six random samples were taken each year for three years. the table shows the inferred population for each type of fish for each year.\nwhich conclusion is supported by the data from the multiple - year samples? check all that apply.\nthe number of bass increased over time.\nthe number of bass decreased over time.\nthe number of catfish increased over time.\nthe number of catfish remained the same.\nthe fish population decreased over time.\n\n| year | population trout | population catfish | population bass |\n| :---: | :---: | :---: | :---: |\n| 1 | 77 | 57 | 58 |\n| 2 | 83 | 76 | 40 |\n| 3 | 92 | 80 | 31 |
Answer
Explanation:
Step1: Analyze bass population
In year 1, bass population is 58, in year 2 it is 40 and in year 3 it is 31. Since 58>40>31, the number of bass decreased over time.
Step2: Analyze catfish population
In year 1, catfish population is 57, in year 2 it is 76 and in year 3 it is 80. Since 57<76<80, the number of catfish increased over time.
Step3: Analyze total fish population
Total population in year 1: 77 + 57+58 = 192. Total population in year 2: 83 + 76+40 = 199. Total population in year 3: 92+80 + 31=203. Since 192<199<203, the fish population increased over time.
Answer:
- The number of bass decreased over time.
- The number of catfish increased over time.
