Factorizing the polynomial gives:

= 3x² + 6x - 2x  - 4

= 3x(x + 2) - 2(x + 2)

= (3x - 2)(x + 2)

The mean of the set of numbers is 4362.92

The median is 4164.5

The mode is 0.

It should be noted that the mean is the average sat of numbers. The addition of the numbers is 52355 and there are 12 numbers.

The mean will be:

= 51355 / 12

= 4362.92

The median is the number in the middle. This will be:

The number of miles that he walked is 4.5 miles. Then the number of laps that your friend walks will be 3 laps.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

A 9/10 miles long walkway around the lake. In the morning you walk three laps around the lake, and in the evening you walk two. On a 1 1/2 mile track, your companion walks the same overall distance as you do.

The number of miles that you walked will be

⇒ 9/10 x (3 + 2)

⇒ 9 x 5 / 10

⇒ 4.5 miles

Then the number of laps that your walk will be

Step-by-step explanation:

The arithmetic mean of a given data is the sum of all observations divided by the number of observations.

For example, a cricketer's scores in five ODI matches are as follows: 12, 34, 45, 50, 24. To find his average score in a match, we calculate the arithmetic mean of data using the mean formula:

Mean = Sum of all observations/Number of observations

Mean = Sum of all observations/Number of observations

Mean = (12 + 34 + 45 + 50 + 24)/5

Mean = 165/5 = 33

The value of the middlemost observation, obtained after arranging the data in ascending or descending order, is called the median of the data.For example, consider the data: 4, 4, 6, 3, 2. Let's arrange this data in ascending order: 2, 3, 4, 4, 6. There are 5 observations. Thus

median = middle value i.e. 4.

suppose Given data:

0, 40, 60, 70, 75, 80, 85, 95, 95, 100

a)Mean without '0' = 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100/9

                           = 700/9

                         = 77.777

Median without '0' = 80

Mean with ' 0' = 0+ 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100/10 = 70

Median with '0' = 80

b)standard deviation= 18.121673811445. (without '0')

Last week, Ella worked 16 hours after school and 8 hours before school using the concept of algebraic equations.

The equality of two mathematical expressions is demonstrated by a mathematical statement called an equation.

Algebraic equations in mathematics frequently have one or more variables.

Given: Ella makes $11.25 per hour before school and $11.75 per hour after.

Total earnings of Ella from = $278

Let x be the number of hours Ella worked before school.

Let y be the number of hours Ella worked after school.

11.25x + 11.75y = 278

Given that she works twice as long after school, it follows that

y = 2x

Substituting in the equation, we get

11.25x + 11.75(2x) = 278

11.25x + 23.5x = 278

34.75x = 278

x = 8

Similarly, y= 2x

y = 16

Ella accordingly worked 16 hours after school and 8 hours before school.

The required polynomial function is x^4 + 8x³ + 22x² + 24x + 9

In this question,

We have been given  the zeros of a polynomial and the degree of a polynomial.

We need to find the polynomial of degree 4 and has zeros x = -3, -1

If a polynomial function f(x) has zeros x = -3, x = -1, then it has factors

(x + 3), (x + 1).

If these were its only factors, then polynomial would be a quadratic.

This means, both the zeros must be of multiplicity 2.

So, the roots of the polynomial must be of the form f(x) = (x + 3)²(x + 1)²

f(x) = (x + 3)²(x + 1)²

f(x) = (x² + 6x + 9)(x² + 2x + 1)

f(x) = x^4 + 8x³ + 22x² + 24x + 9

Therefore, the required polynomial function is x^4 + 8x³ + 22x² + 24x + 9

we conclude that the equation x + 10 = 5 has only one solution, which is x = -5

Here we have the linear equation:

x + 10 = 5

In general, linear equations have only one solution, but let's solve this to see how many solutions it has.

If we subtract 10 in both sides of the linear equation, we will get:

x + 10 - 10 = 5 - 10

x = -5

So there is a single solution, which is x = -5.

Given the volume, length and height, the width of the rectangular prism rounded to the nearest foot is 8ft.

The volume of a rectangular prism is expressed as;

V = w × h × l

Where w is the width, h is height and l is length.

Given the data in the question;

To determine the with of the rectangular prism, plug the given values into the formula above and solve for w.

V = w × h × l

528 ft³ = w × 11ft × 6ft

528 ft³ = w × 66ft²

Reorder the equation and divide both sides by 66ft²

w × 66ft = 528 ft³

( w × 66ft )/66ft² = 528 ft³ / 66ft²

The equation of a straight line that is parallel to y = 2x -8 and passes through the point (0,-3) is  y=2x-3 .

The general equation of straight line is of the form y=mx+c where m is the slope of the equation and c is the y-intercept of the equation.

The slope is defined as the tangent of the angle made by the line with the positive direction of x axis.

he y-intercept of a straight line is the point where the graph passes the y-axis.

The given equation of the line is y=2x-8. Comparing the given equation with the general equation of a straight line we can conclude that the slope of the line is 2.

Two parallel lines have the same slope . Therefore the slope of the line parallel to y = 2x -8 is also 2.

We know that if a line with slope m passes through(x₁, y₁) then the equation of the line is given by

y-y₁=m(x-x₁)

The required line passes through (0,-3)

∴putting the values we get:

y-(-3)=2(x-0)

or, y+3=2x

or, y=2x-3

Therefore the line parallel to  y = 2x -8 and passing through the point (0,-3) is y=2x-3.
