the data in the figure below represents the number of stars earned by 140 performers in a talent competition. how many performers earned exactly 1 stars? (be careful - compare the question wording to the scale on the graph)
Answer
Explanation:
Step1: Identify percentage for 1 star
From the bar - chart, the percentage of performers who earned 1 star is 15%.
Step2: Calculate number of performers
The total number of performers is $N = 140$. We use the formula: Number of performers with 1 star=Percentage of performers with 1 star×Total number of performers. So, the number of performers with 1 star is $0.15\times140$. $0.15\times140 = 21$
Answer:
21
