Answer:
175(130)^t) < 1200
Step-by-step explanation:
The occupancy is 1200 so it must me less than 1200 (<1200)
the number of people in at any time is 100% of the people in or 1.00
and it increases by 30% or 0.30 (1.30)
And it starts with 175 people (1.75)
so
start people / How its increases / to the power of t / less than capacity
175 (1.30) 
< 1200
17/10 is what ur looking for

<span>A medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 18 minutes. How large a sample should she take to estimate the mean time to within 4 minutes with 97% confidence?
-----
n = [z*s/E]^2
---
n = [2.17*18/4]^2 = 96 when rounded up
