Answer:
462ways
Step-by-step explanation:
This Is a combination problem, we we are expected to determine the number of possible ways of selecting the numbers of staffs for a business trip
C(n, r) were n= 11
r=5
C(n, r) = n!/(n-r)! r!
C(n, r) = 11!/(11-5)! 5!
C(n, r) = 11!/(6)! 5!
C(n, r) = 11*10*9*8*7*6!/(6)! 5*4*3*2*1
C(n, r) = 11*10*9*8*7/5*4*3*2*1
C(n, r) = 55440/120
C(n, r) = 462
The number of possible ways is 462
40 because the way it shaped is the answer really
Answer:
box 1: monomial
box 2: binomial
Step-by-step explanation:
reasoning: Box 1’s volume is modeled by a monomial times a monomial, so it will be a monomial.
Box 2’s volume is modeled by a monomial times a binomial, so it will be a binomial.
Answer:
2
Step-by-step explanation:
X-2y=-12
x+6y=20
we can cancel x's
multiply first equation by -1 and add to 2nd equation
-x+2y=12
<u>x+6y=20 +</u>
0x+8y=32
8y=32
divide both sides by 8
y=4
sub back
x-2y=-12
x-2(4)=-12
x-8=-12
add 12 both sides
x=-4
(x,y)
(-4,4)
