Question

the two - way frequency table shows data on students who use the social media platforms: snapchat and instagram. use the table to answer the following question: how many students use instagram and do not use snapchat?

Explanation:

Step1: Recall two - way table concept

In a two - way frequency table, to find the number of students who use Instagram and do not use Snapchat, we need to use the row - column relationships. The total number of students is 64. The number of students who use Snapchat is 16 and 7 of them use Instagram. The number of students who do not use Instagram is 36 and 27 of them do not use Snapchat.

Step2: Calculate the value

We know that the total number of students who do not use Snapchat is \(64 - 16=48\). Let \(x\) be the number of students who use Instagram and do not use Snapchat. We also know that the number of students who do not use Instagram and do not use Snapchat is 27. So \(x=48 - 27\).
\(x = 21\)

Answer:

21
