Answer:
80
Step-by-step explanation:
A certain company employs 6 senior officers and 4 junior officers. If a committee is to be created that is made up of 3 sr officers and 1 jr officer, how many different committees are possible?
8
24
58
80*
210
I initially got this one wrong, but after I saw the answer which is 80, I was able to solve it. But im not sure if this is the proper way of solving it, or if someone can suggest a more efficient way of solving it?
This is what I did, which was wrong:
Sr Officers + Jr Officers
(6!/3! 3! = 20) + (4!/3! = 4) = 24
It seems like the correct answer is:
Sr Officers X Jr Officers
(6!/3! 3! = 20) x (4!/3! = 4) = 80
If this is the most efficient way of solving, when do you know when to add them as opposed to multiplying them in this case?
Answer:
First derivative the equation
39x²-318x-412=0
then use the quadratic formula
then x = 9.29 or x = -1.14
If the perimeter is 90 feet and on side is 26 feet then the width of the playground is 38 feet
Yea I agree with both of them as 1/4 and 25/100 is the same as 25%. As you can put 25 percent in a fraction form as they both used for example 1/4,2/8 or even 25/100.
Answer:
Step-by-step explanation:
1 Simplify brackets.
-3,9=-3,9,-3,-5−3,9=−3,9,−3,−5
2 Since -3,9=-3,9,-3,-5−3,9=−3,9,−3,−5 is false, there is no solution.
No Solution
Done
