Answer:
This is a stratified random sample because a separate random sample is selected from each class
Explanation:
Stratified random sampling is an appropriate method when the population consists of mixed characteristics and you would like to ensure that every characteristic is proportionally represented in the sample. In this example, the population is the students from Central High School and the mixed characteristics are the different classes such as Freshman students, Sophomore students, Juniors and Seniors.
After the population is divided into subgroups based on characteristics, from the overall proportion of the population, you calculate how many people should be sampled in each subgroup. Random or systematic sampling can then be used to select a sample from each subgroup.
Answer:
27.29 months
Explanation:
Using Present Value Annuity (PV A):
PV A = c x (1- 1/(1+r)^t)/r
c = Monthly repayment
t = time it will take to pay off
r = rate of interest per month
$ 11,500 = $500 x (1 – 1 / (1+0.0125)^t / 0.0125
When you solve this problem you get:
1/(1+0.0125)t = 1 – (($11,500)(0.0125) / ($500))
1/1.0125^t = 0.7125
1.0125^t = 1/0.7125
1.0125^t = 1.4035
t = In 1.4035 / In 1.0125
t = 27.29 months
Answer:
$273.96
Explanation:
The balance will be the future value of $209, at 7% for four years.
The formula for calculating the future value is as below.
FV = PV × (1+r)^n
Where PV is the present value, $209
r= is the interest rate 7% or 0.07
n= 4 years
FV = $209 x ( 1+ 0.07) ^4
Fv =$209 x 1. 310
Fv = 273.9563
Fv= 273.96
The statement that as a franchisee, Liam is guaranteed the right to retain all of his franchise's revenues and profits is false.
Franchisees usually pay a royalty to the franchisor - the party that gets <span>the right to market a product or service using the trademark or trade name of another business (franchisee)</span>. The royalty can be a share of the franchisee's revenues or a share of the franchisee's profits.
