To solve for this question using the formula, plug in your known values where r is the rate (2.3%), P is the principal amount ($35,000), and t is the time in years. However, keep in mind when you plug the percent rate into the formula, you must first convert it to a decimal which would be 0.023. Now that you have this, plug your values into the equation:
A=35,000(1+0.023)^20
When simplified, you should get a result of about $55,154.47 or the second answer choice.
Answer:
The margin of error for a 95% confidence interval estimate for the population mean using the Student's t-distribution is of 6.22 ounces.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 23 - 1 = 22
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 22 degrees of freedom(y-axis) and a confidence level of
. So we have T = 2.0739
The margin of error is:
M = T*s
In which s is the standard deviation of the sample.
In this question:
s = 3.
Then
M = 2.0739*3 = 6.22
The margin of error for a 95% confidence interval estimate for the population mean using the Student's t-distribution is of 6.22 ounces.
Answer:
19.3
Step-by-step explanation:
Yes. This is because 19/4 as a mixed number is 4 3/4. 4 3/4 < 5. It might be a tight fit but she has enough room
