The number of social media post of Noami has a greater spread when compared to that of Amir.
<h3 /><h3>What is the range and intequartile range of the social media posts?</h3>
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
- The range of Amir's social media posts = 19 - 15 = 4
- The range of Noami's social media posts = 10 - 0 = 10
The inter quartile range is the difference between the third quartile and the first quartile of a data set.
IQR = Q3 - Q1
The IQR of Amir's social media posts: 7
The IQR of Naomi's social media posts = 10

Answer:
C multiply the first equation by 3
Step-by-step explanation:
3x-y =5
2x+3y = 10
We want to eliminate y
Since the first equation has a negative 1y and the second equation has 3y
I would multiply the first equation by 3 and then the y's cancel
3(3x-y =5)
9x -3y = 15
2x+3y = 10
------------------
11x = 25
