Given:
- The typical balance on Lucy's credit card is $650.
- The interest rate (APR) on her credit card is 18%.
Question:
How much in interest would you expect Lucy to be charged in a typical month?
The Process:
This problem includes the type of determining simple interest.
where,
- I = simple interest
- P = principal (initial amount)
- r = annual interest rate
- t = time (in years)
This time we will find out how much in interest we would expect to be charged in a typical month.
The data is as follows:
- P = 650
- r = 18% or
or 0.18
- t =
year (one month)
Let us calculate how much in interest we would expect to be charged in a typical month.
Thus the amount of interest we would expect Lucy to be charged in a typical month is $ 9.75.

Notes
We must be able to distinguish between simple and compound interest. Please learn about this in the link attached below.

Answer:
Answer = √(0.301 × 0.699 / 83) ≈ 0.050
A 68 percent confidence interval for the proportion of persons who work less than 40 hours per week is (0.251, 0.351), or equivalently (25.1%, 35.1%)
Step-by-step explanation:
√(0.301 × 0.699 / 83) ≈ 0.050
We have a large sample size of n = 83 respondents. Let p be the true proportion of persons who work less than 40 hours per week. A point estimate of p is because about 30.1 percent of the sample work less than 40 hours per week. We can estimate the standard deviation of as . A confidence interval is given by , then, a 68% confidence interval is , i.e., , i.e., (0.251, 0.351). is the value that satisfies that there is an area of 0.16 above this and under the standard normal curve.The standard error for a proportion is √(pq/n), where q=1−p.
Hope this answer helps you :)
