So the second question asks about the perimeter of a rectangular pool and the answer for that is W=87m.
I don’t know about the first question sorry but I’ll try figuring it out.
Answer:
Neither
Step-by-step explanation:
Check if it's arithmetic:
-8, -3, 6, 11, -22
+5 +6 +5 -33
Nope
Check if geometric:
-8, -3, 6, 11, -22
*3/8 *-2 *11/6 *-2
Nope
So it's neither
To answer this problem, the utilization of the provided formula is of utmost importance.
The formula to be used would be for the combination with no repetition since it is what is asked and possibly happens when involving the products mentioned in the problem. The formula would be
n! where in
------------- n = number of things to choose from
(n - r)! r! r = number of things needed to form
the symbol ! is called a factorial function which replaces the sequence of multiplying a number in a descending order.
lets substitute and solve
13!
--------------
(13 - 6)! 6!
13!
-------------
(7!) 6!
6,227,020,800
-------------------
5,040 x 720
6,227,020,800
-------------------
3,628,800
1,716
The answer would be 1,716.
