From what you said the choices go up by 3 every time in different combinations . Its at least 36 or more combinations .
i did my best guess from the choice .. hope it helps
Answer: 60.5
Step-by-step explanation:
The forecast for the next period using the simple exponential smoothing method is given by:
, where D= actual demand for the recent period,
smoothing factor, F= forecast for the recent period .
Given: D= 64,
, F= 59
The forecast for the next period = 

Hence, the forecast for the next period = 60.5
It is a equilateral
Equilateral triangles are triangles that have measurements of the same lengths on all sides
Here, number of periods (years), n=5
Annual interest rate, i=0.05 (compounded yearly)
Present value/deposit, P=100
Future value of deposit = P(1+i)^n=100(1.05^5)=127.63 (to the nearest cent)
Answer: After 5 annual interest payments, Bob will have 127.63 in his account.
