Answer: 142506
Step-by-step explanation:
Given : The total number of choices for people in committee = 30
The number of people need to be chosen =5
Since , here order doesn't matter, so we use combination.
The combination of r things taking from n at a time is given by :-
Now, the number of possible combinations of 5 people be chosen from a total of 30 possible people :-
Hence, the committee can be made in 142506 ways.
I disagree. The first one is false. No exponent rules apply if the bases AND the exponents are different.
The second one is true. Bases are the sane so you add exponents. You get 3 to the -5 power. Written with positive exponents it’s 1/3 to the 5.
Answer is b.
Now we going to solve it
To find how many refills he bought
8.95 + 1.50(r) = 26.95
-8.95 = -8.95 1. subtract $8.95 from
———————————- both sides.
1.50(r) = 18.00 2. The $8.95 cancels
——— = ——— out.
1.50 1.50 3. Bring the equation
R = 12 down.
4. Now you divide 1.50
on both sides.
Final answer R= 12
The answer is 0.4722. I hope this helps :)
17.97 17.89 17.16 17.3 If I am correct.
