Answer:
Systematic sample
Step-by-step explanation:
This is a systematic sample because we are told that the student surveyor interviews the first 30 people to leave his school buildings north exit. This implies that it was not randomly generated but chosen at an ordered form of interval which in this case it is the first 30 people. Thus, the population has been zeroed down to the first 30 people.
Y=-2x+4. is what it simplifies too. there is not enough info to solve
The equation is $130 + $31.67x = 500
Subtract 130 from both sides $31.67x = $370
Divide $31.67 from both sides
X=11.68
BUT
you can’t have .68 of a day so the answer is 11 days.
