Cars lose value the farther they are driven. A random sample of 11 cars for sale was taken. All 11 cars were the same make and model. A line was fit to the data to model the relationship between how far each car had been driven and its selling price.

Answers

Answer 1

Answer:

[tex]y=-\frac{1}{4}x+40[/tex]

Step-by-step explanation:

Given

See attachment for graph

Required

Determine the equation of the line of best fit

First, calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

From the graph, we can have:

[tex](x_1,y_1) = (20,35)[/tex]

[tex](x_2,y_2) = (60,25)[/tex]

So, the slope is:

[tex]m = \frac{25 -35}{60 - 20}[/tex]

[tex]m = \frac{-10}{40}[/tex]

[tex]m = -\frac{1}{4}[/tex]

The equation is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = -\frac{1}{4}(x - 20) + 35[/tex]

[tex]y = -\frac{1}{4}x + 5 + 35[/tex]

[tex]y=-\frac{1}{4}x+40[/tex]

Hence, the equation is: [tex]y=-\frac{1}{4}x+40[/tex]

Rohit rode his bike 5 2/3
miles. Sarah rode her bike 5 1/5
miles. Write an inequality that compares the fractions. Explain in a sentence who rode a greater distance.

Answers

Answer:

as a decimal 5 2/3 would be 5.67 rounded to the nearest hundredth. As a decimal 5 1/5 5.2 to the nearest tenth.

Rohit rode his bike a greater distance because 5 2/3 is only 1/3 away, while 5 1/5 is 4/5 away.

Step-by-step explanation:

You just carpeted a 9 x 12 foot room for $480. The carpet is priced by square foot. About how much would you expect to pay for the same carpet in another room that is 21 x 28 feet?

(With explanation)

Answers

First you would find the amount of money you’d need by square foot which you can find by multiplying 9 by 12 then dividing 480 by that number (which is 108) that will give you approximately $4.44 per square foot.

Next you would multiple 21 by 28 to find out the amount of square feet in that room (which is 588) then you can multiply that by $4.44 to get $2,610.72.

So you will expect to pay $2,610.72 for a 21 x 28 room

Answer:

ok so..to find out the amount it cost per square foot you have to multiply 9*12=108 ft

108ft=$480

$480/108=4.44~~~~~it's continuous

so then multiply 21*28=588

588*4.44~~~~=2613.33~~~~its continuous too.

Step-by-step explanation: answer is

=$2613.33 ~~~~its continuous too.

How to determine the period?

The period of a sine function is calculated using:

T = 2π/B

When B = 0.5, we have:

T = 2π/0.5

T = 4π

When B = 2, we have:

T = 2π/2

T = π

Hence, the periods when B = 0.5 and 2 are 4π and π, respectively

Answer:

48 degrees

Step-by-step explanation:

1) Solve for x

Complementary angles add up to 90 degrees. Therefore, m<A + m<B is equal to 90:

[tex]A+B=90\\(2x+20)+(3x)=90[/tex]

Open up the parentheses

[tex]2x+20+3x=90\\5x+20=90[/tex]

Subtract 20 from both sides

[tex]5x+20-20=90-20\\5x=70[/tex]

Divide both sides by 5

[tex]\frac{5x}{5} =\frac{70}{5} \\x=14[/tex]

Therefore, x is equal to 14.

2) Determine angle A

[tex]A=2x+20[/tex]

Substitute x with 14

[tex]A=2(14)+20\\A=28+20\\A=48[/tex]

Therefore, the measure of angle A in degrees is 48 degrees.

A school group is raising money for a trip. The group needs $450 for travel and $325 for food. They have 6 weeks to raise money selling $1 candy bars.
What is the least number of candy bars the group needs to sell each week to afford the trip?

Answers

Answer:

Step-In total, the amount of money they will need to raise is:

= 450 + 325

= $775

by-step explanation:

They have 6 weeks to raise this money so the amount they have to raise per week is at least:

= 775/6

= $130

The candy bars cost $1 each. They will therefore have to sell a minimum of 130 candy bars each week to afford the trip.

Answers

Answer:

It decreased 60%

Step-by-step explanation:

TO figure this out we must first find 1% of 60

60/100 = .6

Now we find the difference between 60 and 24

60 - 24 = 36

Now that we know how much it decreased we must now find out what percent 36 is of 60.

.6 x 60 = 36

So 36 out of 60 is 60%

So it decreased 60%

Which table contains only values that satisfy the equation y= 0.5x+14?

Answers

Answer:

Step-by-step explanation:

The values of the variables x and y in table C is satisfying the equation y = 0.5x + 14.

What is a linear equation?

The linear equation is defined as the equation having a degree of one or the power of the variable will be one.

The table data is,

x y

0 14

5 16.5

10 19

15 21.5

20 24

The table data is satisfying the equation y = 0.5x + 14.

At ( 0,14)

y = 0.5x + 14.

14 = 0 + 14

14 = 14

At ( 5,16.5)

16.5 = (0.5 x 5) + 14

16.5 = 2.5 + 14

16.5 = 16.5

At (10.19)

19 = (0.5 x 10 ) + 14

19 = 5 + 14

19 = 19

Therefore, the values of the variables x and y in table C is satisfying the equation y = 0.5x + 14.
