Answer:
5 people brought 1 dish & 9 people brought 2 dish
Step-by-step explanation:
We can create a system of equations (2 equations) in solving this problem.
Let x = number of people that brought 1 dish
Let y = number of people that brought 2 dish
Total, 14 people came, so we can write:
x + y = 14
[ or x = 14 - y ]
In total there were 23 dishes, remember x is 1 dish people and y is 2 dish people, so we can write:
1x + 2y = 23
or x + 2y = 23
Now, putting 1st equation into 2nd equation, we get an equation in y and solve for y first. Shown below:
x + 2y = 23
14 - y + 2y = 23
y = 23 - 14
y = 9
Now, finding x:
x = 14 - y
x = 14 - 9
x = 5
So, 5 people brought 1 dish & 9 people brought 2 dish

Step-by-step explanation:
The median of a data set is found by putting the data set in ascending numerical order and identifying the middle number. If there are an odd number of data values in the data set, the median is a single number. If there are an even number of data values in the data set, the median is the average of the two middle numbers. Sorting the data set for the values entered above we have:
Since there is an even number of data values in this data set, there are two middle numbers. With 8 data values, the middle numbers are the data values at positions 4 and 5. These are 16 and 18. The median is the average of these numbers. We have
Therefore, the median is
