Answer:
r=198cm
Step-by-step explanation:
88pi = 2pi * r * 80/360
Answer:
Median = 5
Lower Quartile = 2.5
Upper Quartile = 8.5
Step-by-step explanation:
- First of all, you need to order the numbers from lowest to greatest: 2 2 3 4 4 6 6 8 9 9
- Then, you will find at the number that sits exactly at the middle of this set of numbers. Because this is a set of numbers that has 10 numbers, you will have to look at the two middle points (4 and 6) and divide them by 2 (essentialy finding the average).
4+6=10, 10/2 = 5 = Mean
- To find the upper and lower quartiles, you basically have to find the medians of the set of numbers that are below and above the central median
- So, for the lower quartile, the set of numebrs is: 2 2 3 4. The median sits between 2 and 3, so we have to find the average of those: 2+3=5, 5/2=2.5
- For the upper quartile, the set of numbers is 6 8 9 9. The median is the average of 8+9. So 8+9=17, 17/2 = 8.5
