<em>Note: You may have missed to add the dot plots chart, so I found the chart after a little research and hence, I am attaching it and based on that dot plot chart I am solving the question which anyways would clear you concept.</em>
Answer:
''The median for the students is 2 and the median for the teachers is 3'' is the right option which compares the medians of the data.
Step-by-step explanation:
Data for students from the dot plot in order
Calculating Median for students:
0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4
As you can see, we do not have just one middle number but we have a pair of middle numbers i.e. 2 and 2, so the median is the average of these two numbers:
Median = (2+2)/2
=4/2
= 2
Data for teachers from the dot plot in order
Calculating Median for teachers:
0, 1, 1, 1, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 6, 8
As you can see, we do not have just one middle number but we have a pair of middle numbers i.e. 3 and 3, so the median is the average of these two numbers:
Median = (3+3)/2
=6/2
= 3
Therefore, ''the median for the students is 2 and the median for the teachers is 3'' is the right option which compares the medians of the data.
The number of plates is an illustration of permutation and combination
The number of plates is 2592
<h3>How to determine the number of plates</h3>The range is given as: AVVJ 144 To: BVNP 199 (exclusive)
From the range, we have the following highlights:
- The first letter can be either A or B (i.e. 2 letters)
- The second letter can be only V (i.e. 1 letter)
- The third letter can be from W to M (24 letters)
- There are 54 numbers between 144 and 199
The number of plates (n) is then calculated as:
Evaluate the product
Hence, the number of plates (n) is 2592
