Answer:
<h2>1 </h2>Step-by-step explanation:
A data arranged in descending order is a data arranged from the biggest to the smallest. The medisn of the data sets is the value at the middle of the dataset after rearrangment.
For the dataset {8, x, 4,1}, the median will be x and 4. Since we have two median values, we will take their average as shown
Median(1) = ... 1
Simialrly for dataset {9, y, 5,2}, the median will be y and 5.
Median(2) = ...2
Since the medians of the two given datasets are equal, we will equate equation 1 and 2 and calculate for y-x as shown;
Therefore y-x = -1
(y-x)² = (-1)²
= 1
