Answer:
The median of the list is 26.
Step-by-step explanation:
Since the <u>mode of the list is 26</u>, and so far we only have one occurrence of 26 in the list, we know that one of our unknowns must equal 26.
If we set x = 26, we can then s<u>olve for y using the arithmetic mean formula. </u>We are left with:
.
Solving for y leaves us with y=43.
Finally, we can put the list in order and find the middle values. Since the two middle values are 26, the median of the list is 26.
