ + 22¹⁰ exponential generating Function to make an arrangement  of Pennies, nickels, dimes and quarters with at least one penny and an odd number of quarters.

Exponential generating Function:

An exponential generator provides a way to encode a sequence as the coefficients of a power series. This encoding helps in many ways.

Therefore, According to the Question:

The exponential generating function is,

G(x) = (x¹/1! + x²/2! + ...)(x¹/1! + x³/3! + x⁵/5! +...)(x°/0! + x¹/1! + x²/2! + ...)²

where the first factor describes the pennies, the second describes the quarters, and the last describes nickels and dimes.

We want the coefficient of  Xˣ /r!.

Using exponential identities we get,

G(x) = [tex]e^{x} - 1 (\frac{e^{x} - e^{-x} }{2} ) (e^{x} )^2[/tex]

      = [tex]\frac{1}{2} (e^{4x} -e^{2x} -e^{3x} + e^{x}[/tex]

and the coefficient is

[tex]\frac{1}{2} (4^r -2^r -3^r +1)[/tex]

The generating function is

G(x) = (x¹/1! + x²/2! + ...)⁴(x°/0! + x¹/1! + x²/2!+...)²² = ()⁴,

and we again want the coefficient of  X¹⁰/10!.

Multiplying we get,

G(x) = [tex](e^{4x} - 4e^{3x} + 2e^{2x} + 1)e^{22x}[/tex]

       = [tex]e^{26x} - 4e^{25x} + 2e^{24x} +e^{22x}[/tex]

so the coefficient of  X¹⁰/10! is

26¹⁰ - 4 × (25)¹⁰ + 2 × (24)¹⁰ + 22¹⁰

6 socks must be removed from the drawer to guarantee that at least two socks of same color have been removed.

It makes no difference how many socks there are; what matters is how many different colours of socks there are, as there are five different colours.

So, if 6 socks are taken from the drawer, it is almost certain that at least two of them will be the same colour.

Because, after taking 5 socks, you will either have a match or a difference. To ensure a matching pair, add one more sock.

You have a pair if the first five are the same colour. If none of the first five socks match, the sixth sock will match one of the first five.
