syeda maria plz exact solution upload kru,,,,,,,,and tell k trend kaisy find o ga

Trend = Actual - Moving average

thanx shakeel bhae......plz ye b share kr dain k centered average kaisy find krty hn

1st 2 moving average / 2

example:

170.5 + 166 = 336.5

336.5 / 2 = 168.25

Question 1
Find the centered average and trends in the following data

Quarter Actual Moving Average Centered Average Trend
1 198
2 96
3 202 170.5 31.5
4 186 166 168.25 20
5 180 159.25 162.625 20.75
6 69 184.25 171.75 -115.25
7 302 215.25 199.75 86.75
8 310 220.5 217.875 89.5


Question 2:
a) If the five numbers cards 1,2,3,4,5 are put into a box, in how many different
a) ways could you draw one out?
Ans:
= 5 x 4 x 3 x 2 x 1
= 5!
= 120
b) When one of them has been drawn, in how many ways could you
a) draw a second?
Ans:
5 P 2 = 5! / (5 - 2)! = 120/2 = 60
c) Therefore, in how many ways could you draw two numbers?
Ans:
2! = 2 x 1
2! =2
d) What is the meaning of the symbol 5P4?
Ans:
The number of permutations of 5 different things taken 4 at a time.
e) Evaluate 5P4
Ans:
n P r = n! / (n - r)!
5 P 4 = 5! / (5 - 4)!
5 P 4 = 5 x 4 x 3 x 2 x 1 / 1!
5 P 4 = 120

MTH302 GDB Solution

Attachments:

 5 P 2 = 5! / (5 - 2)! = 120/2 = 60  

is there any mistake

please guide me if i am wrong ???????

5-2=3 

3!=3 x 2 x 1 

=6

nd then

i think so this(120/2 = 60) must be

120/6=20

here is my gdb solution
