Answer:
a³ - a² - 3a+ 6
Step-by-step explanation:
we are asked by how much does (a³-2a) exceed (a²+a-6)
in other words, we are being asked to find the difference between the 2 terms above.
Mathematically we are asked to find:
(a³-2a) - (a²+a-6) (expand parentheses by distribution property)
=(a³-2a - a²- a + 6)
= a³ - a² - 3a+ 6 (answer)
Answer:
a)
Students who are skipping class cannot be sampled
Students Who are on a school trip cannot be sampled
Students who are out sick cannot be sample
b)
Dropouts cannot be sampled
Home-schooled students cannot be sampled
Step-by-step explanation:
a)
The population members that might be omitted from sampling frame consists of students who are skipping class, students on a trip and students that are sick because population includes all the students in statistics class.
The dropouts are already out of population and home-schooled are also not a part of population and we are only interested in statistics class so, the students who are not taking the statistics class cannot represent the under coverage of sampling frame
b)
The under coverage sampling frame in this scenario represents by dropouts and home-schooled students because we are taking sampling frame by student roaster of high school.
The student who sick,on a trip and skip class can be found in student roaster so, they don't represent under coverage of sampling frame.
