Answer:
A sample, or p hat, is representative when the sample closely remebles the population, which are the students in this case. The third and first answer choice would be correct.
Picking lunch period one is wrong because that would overrepresent the students in the first lunch period. Same applies to the first 30 students.
Pick
Answer:
ok, lemme think bout this
Step-by-step explanation:
Answer: 1, 2, 4, or 5
Step-by-step explanation:
The relationship in #3 is a function because all the x values are distinct, that is, none are repeated. (Y values don't matter.)
A function will not repeat any x values so if your goal is for the relationship in #4 to NOT be a function, repeat one of the x values. Any one will work.
The rational root theorem is used to determine the possible roots of a polynomial
The possible roots of g(x) are:
The leading coefficient (p) is given as:
The constant term (q) is given as:
Using rational root theorem, the possible roots are:
The roots of p and q are:
So, we have:
Substitute known values
Divide
Hence, the possible roots of g(x) are:
