Question

the readers of a magazine reported how many winter hats they owned. winter hats dot - plot with x - marks at 0, 1, 2, 3, 4 on the number line labeled number of winter hats (from 0 to 5). how many readers are there in all? \boxed{} readers

Explanation:

Step1: Count readers with 0 hats

From the graph, the number of X's at 0 is 3. So, 3 readers have 0 hats.

Step2: Count readers with 1 hat

The number of X's at 1 is 9. So, 9 readers have 1 hat.

Step3: Count readers with 2 hats

The number of X's at 2 is 7. So, 7 readers have 2 hats.

Step4: Count readers with 3 hats

The number of X's at 3 is 5. So, 5 readers have 3 hats.

Step5: Count readers with 4 hats

The number of X's at 4 is 5. So, 5 readers have 4 hats.

Step6: Sum all counts

To find the total number of readers, we add the number of readers in each category: \(3 + 9 + 7 + 5 + 5\).
First, \(3+9 = 12\), then \(12 + 7 = 19\), then \(19+5 = 24\), then \(24 + 5 = 29\).

Answer:

29
