a) if the two gloves someone receives might both be for the left hand or right hand.
b) if each sister gets one left and one right.
Soln:
a) So i thought about dissectng the problem first into finding the number of ways in which I could make pairs of gloves:
C(12, 2)
then I asked how many ways could the sets of gloves be assigned amongst the 6 sisters:
<span><span>6!</span><span>6!</span></span>
and taking the product of this would give me the amount of ways this could occur:
= C(12,2) * 6!
then for part b)
using this same idea except:
C(6,1) C(6,1) for the left and right glove each .
the C(6,1)*C(6,1)*6!
Right way to think them through?
Answer:
the additional charge per minute because t represents the number of minutes
Step-by-step explanation:
Steven gained 100 points.
To calculate the gain or lose of any 2 numbers, always do
Final - Initial
So,
-50 - -150
Is like saying
I have negative 50, and I take away negative 150.
Taking away negative numbers is just addition.
-50 + 150 = 100
Answer:
y = 6
Step-by-step explanation:
We need to interpret the question
y varies directly as x
y varies x
To equate it, we need to add a constant K
y = K/x
Using the information we are provided with
y = 9
x = 3/2
insert into
y = Kx
9 = K * 3/2
9 = 3K/ 2
3K = 9 *2
3k = 18
To get K, divide through by 3
3K/3 = 18/3
K = 6
Since we've gotten our K = 6
y = Kx
Using the new information
y = ?
x = 1
K = 6
y = 6* 1
y = 6
The new y = 6 , x =1
