Ответ:
.3(24.40a + 14.50c)
24.40 = cost of adult ticket
14.50 = cost of child ticket
a = # of adult tickets sold
c = # of child tickets sold
.3 * 24.40a + .3 * 14.50c
7.32a + 4.35c
Ответ:
Yes, it will be a biased study.
Step-by-step explanation:
Given is that -
Pollsters take a survey of people at a ball game to collect and analyze data about favorite leisure activities of star city’s residents.
This study will be biased and it will produce biased results.
Firstly, few people at ball game do not represent the whole population of the city and it is not necessary that all the people at ball park will respond to the question in the survey.
