What Is The Sum Of The Squared Distances From The Mean?

Answers

Answer 1

Answer:

The sum of squares is the sum of the square of variation, where variation is defined as the spread between each individual value and the mean. To determine the sum of squares, the distance between each data point and the line of best fit is squared and then summed up. The line of best fit will minimize this value.

16. Marique is making a large table in the shape of a trapezoid. She needs
to calculate the area of the table. The longest side of the table is twice
as long as the table's width. Find the area of the table by decomposing
the trapezoid into familiar shapes. Show your work

Answers

Given that the length of the table is twice the width which is 1.25 m. and

the difference in the parallel side is 1 m., the area of the table is 2.5 m².

How can the area of the table be calculated?

The possible table dimensions are;

Width of the table = 1.25 m

Width of the table = The height of the trapezoid

The difference in length between the parallel sides = 2 × 0.5 m = 1 m

Longest side of the table is a parallel side of the trapezoid

Given;

Length of the longest side of the table = 2 × The width

Which gives;

Length of the longest side of the table = 2 × 1.25 m = 2.5 m

Length of other parallel side = 2.5 m - 1 m = 1.5 m

[tex]Area \ of \ a \ trapezoid = \mathbf{\dfrac{Sum \ of \ length \ of \ parallel \ sides}{2} \times Height}[/tex]

Which gives;

[tex]\mathbf{Area \ of}\ the \ \mathbf{table} = \dfrac{2.5 + 1.5}{2} \times 1.25 = 2.5[/tex]

The area of the = 2.5 m²

Learn more about the properties of a trapezoid here:

https://brainly.com/question/4758162

— length of the longest side of the table = 2 × width which gives you 'length of the longest side of the table = 2 × 1.25 meters' which equals 2.5 meters. to find length of other parallel side use the equation 2.5 meters minus 1 meter, which is 1.5 meters. lastly to find the area, do  [tex]\frac{sum of length of parallel sides}{2}[/tex] multiplied by the height, which afer you fill it out turns into [tex]\frac{2.5+1.5}{2} *1.25[/tex] , which equals 2.5 meters. so the area is 2.5 meters squared.

So that means 15/3=5

So m=5


also I don’t know if this is correct….:/

m=5

Step-by-step explanation:

step 1:letters to the left side of the =, numbers to the right (If there are numbers attached to the letter, keep it on the left) if a number is being taken to the right, change the sign to the opposite of what it was

3m= 5+10

step 2: add the numbers on the right

3m=15

step 2: divide both sides by 3 to get m alone

m=5

Consider the line 7x+5y=−2.
What is the slope of a line perpendicular to this line?

What is the slope of a line parallel to this line?

Answers

Answer:  slope of a line perpendicular is [tex]\frac{5}{7}[/tex]; slope of a line parallel to this line is [tex]-\frac{7}{5}[/tex].

Step-by-step explanation:

Rewrite the line in y = mx + b form, where m is slope and b is y-intercept.

7x + 5y = -2

       5y = -7x -2

         y = [tex]-\frac{7}{5}[/tex]x - [tex]\frac{2}{5}[/tex]

The product of two slope of perpendicular line is -1.

Let x be the other line that perpendicular line with the line 7x + 5y = -2.

([tex]-\frac{7}{5}[/tex])x = -1

        x = [tex]\frac{5}{7}[/tex]

The slope of a line parallel to this line is the same, which is [tex]-\frac{7}{5}[/tex].

Tasha is planning an expansion of a square flower garden in a city park. If each side of the original garden is increased by 10 m, the new total area of the garden will be 169 m2. Find the length of each side of the original garden

Answers

Answer:

6m

Step-by-step explanation:

To find the original length you must take away the add-ons. To do so we know that they added 7 and A= l*l (or l squared). They added the 7 to the length so multiply 7*7 (49) subtract your answer from 169 (120) and that's your new area. To find the original length divide by 4 (I believe) and get 30m2

The equation of the graph of the polynomials is f ( x ) = x² ( x - a )⁵ ( x - b )

What is Equation of Graph of Polynomials?

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x² ( x - a )⁵ ( x - b )

From the graph of the polynomial , we can see that

The critical points of the function f(x) = x² ( x - a )⁵ ( x - b ) are x = 0, x = a, x = b, and x = (7a + 5b)/3

Hence , the function is f ( x ) = x² ( x - a )⁵ ( x - b )

Answers

Step-by-step explanation:

x³ - y³ = (x - y)³ + 3x²y - 3xy²

28 = (2)³ + 3xy(x - y)

28 = 8 + 3xy(2)

28 - 8 = 6xy

20 = 6xy → xy = 20/6 = 10/3

(x - y)² = 2²

x² - 2xy + y² = 4

x² - 2(10/3) + y² = 4

x² + y² = 4 + 20/3 = 32/3

x² + xy + y² = 32/3 + 10/3 = 42/3 = 14

2. how much water is in each tank after 3 hours?
tank one ___

tank two___

Answers

The equation for the first tank will be 175 - 25h and the equation for the second tank is 200 - 25h.

How to solve the equation?

From the information given, the first tank holds 175 gallons of water and the second tank holds 200 gallons of water while the hoses that she uses drain the tanks at a rate of 25 gallons of water per hour.

Therefore, the equation for the first tank will be:

= 175 - (25 × h)

= 175 - 25h

The equation for the second tank will be:

= 200 - (25 × h)

= 200 - 25h

The quantity in the first tank after three hours will be:

= 175 - 25h

= 175 - (25 × 3)

= 175 - 75

= 100 gallons.

The quantity in the second tank after three hours will be:

= 200 - 25h

= 200 - (25 × 3)

= 200 - 75

= 125 gallons.
