Step-by-step explanation:

A dot plot is a chart that is created using data points. It is one of the easiest ways of plotting the distribution of data and they make it a lot easier to see data. It is like a bar chart but instead of bars, you have dots.

It is created by counting the number of data that a particular variable has and drawing the corresponding number of dots above it.

Answer:

Angle between the diagonal of a cube of side length 8 and the diagonal of one of its faces is equal to [tex]0.6155[/tex] radian

Step-by-step explanation:

Please see the attached image for better understanding

Length of OB is equal to

[tex]\sqrt{19^2 + 19^2 }[/tex]

[tex]19\sqrt{2}[/tex]

Now the length of OE is equal to

[tex]\sqrt{19^2 + 19^2 + 19^2 } = 19 \sqrt{3}[/tex]

Now Angle BOE is equal to

[tex]cos^{-1} (\frac{722}{19\sqrt{2}* 19\sqrt{3} }) = 0.6155[/tex] radians

Angle between the diagonal of a cube of side length 8 and the diagonal of one of its faces is equal to [tex]0.6155[/tex] radian

Answer:I think it is 82

Step-by-step explanation: because a straight line is 180° and 180-98=82

Answer:

<A = 62

Step-by-step explanation:

<A and <B add up to 90 degrees. Definition of Complementary.

<A + <B = 90

(6x - 4) + (x + 17) = 90

7x + 13 = 90

7x = 77

x = 11

<A = 6x - 4

<A = 6(11) - 4

<A = 66 - 4

<A = 62

Answer:

18÷5= 3.6

3.6 = 4 yards

72 yards of cloth ÷ 4 yards of cloth = 18 pants

Step-by-step explanation:

3.6 yards rounded to the nearest is 4. So it takes 4 yards of cloth to make 1 pants. Since it takes 4 yards of cloth to make 1 pants, we simply divide 4 yards into 72 yards which equals to 18 pants.

Answer:

8506.5

Step-by-step explanation:

1 km = 1000 meter

2.5 km = 2.5 * 1000 =                                        2500 meters

5250 m does not require any conversion      5250 meters

1 meter = 100 cm

75650 cm   = 75650/100                                   756.5 meters

Total                                                                    8506.5 meters

Answer:

This would be a 60% increase

Step-by-step explanation:

40-25 and divided by 25 times 100

you should get 15/25 multiply it by 100=60%

this question is incomplete, the complete question is:

1. is this model effective

2. what is the correlation coefficient for this data.

3. for a student with a bmi of 25, what is the predicted number of hours under the influence.

Step-by-step explanation:

1. first of all this model is not effective because we have r² as 0.134. this tells us that only 13.4 percent of the of the variations that exist in this data has been explained by the model

1. we get the correlation coefficient by

[tex]+-\sqrt{r^{2} }[/tex]

the regression slope coefficient has a negative sign. this is what we would use in calculating the correlation coefficient.

[tex]-\sqrt{r^{2} }[/tex]

= -√0.134

= -0.366

therefore the correlation coefficient is -0.366

2. to get the number of hours under the influence with a bmi of 25

the equation is

49.2-1.15bmi

= 49.2-1.15(25)

= 49.2-28.75

= 20.45

Answer:

Parallel lines ALWAYS have the same slope

Step-by-step explanation:

The equations have unequal slopes, meaning they aren't parallel.

Answer:

median

Step-by-step explanation:

For a group of data with one big outlier, the mean is thrown off.

Like a room of 10 people who each make $50,000 a year except for one person who makes $2 million a year. The mean average for that group would be $245,000 a year but it reflects the actual circumstance of NOBODY in the room.

The median is more refective of the 'average' in these situations.

Can you clarify the syntax?  what goes where the '??' is below?

Step-by-step explanation:

32x^2 -48    ??   2x+8x  

Answer:

[tex]\begin{array}{cccc}{Class} & {Frequency} & {Relative Frequency} &{Percent\ Frequency}\ \\ {12-14} & {2} & {0.05} & {5\%}& {15-17} & {8} & {0.200}&{20\%}& {18-20} & {11} & {0.275} & {27.5\%}& {21-23} & {10} & {0.250} &{25\%}& {24-26} & {9} & {0.225}&{22.5\%} & {Total} & {40} & {1} & {100\%}\ \end{array}[/tex]

Step-by-step explanation:

Required

Complete the table.

First, group the data according to the class.

So, we have:

12-14:- 14 12 --- Frequency is 2

15 - 17:- 16 16 16 16 16 17 16 15 --- Frequency is 8

18 - 20:- 19 19 19 18 19 18 20 20 19 20 20 --- Frequency is 11

21 - 23:- 21 23 21 22 21 23 23 22 22 22 --- Frequency is 10

24 - 26:- 25 24 24 25  25  24 26  24  24 --- Frequency is 9

Next, fill the class frequency column

[tex]\begin{array}{cc}{Class} & {Frequency} \ \\ {12-14} & {2} & {15-17} & {8} & {18-20} & {11} & {21-23} & {10} & {24-26} & {9}\ \end{array}[/tex]

Relative frequency is calculated by dividing each frequency by the total frequency (40).

So, we have:

[tex]\begin{array}{ccc}{Class} & {Frequency} & {Relative Frequency}\ \\ {12-14} & {2} & {0.05} & {15-17} & {8} & {0.200}& {18-20} & {11} & {0.275} & {21-23} & {10} & {0.250} & {24-26} & {9} & {0.225}\ \end{array}[/tex]

The percent frequency is calculated by multiplying the relative frequency by 100%.

So, we have:

[tex]\begin{array}{cccc}{Class} & {Frequency} & {Relative Frequency} &{Percent\ Frequency}\ \\ {12-14} & {2} & {0.05} & {5\%}& {15-17} & {8} & {0.200}&{20\%}& {18-20} & {11} & {0.275} & {27.5\%}& {21-23} & {10} & {0.250} &{25\%}& {24-26} & {9} & {0.225}&{22.5\%} & {Total} & {40} & {1} & {100\%}\ \end{array}[/tex]
