Answer:

The usual representation of a proportional relationship is ...

y = kx

You want the constant of proportionality (k) to be 7/10, so this is ...

y = (7/10)x

Dividing by x gives the equivalent relationship ...

y/x = 7/10

Step-by-step explanation:

The absolute difference is estimated as $2.9 million and relative difference is calculated as 26%.

The absolute change refers to the actual increase or decrease from the a reference value to a new value:

absolute difference = new value - reference value

In the given question, the reference value is given as $10.8 million.

The new value is $13.7 million.

absolute difference = 13.7 - 10.8

absolute difference = 2.9

Thus, the absolute value if estimated as $2.9 million.

The absolute difference is described as a fraction of a reference value by the relative difference:

The formula for calculating the relative difference is;

relative difference = (new value - reference value)/reference value

relative difference = absolute difference/reference value

Substituting the values;

relative difference = 2.9/10.8

relative difference = 0.26

relative difference% = 0.26×100%

relative difference = 26%.

Thus the relative difference is estimated as 26%.

Answer:

Elisa made the greater number of withdrawals.

Step-by-step explanation:

Given that:

Elisa withdrew $20 at a time and a total amount of $140

Number of withdrawals by Elisa = [tex]\frac{Total\ amount\ withdrawn}{Amount\ withdrawn\ each\ time}[/tex]

Number of withdrawals by Elisa = [tex]\frac{140}{20}=7[/tex]

Francis withdrew $45 at a time and a total amount of $270

Number of withdrawals by Francis = [tex]\frac{270}{45}[/tex]

Number of withdrawals by Francis = 6

On comparing;

7 > 6

Hence,

Elisa made the greater number of withdrawals.

Sorry to say but I don't see any material.

Step-by-step explanation:

The equation in the form y = mx + b is y = 0.35x + 36.

The equation formed from the expression is a linear equation and should be expressed in the slope intercept form.

y = mx + b

where

Therefore,

y = mx + b

where

using the coordinates, let's find m

(470, 200.5)(590, 242.5)

Hence,

m = 242.5 - 200.5 / 590 - 470

m = 42 / 120

m = 0.35

Therefore,

y = 0.35x + b

200.5 = 0.35(470) + b

200.5  - 164.5 = b

b = 36

Finally, the equation in the form y = mx + b is y = 0.35x + 36.

Answer:

Step-by-step explanation:

The new price of the used compact car is $30,360 if the used automobile dealership recently reduced the price of a used compact car by 12%.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

A used automobile dealership recently reduced the price of a used compact car by 12%.

The price of the car before the discount = $34,500

The new price can be found using:

= 12% of $34,500

= (12/100)x34,500

= 0.12x34,500

The reduced amount = $4140

The new price = 34500 - 4140

The new price = $30,360

Thus, the new price of the used compact car is $30,360 if the used automobile dealership recently reduced the price of a used compact car by 12%.

Step-by-step explanation:

A linear function has exactly one output to each input.

The given function has both negative associations and assigns exactly one output to each input. Options C and D both are correct.

Given that,
Thomas has graphed the function y = 7x – 10 on a coordinate plane.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,

As the function is the equation of the straight line that implies it gives exactly one output to each input and has negative input or negative association to sub-function 7x.

Thus, the given function has both negative associations and assigns exactly one output to each input. Options C and D both are correct.

Step-by-step explanation:

Marks gotten by the 5 students are;

15, 14, 20, 17, 25

Marks more than or equal to 20 are 2 in number namely 20 and 25.

Thus, probability of getting marks more than or equal to 20 is;

P(marks ≥ 20) = 2/5

P(marks ≥ 20) = 0.4

Answer:

Hi, the answer would be that Peter has 570 pages in total.

Step-by-step explanation:

Since he has 5 books with 100 pages, you multiply 5 by 100

5 × 100 = 500

Next, Peter has 7 books with 10 pages each, so you multiply 7 by 10.

7 × 10 = 70

Next, you can add them together to get the total.

500 + 70 = 570

570 is the total.

Hope this helps!

570

Step-by-step explanation:

Because 5 multipled by 100 is 500

Answer:

This is a sphere with a center  [tex](\dfrac{8}{3},\dfrac{8}{3},\dfrac{8}{3} )[/tex]  and radius [tex]\dfrac{4 \sqrt{3}}{3}[/tex]

Step-by-step explanation:

Given that: (x,y,z)

where;

d₁ is the distance from the origin = [tex]\sqrt{x^2+y^2+z^2}[/tex]

d₂ is the distance from (2,2,2) = [tex]\sqrt{(x-2)^2+(y-2)^2+(z-2)^2}[/tex]

Also;

d₁ = 2d₂

[tex]\sqrt{x^2 + y^2 +z^2 } = 2 \sqrt{(x-2)^2 +(y-z)^2+(z-2)^2}[/tex]

By squaring both sides;

[tex]x^2 + y^2 +z^2 = 2^2((x-2)^2 +(y-z)^2+(z-2)^2)[/tex]

[tex]x^2 + y^2 +z^2 = 4(x-2)^2 +4(y-z)^2+4(z-2)^2[/tex]

[tex]x^2 + y^2 +z^2 =4(x^2 -2x -2x +4) + 4(y^2 -2y -2y +4) + 4(z^2 -2z-2z+4)[/tex]

[tex]x^2 + y^2 +z^2 =4x^2 -16x +16 + 4y^2 -16y +16 + 4z^2 -16z+16[/tex]

Collect the like terms:

[tex]0 = 4x^2 -x^2 -16x +16 + 4y^2 -y^2 -16y +16 +4z^2 -z^2 -16z +16[/tex]

[tex]0 = 3x^2 -16x +16 + 3y^2 -16y +16 +3z^2 -16z +16[/tex]

Divide both sides by 3

[tex]\dfrac{0}{3} = \dfrac{3x^2 -16x +16}{3} + \dfrac{3y^2 -16y +16 }{3} + \dfrac{ +3z^2 -16z +16}{3}[/tex]

[tex]0 = {x^2 - \dfrac{16x}{3} +\dfrac{16}{3} + {y^2 - \dfrac{16y}{3} +\dfrac{16}{3}+{z^2 - \dfrac{16z}{3} +\dfrac{16}{3}[/tex]

Using the completing the square method;

[tex]3(\dfrac{160}{9}) -16 = {x^2 - \dfrac{16x}{3} +\dfrac{160}{9} + {y^2 - \dfrac{16y}{3} +\dfrac{160}{9}+{z^2 - \dfrac{16z}{3} +\dfrac{160}{9}[/tex]

[tex]\dfrac{16}{3}= (x - \dfrac{8}{3})^2+ (y - \dfrac{8}{3})^2+ (z - \dfrac{8}{3})^2[/tex]

∴

This is a sphere with a center  [tex](\dfrac{8}{3},\dfrac{8}{3},\dfrac{8}{3} )[/tex]  and ;

radius; [tex]\sqrt{\dfrac{16}{3}}[/tex]

Answer: the width is 6.25 ft

And the Length is 18.75 ft

Step-by-step explanation:

Length = 3w

Width = w

Perimeter = 3w + 3w + w + w

50 = 3w + 3w + w + w

50 = 8w

w = 6.25

Length = 3w

Length = 3(6.25)

Length = 18.75

Therefore the width is 6.25 ft

And the Length is 18.75 ft
