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 is 1 dot for the first mark, there are 3 dots above the second mark, 2 dots above the third mark.

The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.6. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.) (5 points)

0.3

b

Answer:

10.5 cm

Step-by-step explanation:

12÷9= 1.3 (1dp)

14÷(12÷9)= 10.5cm

Answer:

y = 10.5 cm

x = 80 degree

Step-by-step explanation:

Our approach is find measures first and y is our missing measure.

To find y

PQRS : ABCD   is in ratio the same as CD : RS

We need to work out CD : RS to find measures of  AD : SP

To find ratio we look at side measures first

CD : RS  = 12 : 9

12/9 = 1.333333

So that AD : SP   = 14 : ?

14 / 1.333333 = 10.50000

AD : SP =  14 : 10.5

y = 10.5 cm

To find x

We are given opposite angles and know with quadrilaterals they both share same opposite diagonal length ratios and share same opposite angles.

Where two angles are always in pairs given 100 degree can be multiplied by 2 and use the equation.

360 - (100 x 2) / 2  =  (360 - 200) / 2 = 160/2 = 80 degree

x = 80 degree

Answer:

d= 11

Step-by-step explanation:

C= πd

11π=πd

d= 11

A= πr²

Since r= d/2

A= π(11/2)²

A= 121/4π

Answer:

The range is 10

Step-by-step explanation:

since it starts at 0 and goes till 9 thats 10 data points

Answer:

9

Step-by-step explanation:

Okay, so range is just the difference between the highest and lowest values, and because the lowest is 0, it's just 9 - 0, which obviously equals 9

So the range of the data in the dot plot is 9

hope this helps:)

Answer:

50 degrees

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

The entire angle is 80 as shown.

The value of the missing angle can be found by using the following

F=80-30

F=50

Answer:

10/7 is a simple fraction, and √2 cannot be written as a simple fraction. So, they are not the same.

Step-by-step explanation:

10/7 is a number that has a numerator and a denominator.

Suppose √2 = 10/7, then √2 can also be written as a number that has a numerator and a denominator.

Since this is not the case, 10/7 cannot be the same as √2.

Answer:

L

Step-by-step explanation:

Pls mark me brainliest.

Answer:

Point L

Step-by-step explanation:

Point L is located at x, the horizontal coordinate, -3, 3 to the left, and is 0 units up/down, on the y coordinate.

x coordinate ALWAYS comes first, unless you're doing slope

Answer:

LMK is 30  

Step-by-step explanation:

inside the triangle, the LMN is the equation 3x=90degrees

under the KN is 4x

on the left is 150dgrees = 5x

3x+4x+5x=360

add the x's together

12x=360

divide

x=30

LMK= 150-90/2=60/2=30

Answer:

26 quarts

Step-by-step explanation:

[tex]6\frac{1}{2} = \frac{13}{2}\\\\3\frac{1}{2} = \frac{7}{2}[/tex]

Quarts                 Cake

  [tex]\frac{13}{2}[/tex]                        [tex]\frac{7}{2}[/tex]

   x                        14

find x.

Cross multiply to find x.

[tex]x \times \frac{7}{2} = 14\times \frac{13}{2}\\\\\frac{7x}{2} = 7 \times 13\\\\7x = 7 \times 13 \times 2\\\\x = \frac{7 \times 13 \times 2}{7} = 26[/tex]

So you need 26 quarts for 14 cakes

Answer:

(680/17) + (34/17) = 714

Step-by-step explanation:

714/17 = 42

714/17 = 40 + 2

40 x 17 = 680

2 x 17 = 34

680 + 34 = 714

Step-by-step explanation:

elimination of x:

-6x +5y = 1

6x + 4y = -10

___________+

9y = -9

y = -9/9 = -1

elimination of y:

-24x +20y = 4

30x + 20y = -50

_____________-

-54x = 54

x = 54/-54 = -1

{ -1, -1}

[tex]\huge{ \mathcal{  \underline{ Answer }\:  \:  ✓ }}[/tex]

The given equations are :

[tex]\longrightarrow - 6x + 5y = 1[/tex]

[tex]\longrightarrow6x + 4y = - 10[/tex]

let's add the equations

[tex] \longrightarrow\small{ - 6x + 5y +6x + 4y = 1 + ( - 10)}[/tex]

[tex]\longrightarrow9y = - 9[/tex]

[tex]\longrightarrow y = - 1[/tex]

now, let's plug the value of y in first equation :

[tex]\longrightarrow - 6x + (5 \times - 1) = 1[/tex]

[tex]\longrightarrow - 6x - 5 = 1[/tex]

[tex]\longrightarrow - 6x = 6[/tex]

[tex]\longrightarrow x = - 1[/tex]

Answer:

DO YOU STILL NEED HELP?

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

175.93 feet

Step-by-step explanation:

First, you divide 18 by 2 to get the radius which is 9. Then you do nine squared. Lastly, you do 64 times 3.14 to get 254.47 (rounded)

Now, you do 5 squared which is 25. Then you multiply 25 by 3.14 to get 78.54 (rounded).

Now you subtract

254.47 - 78.54 = 175.93

Note: I rounded these in the example, the decimal places still go on so the rounded answers may not subtract to the correct answers because all the decimal points weren't shown, but the answer is correct.
