Assoli18 [71]

Question:

You are interested in estimating the the mean age of the citizens living in your community. In order to do this, you plan on constructing a confidence interval; however, you are not sure how many citizens should be included in the sample. If you want your sample estimate to be within 5 years of the actual mean with a confidence level of 97% , how many citizens should be included in your sample? Assume that the standard deviation of the ages of all the citizens in this community is 18 years.

Answer:

61.03

Step-by-step explanation:

Given:

Standard deviation = 18

Sample estimate = 5

Confidence level = 97%

Required:

Find sample size, n.

First find the Z value. Using zscore table

Z-value at a confidence level of 97% = 2.17

To find the sample size, use the formula below:

$n = (Z * \frac{\sigma}{E})^2$

$n = ( 2.17 * \frac{18}{5})^2$

$n = (2.17 * 3.6)^2$

$n = (7.812)^2$

$n = 61.03$

Sample size = 61.03

petes unpaid credit card balance is 3529.30. His apr is 18.6% and he made one new transaction for 148. what is his new balance

My name is Ann [436]

<span>Previous balance = 3529.30
APR = 18.6%, thus monthly interest rate = 18.6 / 12 = 1.55%
Previous balance + interest = 3529.30(1 + 0.0155) = 3584.00
New balance after transaction = 3584.00 + 148 = 3732.00</span>

Which equation represents the situation Please help me

Virty [35]

100 dollars should be a one time fee so that has to be added to the equation, and since it is a one time fee it should not have a variable next to it.

It also says that you have to pay 720 dollars per month, so it has to have a variable next to it to show the number of months that she needs to pay that amount of money.

The answer should be D.

y= 720x +100
