hal surveyed all the sixth graders at his school about their favorite animal. the table shows the results
horse 21
bird 35
cat 35
dog 49
Which percentage graph best represents the data
AAAaannndd the bot gets it wrong yet again!
There are 140 animals
21/140 = 15%
So none of the selections works
If the given numbers are supposed to be percentages, then they need to add up to 100, not 140.
To find the percentage graph that best represents the data, we need to calculate the percentage of each animal category out of the total number of sixth graders surveyed.
First, let's find the total number of sixth graders surveyed:
Total number of sixth graders surveyed = 21 (horse) + 35 (bird) + 35 (cat) + 49 (dog) = 140
Now, let's calculate the percentage for each animal category:
Percentage of horse = (Number of students who chose horse / Total number of sixth graders surveyed) * 100
= (21 / 140) * 100
= 15%
Percentage of bird = (Number of students who chose bird / Total number of sixth graders surveyed) * 100
= (35 / 140) * 100
= 25%
Percentage of cat = (Number of students who chose cat / Total number of sixth graders surveyed) * 100
= (35 / 140) * 100
= 25%
Percentage of dog = (Number of students who chose dog / Total number of sixth graders surveyed) * 100
= (49 / 140) * 100
= 35%
Based on these calculations, the percentage graph that best represents the data would have the following percentages:
Horse: 15%
Bird: 25%
Cat: 25%
Dog: 35%
You can create a percentage bar graph or pie chart using these percentages to visually represent the data.
To determine which percentage graph best represents the data, we need to calculate the percentage of students who chose each animal as their favorite.
First, let's find the total number of students surveyed:
Total = 21 (horse) + 35 (bird) + 35 (cat) + 49 (dog) = 140
Now, let's calculate the percentage for each animal by dividing the number of students who chose each animal by the total number of students surveyed and multiplying by 100:
Horse: (21/140) * 100 = 15%
Bird: (35/140) * 100 = 25%
Cat: (35/140) * 100 = 25%
Dog: (49/140) * 100 = 35%
Now, let's compare these percentages to determine the best representation on a percentage graph:
Option 1: Horse - 15%, Bird - 25%, Cat - 25%, Dog - 35%
Option 2: Horse - 35%, Bird - 25%, Cat - 25%, Dog - 15%
Option 3: Horse - 25%, Bird - 25%, Cat - 25%, Dog - 25%
Since the data shows that the highest percentage corresponds to the dog (35%), we can conclude that Option 1, with the horse representing 15% and the dog representing 35%, is the best representation of the data on a percentage graph.
