There are 105 comparisons made with 15 statistically independent scenarios.
According to the statement
we have given value of n is 15.
Then r = 2. so,
we use the formula NcR then
Substitute the values in it then
15c2
we open it according to ncr formula
In this formula we arrange the terms according to the following
NcR formula = n! /r! * (n-r)!
then the terms will arrange in this way.
So,
ncr = 15! / 2! * 13!
After solving the statement some terms will be cancel with each other and remaining terms are
ncr = 15*14/2
ncr = 210/2
ncr = 105
here the value becomes 105.
So, There are 105 comparisons made with 15 statistically independent scenarios.

Answer:
I think it is 8.2
Step-by-step explanation:
Well we have the equation d = r * t
(d stands for distance, r for rate, and t for time)
So, plug in our values:
d = 55 *4
And, d = 220
I can't see the answer choices, but I hope this will help you!! Let me know if you have ANY questions.
The greatest common factor for 21 is 7
For 30 is 15
49 is 7
I’m no totally sure but i think that is right
A square has four even sides and the perimeter is equal to the sum of all of the sides.

So we can evaluate the equation for P and then solve for s.
