How do I draw and determine the equation of a trend line on a scatterplot

Answers

Answer 1

Step-by-step explanation:

Step 1: Draw your trend line.

You begin by drawing your trend line. You want your trend line to follow your data. You want to have roughly half your data above the line and the other half below the line, like this:

trend line equation

Step 2: Locate two points on the line.

Your next step is to locate two points on the trend line. Look carefully at your trend line and look for two easy to figure out points on the line. Ideally, these are points where the trend line crosses a clearly identifiable location.

For the trend line that we just drew, we can see these two easily identifiable points.

trend line equation

We can easily identify these two points as (3, 3) and (12, 6).

Step 3: Plug these two points into the formula for slope.

The formula for slope is this one:

trend line equation

We can label our first point as (x1,y1), and our second point as (x2,y2). So our x1 is 3, our y1 is 3, our x2 is 12, and our y2 is 6. Plugging these values into the equation for slope and evaluating, we get this:

trend line equation

So our slope is 1/3.

What formula do i use when it tells me to find the area with a given circumference? If you know please give an example as well, thank you.

Answers

Answer:

Step-by-step explanation:

A = C^2 / 4 x pi

so if the circumfernce was 10 you would square it to make it 100 and then you would do 4 x pi to get 12.57 ( rounded).

you would then just divide 100 by 12.57 = 7.96 ( rounded)

Step-by-step explanation:

The largest 6-digit number is:

We need all digits different and the last one 0 or 5 because the number is the multiple of 5.

9876 are the first 4 digits and the last two 50 or 45, we'll chose 50 as 45 is smaller.

So the number is:

Answers

Answer:

[tex] y = \dfrac{w}{h - 5t^2} [/tex]

Step-by-step explanation:

w = yh − 5yt^2

There is a y in each term on the right side. We factor it out.

w = y(h - 5t^2)

Now we divide both sides by h - 5t^2 to isolate y.

[tex] \dfrac{w}{h - 5t^2} = y [/tex]

[tex] y = \dfrac{w}{h - 5t^2} [/tex]

The perimeter of the triangular park shown on the right is 11x - 7. What is the missing length?

Answers

6x-4

Step-by-step explanation:

the perimeter is the distance around the shape, we get this by adding all the sides, call the missing side y and set up an equation for the perimeter

11x-7 = 4x+2 + x-5 + y

solve for y

11x-7 = 5x -3 + y

11x-4 = 5x + y

6x-4 = y

A taxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile traveled. The rule c = 0.40m + 1.75 describes the relationship between the number of miles m and the total cost of the ride c.
a. What is the charge for a 1-mile ride?
b. What is the charge for a 2.7-mile ride?


A. $2.15; $2.83


B. $0.40; $5.13


C. $0.40; $1.08


D. $1.75; $2.15

Answers

Answer:

A. $2.15; $2.83

Step-by-step explanation:

2.83

c = 0.4. * 2.7 + 1.75

=> c = 2.83

4(2.7)+1.75

1.08+1.75=2.83

$2.83 is correct.

c=0.40(2.7)+1.75

c=1.08+1.75

c=2.83

Answer:

2.83 dollars

Step-by-step explanation:

Fixed charges made by the taxi company for a ride =  

Additional charge for each mile travelled =  

Hence equation for cost is given by

where m is thenumber of miles travelled.

To find out the charge for a 2.7 mile ride substitute m = 2.7

Total cost for 2.7 mile ride is 2.83 dollars

The two dot plots below show the heights of some sixth graders and some seventh graders:

Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there are 2 dots for the fifth mark, there are 4 dots above the sixth mark.
