below are the line plots for two data sets . Find the mean of each data set

Answer:

The slope is -2.

Step-by-step explanation:

1) The equation for a slope is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

2) Plug in x and y values into the equation. I plugged in (3,0) and (8,-10) into the equation.

3) You end up with: [tex]\frac{-10 -0}{8-3}[/tex], which simplifies down to [tex]\frac{-10}{5}[/tex], which equals -2.

Answer:

the slope is -2.

Step-by-step explanation:

plot the points on a graph, then draw a line through them. count the rise/run, which equals the slope.

Answer:

Answer= 50%

Step-by-step explanation:

7k=7000g

7000÷350=20

20x75p=1500p

1500=£15

£15 is £5 more than £10. £5 is half of £10 meaning its an extra 50%

Answer:

9.3 units

Step-by-step explanation:

By Pythagoras Theorem:

[tex] {x}^{2} + {(18 - 5)}^{2} = {16}^{2} \\ \\ {x}^{2} + {13}^{2} = {16}^{2} \\ \\ {x}^{2} + 169 = 256 \\ \\ {x}^{2} = 256 - 169 \\ \\ {x}^{2} = 87 \\ \\ x = \sqrt{87} \\ \\ x = 9.32737905 \\ \\ x \approx9.3[/tex]

Answer:

The 3rd from the choices is correct.

Answer:

2x+2x+2x= 180

6x=180

x= 30

Step-by-step explanation:

Answer: x=30

Step-by-step explanation:

Answer:

x = 111º

Step-by-step explanation:

In a heptagon, (A polygon with 7 sides, and therefore 7 angles), the sum of the interior angles is always 900º (just like the sum of all interior angle in a quadrilateral is always 360º). So you can add up all of the interior angles, and subtract them from 900º.

900º - (158º + 120º + 126º + 125º + 121º + 139º) = 111º

Answer:

Equation : y = 4.50D + 40

Number of pairs = 16

Step-by-step explanation:

It is given that:

Per day wage of Roger = $40

Commission on per pair of shoes = $4.50

Daily goal = $112

Number of pairs of shoes = D

Total earning = y

y = 4.50D + 40

112 = 4.50D + 40

4.50D = 112 - 40

4.50D = 72

Dividing both sides by 4.50

[tex]\frac{4.50D}{4.50}=\frac{72}{4.50}\\D = 16 \\[/tex]

Therefore,

Equation : y = 4.50D + 40

Number of pairs = 16

Answer:

Hey there,

The answer is below!!

Step-by-step explanation:

Knowing that those vectors start at the point (0,0) we can "think" them as lines.

As you may know, two lines are parallel if the slope is the same, then we can find the "slope" of the vectors and see if it is the same.

A) the vectors are: (√3, 1) and (-√3, -1)

You may remember that the way to find the slope of a line that passes through the points (x1, y1) and (x2, y2) is s = (y2 - y1)/(x2 - x1)

Because we know that our vectors also pass through the point (0,0)

then the slopes are:

(√3, 1) -----> s = (1/√3)

(-√3, -1)----> s = (-1/-√3) =  (1/√3)

The slope is the same, so the vectors are parallel.

Part B:

The vectors are: (2, 3) and (-3, -2)

the slopes are:

(2, 3) -----> s = 3/2

(-3, -2)----> s = -2/-3 = 2/3

the slopes are different, so the vectors are not parallel.

Answer:

yes, no, no, yes, no

Step-by-step explanation:

10:40 divide by 10 you get 1:4.  Correct

3:7 multiply by 3 and you get 9:21.  Incorrect

12:9 divide by 3 and you get 4:3.  Incorrect

25:15 divide by 5 and you get 5:3.  Correct

8:9 multiply by 2 and you get 16:18.  Incorrect

Answer:

15 degrees

Step-by-step explanation:

So you know that the sum of the two angles is 90 degrees, so you can make an equation:

[tex]3x + 45 =90[/tex]

Then, solve:

subtract 45 from both sides

[tex]3x = 45[/tex]

divide both sides by 3

[tex]x = 15[/tex]

This means that x = 15 degrees

Answer:

The answer is 15 degrees.

Step-by-step explanation:

1) Do you see the little square symbol at the bottom right corner? That represents that the angle is a right angle, or a 90 degree angle, in other words.

2) If you know that the first part of the angle is 45 degrees, as it is already labeled, then subtract 90 degrees - 45 degrees = 45 degrees, which is the angle that is left.

3) Set 3x equal to 45 degrees, and solve.

4) So, the equation is 3x = 45; divide by 3 on both sides to get x = 15 degrees.

Answer:

3.712 x 10^8

Step-by-step explanation:

use the commutative property to reorder the terms

(5.8x 6.4) x (10^5 x 10^2)

multiply 5.8 x 6.4 = 37.12

add 5+2=8

37.12 x 10^7

write the number in scientific notation

3.712 x 10^8

that'sur answer

Answer: 5.8 x 10^5 =

              6.4 x 10^2 =

Step-by-step explanation:

There is 5   10's because number of exponents are 5

so you multiply 5.8 by 10 10 10 10 10

The other is 6.4

multiply that by 10 10

But you can't multiply by all of that with one constant

So you answer the first one 10 x 10 x 10 x 10 x 10 = 100000

the other is 100

So now you multiply 5.8 by 100000

And multiply 6.4 by 100
