Answer: 56% of people in the audience are male.
Step-by-step explanation:
Given : Total people in the audience = 143
Number of females = 63
Number males = (Total people ) - (Number of females )
= 143 -63
= 80
The percent of people in the audience are male = [tex]\dfrac{\text{Number of males}}{\text{Total people}}\times100\%[/tex]
[tex]\dfrac{80}{143}\times100\%=55.94\%\approx56\%[/tex]
Hence, 56% of people in the audience are male.
