Is 2/3 < 5/8? Help me with this

For the regression equation and e the number of kilowatt-hours, in thousands, for a six-room house  is mathematically given as

Y = 1.33-0.667X and  5.3332

Generally, the equation for the  standard deviation  is mathematically given as

[tex]s[/tex]ₓ =[tex]\sqrt{\frac{\sum\(X-\=X)^2}{n-1} }[/tex]

= [tex]\sqrt{\frac{66.9}{10-1} }[/tex]

= 2.72

[tex]s_y[/tex] = [tex]\sqrt{\frac{36.4}{10-1} }[/tex]

= 2.01

therefore correlation coff

r = [tex]\frac{44.6}{(10-1)(2.72)(2.01)}[/tex]

r = 0.9038

In conclusion the regression equation is given

b = r_sy/sx

b = (0.9038)(2.01/2.72)

 = 0.667

intercept

a = 7.4-0.667(9.1)

a = 1.33

The regression equation is

Y = 1.33-0.667X

(b) number of kilowatts x = 6 house

Y = 1.33-0.667X

Y = 1.33-0.667(6)

 = 5.3332

Answer:

(5, 1 )

Step-by-step explanation:

3x + 3y = 18 → (1)

5x + 3y = 28 → (2)

subtract (1) from (2) term by term to eliminate y

(5x - 3x) + (3y - 3y) = 28 - 18

2x + 0 = 10

2x = 10 ( divide both sides by 2 )

x = 5

substitute x = 5 into either of the 2 equations and solve for y

substituting into (1)

3(5) + 3y = 18

15 + 3y = 18 ( subtract 15 from both sides )

3y = 3 ( divide both sides by 3 )

y = 1

solution is (5, 1 )

The predicted number of students is an illustration of ratios

Of the 1600 students, 640 are expected to have a rap as their favorite type of music

The given parameter can be represented using the following ratio:

Ratio = Rap : Total Students

So, we have:

30 : 75 = Rap : 1600

Express as fraction

30/75 = Rap/1600

Multiply both sides by 1600

Rap = 640

Hence, 640 of the 1600 students are expected to have a rap as their favorite type of music

Answer:

y = -4x+7 is the equation simplified and answer choice A is the right answer.

Step-by-step explanation:

Your equation: y - 6 = -4(x+1)

Your Objective: You need to simplify the original equation and find another equation that is equivalent to the original equation.

Let's focus on the -4(x+1) side first.

This needs to have the distributive property applied.

Take -4 and multiply it by x and 1.

You should have -4x+1

Your equation now:

y - 6 = -4x+1

We want y to be by itself.

So add 6 to both sides.

y = -4x+1+6

Use PEMDAS

y = -4x+7

The first answer choice "A" is correct.

Dilate by a scale factor of 0.5 with the origin as the center of dilation.

Rotate 90° clockwise about the origin

Step-by-step explanation:

Polygon ABCD:

Dilate by a scale factor of 0.5 with the origin as the center of dilation (pink polygon on attached diagram).

This means multiply the x and y values of the points by 0.5:

A → (-1, 2)

B → (-4, 1)

C → (-2, 4)

D → (-1, 3)

Rotate 90° clockwise about the origin: (x, y) → (-y, x)

A' = (-2, 1)

B' = (-1, 4)

C' = (-4, 2)

D' = (-3, 1)

So the transformations are:

Answer:

13:192 in2

Step-by-step explanation

with the pythagoras theorem you can find the base =6

base x height /2= area =24

two triangles=24.2 =48

square one side =12

area=12.12=144

area of the shape = 144+48=192

Using the pythagorean theorem, we can calculate the base of the right triangle to be 6 (1 triangle)

-> The triangle's base length is 12.

So, the square's length is also 12.

We can now calculate the area of the figure : 12 x 12 + 12 x 8 : 2 = 192 in2

Answer:

452

Step-by-step explanation:

5424/12 is equal to 452

Each person pay $452.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

A group of 12 friends bought a boat costing $5,424.

Now,

Since. A group of 12 friends bought a boat costing $5,424.

Hence, The cost of each person pay = $5,424 / 12

                                                         = $452

Thus, Each person pay $452.

Answer:

X = 8 And y = 1/5

Step-by-step explanation:

add equaction i and education ii,

2 -5y = 1

2x +5y = 17

------------------

2+2x = 18

or, 2x = 18 - 2

or X = 16/2

or X = 8

Again from equation i,

2 - 5y = 1

or, -5y = 1 - 2

or, -5y = -1

or, y = -1/-5 (cut the subtraction sign)

or, y = 1/5
