Find the area of each triangle to the nearest tenth

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.
