Answer:
28 month (approx)
Explanation:
Given
Present value = $470
Monthly Payment = $20
Interest Rate = 15% annual = 15% / 12 = 1.25% monthly
=0.0125
<h3>
![Present Value = PMT [\frac{1-(1+i)^{-n}}{i}] \\470 = 20 [\frac{1-(1+0.0125)^{-n}}{0.0125}]\\470/20 = [\frac{1-(1+0.0125)^{-n}}{0.0125}]\\23.5 \times 0.0125 =1-(1+0.0125)^{-n}\\1-0.29375= (1+0.0125)^{-n}\\0.70625 = (1+0.0125)^{-n}\\0.70625 =(1.0125)^{-n}\\0.70625= \frac{1}{(1.0125)^{n}}\\(1.0125)^{n}=1.4159292\\n=28(approx)](https://tex.z-dn.net/?f=Present%20Value%20%3D%20PMT%20%5B%5Cfrac%7B1-%281%2Bi%29%5E%7B-n%7D%7D%7Bi%7D%5D%20%5C%5C470%20%3D%2020%20%5B%5Cfrac%7B1-%281%2B0.0125%29%5E%7B-n%7D%7D%7B0.0125%7D%5D%5C%5C470%2F20%20%3D%20%5B%5Cfrac%7B1-%281%2B0.0125%29%5E%7B-n%7D%7D%7B0.0125%7D%5D%5C%5C23.5%20%5Ctimes%200.0125%20%3D1-%281%2B0.0125%29%5E%7B-n%7D%5C%5C1-0.29375%3D%20%281%2B0.0125%29%5E%7B-n%7D%5C%5C0.70625%20%3D%20%281%2B0.0125%29%5E%7B-n%7D%5C%5C0.70625%20%3D%281.0125%29%5E%7B-n%7D%5C%5C0.70625%3D%20%5Cfrac%7B1%7D%7B%281.0125%29%5E%7Bn%7D%7D%5C%5C%281.0125%29%5E%7Bn%7D%3D1.4159292%5C%5Cn%3D28%28approx%29)

Answer:
The correct answer is binary variables.
Explanation:
A binary variable is one that can only have two possible values. They generally fulfill two essential characteristics:
1. They are made up of two exhausting values, which indicates that there is no other possibility of response. For example, a person is female or male.
2. Both values of the variable are exclusive, that is, it is not possible that both responses can be given, only one. In the same example above, a customer cannot be a woman and a man at the same time.
