Question

students were surveyed to determine their favorite types of animals. the bar graph shows the number of students who selected each type of animal. what percentage of the students surveyed selected \bird\ as their favorite type of animal? a 20% b 5% c 6% d 80%

Explanation:

Step1: Find total number of students

Count the number of students for each animal type: 8 (Cat) + 9 (Dog)+ 6 (Bird)+ 4 (Lizard)+ 2 (Fish)=29 students.

Step2: Calculate the percentage for bird - loving students

The number of students who selected bird is 6. The formula for percentage is $\frac{\text{Number of bird - loving students}}{\text{Total number of students}}\times100\%$. So, $\frac{6}{29}\times 100\% \approx 20.69\% \approx 20\%$.

Answer:

A. 20%
