Answer: IQR = 16
Step-by-step explanation:
The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.
percentage : 25 50 75
score : 64 74 80
Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.
If the number of observations is odd, then the median is observation
term
If the number of observations is even, then the median is observation and observations.
given n=3, middle term is '74'
In this given data the median is (M) = 74
Interquartile range IQR = median of upper half-median of lower half
= 80-64
= 16
IQR = 16

General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(10x³ - 3x - 5) - (7x² + 4x - 9)
<u>Step 2: Simplify</u>
- Distribute negative: 10x³ - 3x - 5 - 7x² - 4x + 9
- Combine like terms (x): 10x³ - 7x² - 7x - 5 + 9
- Combine like terms (Z): 10x³ - 7x² - 7x + 4
