Answer:
n = 20 or n = -2
Step-by-step explanation:
Solve for n over the real numbers:
n^2 = 18 n + 40
Subtract 18 n + 40 from both sides:
n^2 - 18 n - 40 = 0
The left hand side factors into a product with two terms:
(n - 20) (n + 2) = 0
Split into two equations:
n - 20 = 0 or n + 2 = 0
Add 20 to both sides:
n = 20 or n + 2 = 0
Subtract 2 from both sides:
Answer: n = 20 or n = -2

You would be 12. 6*2=12 then divide by 200
Answer:
a) find the attached graph
b) find the attachment no 4 and 5
c)
Step-by-step explanation:
a) A trend pattern exist if the time series plot gradually shifts to higher or lower values over a long period of time
find the attached graph
b) Liner Trend Equation
Where 
is the linear trend forecast in period t , 
is the intercept of the linear trend time, 
is the slope of the linear trend line, t is the time period
now computing the slope and intercept
<u>formula is attached ( 3 no attachment)</u>
is the value of the time series in period t, n is the number of time periods
Y(bar) is the average value and t(bar) is the average value of t
<u><em>due to unavailability of equation in math-script i attached the calculation part of this question( 4th and 5th no attachment)</em></u>
thus the linear trend equation is 
(1)
