Question

victoria collected data about the number of cats that each of her classmates had. the results are shown in the dot plot below. number of cats 1. count the number of dots. how many students are in victorias class? 2. how many students have two cats or less? 3. what number of cats is the mode for the class? 4. what percent of students have at least 3 cats? number with at least 3 cats / total number of students = _ = _ ÷ _ = _ → multiply by 100 percent = ___

Explanation:

Step1: Count the total number of dots

Count each dot in the dot - plot. There are \(4 + 6+4 + 2+1+1+1 = 20\) dots.

Step2: Find students with two cats or less

Add the number of dots for \(0\), \(1\), and \(2\) cats. \(4 + 6+4=14\)

Step3: Determine the mode

The mode is the value with the most dots. The number of cats with the most dots is \(1\) (6 dots)

Step4: Calculate the percentage of students with at least 3 cats

The number of students with at least 3 cats is \(2 + 1+1+1=5\). The formula for percentage is \(\frac{\text{Number with at least 3 cats}}{\text{Total number of students}}\times100\). So \(\frac{5}{20}\times100 = 25\%\)

Answer:

1. \(20\)
2. \(14\)
3. \(1\)
4. \(\frac{5}{20}=5\div20 = 0.25\), Percent \(=25\%\)
