Answer:
IQR is 4, median is 58.
Step-by-step explanation:
Enter these values in a list, hit stat > calc > 1-var stats. That gives you the 5 number summary. To get IQR, subtract Q3 from Q1.
The hand went around 7 numbers.
The angles of a triangle add up to 180 degrees
180 - 80 = 100
Both of the unknown angles are the same. So...
100/2= 50
X = 50 degrees
If the three slashes are 190, 195, and 200, we can see it as
