<u>Answer:</u>
The correct answer option is B. c = 25 + 2m.
<u>Step-by-step explanation:</u>
We are given that a movie rental club charges a one time fee of $25 to join and $2 for every movie rented.
We are to determine whether which of the given equations in the answer options represent how much you would spend to join the club and rent movies for a year.
The correct answer option is B. c = 25 + 2m.
One time charges = 25 plus $2 multiplied by the number of movies rented.

Step-by-step explanation: she only has 3 because of herself
Answer:
<em>Lisa borrowed $8,500</em>
Step-by-step explanation:
<u>Simple Interest
</u>
Occurs when the interest is calculated on the original principal of a loan only.
Unlike compound interest where the interest earned in the compounding periods is added to the old principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=Prt
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Lisa took out a loan for t=5 months and was charged simple interest at an annual rate of r=4.8% = 0.048. She paid interest for I=$170.
We need to convert the time to years (there are 12 months per year):
t = 5 /12 years.
The formula must be solved for P:
Substituting:
Lisa borrowed $8,500
Answer:
g(x) = a(x − h)2 + k, where a ≠ 0.
Step-by-step explanation:
The parent function of the quadratic family is f(x) = x2. A transformation of the graph of the parent function is represented by the function g(x) = a(x − h)2 + k, where a ≠ 0.
Answer: Sample statistics are used to make inferences about population parameters.
Step-by-step explanation:
A number which describes a population is called a parameter, such as a proportion or percentage.
A statistic is a number which may be calculated from the data observed in a random sample without demanding the use of any unknown parameters.
The mean and variance of a population are population parameters.
Thus, fourth statement is the right answer "Sample statistics are used to make inferences about population parameters."
