It is given that the line plot below represents the number of letters written to overseas pen pals by the students at the waverly middle school.Each x represents 10 students.

First of all count the number of x in the given line plot.

The total number of x in the line plot is 30. It means the total number of students is

[tex]30x=30\times x=300[/tex]

From the figure it is noticed that there are four x when the number of letters is 6 and three x where the number of letters is 20.

It means total 40 students wrote 6 letters and 30 students wrote 20 letters.

The number of students who wrote more than 6 but less 20 letters are

[tex]300-40-30=230[/tex]

Therefore option C is correct.

Answer:

(C) 230 number of students wrote more than 6 and fewer than 20.

Step-by-step explanation:

It is given that The line plot below represents the number of letters written to overseas pen pals by the students at the waverly middle school and each x represents 10 students.

We have to find the students who wrote more than 6 and fewer than 20 that is let x be those students, then [tex]6<x<20[/tex]=30+20+10+40+10+20+30+20+10+40=230

Thus, 230 number of students wrote more than 6 and fewer than 20.
