I think it’s seventy five
Answer:
1. The growth rate is 2
2. The sample is losing half its mass, so the decay factor is 1/2 or 0.5
Step-by-step explanation:
The growth and decay factor in an exponential function is the number that is being multiplied to the power of x
- It is a growth rate when that number is greater than 1
- It is a decay rate when the number is less than 1
- If it's 1 then it's not growing or decaying
- If it's 0 you will have an answer of 0
I don't know it's so difficult
Answer: (0.8115, 0.8645)
Step-by-step explanation:
Let p be the proportion of people who leave one space after a period.
Given: Sample size : n= 525
Number of people responded that they leave one space. =440
i.e. sample proportion: 
z-score for 90% confidence level : 1.645
Formula to find the confidence interval :


Hence, a 90% confidence interval for the proportion of people who leave one space after a period: (0.8115, 0.8645)
