Since the order matters Person A and B can be chosen as AB (A pres B vice pres) or BA (B president A Vice president)
When the order matters we are talking about permutations. How many permutations of 11 taken 2 at a time are there.
It can be written like this 11nPr 2
It means start at 11 and multiply by the next lower number
11 x 10 = 110 ways they can choose.
Extension of the concept:
If there had been three positions President, Vice President, and Treasurer
then it would be 11nPr3 or 11 x 10 x 9
Once again the answer to your problem is 110.

Answer:
Step-by-step explanation:
When you multiply two terms with same base, add the exponents.
Example: x*x² = x* x*x = x³
In short, x*x² = x¹⁺² = x³

A = # of adults = 3
s = # of students = 5
9(3) + 6(5) =
27 + 30 =
57
Let
A---------> the temperature in <span>New York City
B---------> </span>the temperature in <span>Houston
we know that
A=33</span>°
B=85°
[<span>the increase in temperature from New York to Houston]=B-A
</span>
[the increase in temperature from New York to Houston]=85°-33°---> 52°
the answer is
52°
