Answer:
Step-by-step explanation:
x^2 + 44^2 = 55^2
x^2 + 1936 = 3025
3025-1936 = 1089
sqrt(1089) = 33
x = 33

Step-by-step explanation:
The interquartile range is a measure of how spread out values are in a data set.
It doesn't actually consider the values, it is found by finding the range between the Q1 / 25th percentile and the Q3 / 75th percentile --and a "range" is found by finding the difference between these two numbers (by subtracting).
So, the weather could have been something like:
79 79 79 80 81 81 83 85 96 97
79 79 79 80 81 | 81 83 85 96 97
meaning that the interquartile range is 6, but these temperatures are not low
(if you want me to explain how to find the interquartile range more thoroughly, please let me know)
