Answer:
1485120
Step-by-step explanation:
Since the order of arrangement does not matter, we use combination :
Recall :
nCr = n! ÷ (n-r)!r!
For administrator : 1 out of 5 :
5C1 = 5! ÷ (5-1)!1!
For faculty members : 3 out of 14 :
14C3 = 14! ÷ (14 - 3)!3!
For students : 3 out of 18 :
18C3 = 18! ÷ (18 - 3)!3!
5C1 * 14C3 * 18C3 = 1485120
Answer:
117 degrees
Step-by-step explanation:
The sum of all angles in a triangle equals 180 degrees. If you know two of the degrees, you can subtract them to get the third.
180 degrees - 27 degrees - 36 degrees = 117 degrees
Answer:
0.15y
Step-by-step explanation:
0.2*0.75*y = 0.15y
I'm pretty sure y is 25.5, since you multiply 4 by 4.25 to get 17, so 6 x 4.25 is 25.5
