<em>1. How much interest will Sara owe? </em>
<em>She will owe 5,966 dollars</em>
<em></em>
<em>2. How much will the payments be with a seven year agreement?</em>
<em>Sara will pay 21,666 dollars</em>
<h2>
Explanation:</h2>
The simple interest formula is as follows:
First, converting r percent to r a decimal
Solving our equation:
So Sara will owe in interest the following amount of money:
Finally, answering the questions:
<em>1. How much interest will Sara owe? </em>
<em>She will owe 5,966 dollars</em>
<em></em>
<em>2. How much will the payments be with a seven year agreement?</em>
<em>Sara will pay 21,666 dollars</em>

Answer:
C. All of them
Step-by-step explanation:
The base class is the super/parent class of a child class; so a child class inherit from a base class.
When a child class inherit from a base class; it have access to redefine the member function that is declared public. 'public' is an access modifier which means it can be access from outside the class and modified.
Therefore, all the child class which inherit the base class can redefine the member function that are public.
The value of z* should be used to construct a 97 confidence interval of a population mean is 2.17.
<h3>What is confidence interval?</h3>
A degree of uncertainty and certainty in a sample process is measured by confidence intervals. They can choose from a variety of probability limitations, the most frequent becoming a 95% or 99% confidence level.
Some characteristics of confidence interval are-
- Statistical tools, such as the t-test, are used to compute confidence intervals.
- Confidence intervals are used by statisticians to quantify uncertainty in such a sample variable.
- A researcher, for example, may randomly select multiple samples drawn from the same population and compute a confidence interval for every sample to determine how well it might represent the real value of a population variable.
- The generated datasets are all unique; some intervals contain the genuine population parameter while others do not.
Now, according to the question;
The confidence level is given 97%.
Thus, the crucial value of z for a 97% confidence interval is 2.17, as determined by a z score table, which is as follows:
Therefore the obtained probability for the z-score of 2.17 is 0.97.
