Jameson asks 10 friends to name their favorite bird. He makes the following percent bar graph to show the results:
A bar graph illustration shows a horizontal axis with the terms robin, hawk, and flamingo. The vertical axis is labeled Percentage and ranges from 0 to 50 in increments of 10. On the horizontal axis, the bar value for robin is 30 percent. The value for hawk is 50 percent. The value for flamingo is 20 percent.
How many of Jameson’s friends named robin as their favorite bird?(1 point)

Teranda is a medical researcher. She asks 25 subjects their blood type and makes the following relative frequency table to show the results:
Blood Type Frequency Relative Frequency
A 10 1025 = ?%
B 4 425 = ?%
AB 2 225 = ?%
O 9 925 = ?%
Then, Teranda makes a percent bar graph to summarize her results. How far up do the bars for Type A and Type B go?

To find the percentage for each type, you need to divide the frequency of that type by the total number of subjects (25) and then multiply by 100.
For Type A:
Frequency of Type A = 10
Relative Frequency of Type A = 10/25 = 0.40 = 40%
For Type B:
Frequency of Type B = 4
Relative Frequency of Type B = 4/25 = 0.16 = 16%
Therefore,
Type A = 40%, Type B = 16%
Use the table to answer the question.
Language Frequency Relative Frequency
German 3 325= ?%
Mandarin 5 525= ?%
Spanish 17 1725= ?%

To find the percentages for each language, you need to divide the frequency of that language by the total number of friends (25) and then multiply by 100.
For German:
Frequency of German = 3
Relative Frequency of German = 3/25 = 0.12 = 12%
For Mandarin:
Frequency of Mandarin = 5
Relative Frequency of Mandarin = 5/25 = 0.20 = 20%
For Spanish:
Frequency of Spanish = 17
Relative Frequency of Spanish = 17/25 = 0.68 = 68%
Therefore,
German bar = 12%, Mandarin bar = 20%, and Spanish bar = 68%

A bar graph illustration shows a horizontal axis with the terms green, pink, and purple. The vertical axis is labeled Percentage and ranges from 0 to 50 in increments of 10. On the horizontal axis, the bar value for green is 20 percent, the bar value for pink is 30 percent, and the bar value for purple is 50 percent.
Kamla asks 20 neighbors to name their favorite color. He makes the percent bar graph to describe the distribution of the dataset. How many of Kamla’s neighbors chose pink as their favorite color?
(1 point)

Based on the given information from the bar graph:
- Green: 20%
- Pink: 30%
- Purple: 50%
Since we are looking for the number of neighbors that chose pink as their favorite color, we can see that the bar value for pink is 30%. This means that 30% of the 20 neighbors chose pink.
Therefore, to find the number of neighbors that chose pink, you would calculate:
Number of neighbors choosing pink = 30% of 20
Number of neighbors choosing pink = 0.30 * 20 = 6
Therefore, 6 of Kamla's neighbors chose pink as their favorite color.
