I could be very wrong, but I believe the answer is C
Answer:

Step-by-step explanation:
Step 1: Add the numbers.
20.25 can also be expressed as
, because
=
=
. So if we add
and 11, we would get 
Step 2: Solve

- Subtract the whole numbers

This means addition. Also, since our denominators are not the same value, we have to find the LCM (Least Common Denominator): What do 2 and 4 have in common that they can divide themselves by? 4. We know this because 2 divided by 4 is 2, and 4 divided by 4 is 1, so they can both divide themselves by 4.

LCM

Therefore, the simplified expression to this is

Answer:
Step-by-step explanation:
Given that Z the set of integers is the universal set and
A is given in set builder form.

To convert this into roster form, we can find solutions for x
When 
i.e. all integers lying between -2.236 and 2.236
The only integers satisfying this conditions are
-2,-1,0,1,2
Hence A in roster form is
A=
The answer is Letter C - 1/2,775
The probability of choosing one of them is 2 out of 75 while the probability of choosing the other one is 1 out of 74. 74 band members, not counting the other person (you or your bother).
Computation:
P = 2 / 75 * 1 / 74
= 0.0266... * 0.01351...
= 1 / 2,775
You can also multiply 75 with 74 to get a total of 5,550 then divide it by 2 students to be selected to get 2,775. Meaning one out of 2,775 possibilities.
