The dot plot and box plot show different displays of the ages of runners on a track team. which statements best describe the dot plot or box plot? check all that apply. -add the number of dots above each age in the dot plot to find the number of players on the team: 2 + 1 + 3 + 2 + 3 + 2 = 13. -subtract the maximum and minimum values of the box plot to find the number of players on the team: 12 – 7. -the median appears clearly on the dot plot at the center of the number line: 9.5. -the median appears clearly on the box plot at the line within the box: 10. -the dot plot is the only display that can be used to show the variability of the data. -the box plot is the only display that can be used to show the variability of the data.

The correct options are 1 and 4.

Step-by-step explanation:

From the dot plot it notices that

Age                        frequency

  7                                  2

  8                                  1  

  9                                  3

 10                                  2

 11                                   3

 12                                  2

Total                              13

Add the number of dots above each age in the dot plot to find the number of players on the team: 2 + 1 + 3 + 2 + 3 + 2 = 13.

Therefore option 1 is correct and option 2 is incorrect.

From the box plot it is noticed that

The median is 10, therefore option 3 is incorrect and option 4 is correct.

There are many charts and plots that are used to show the variability of the data. Like Histogram, box plot, dot plot, scatter plot, etc. Therefore options 5 and 6 are incorrect.

The correct answers is 2) The Eagles have more variability in the ages of their players and 4) The Eagles have more players.

Step-by-step explanation:

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
