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:
$1.65
Step-by-step explanation:
The total purchase can be described by ...
4(2h +1.25) = 18.20 . . . . where h is the price of a hot dog
8h = 13.20 . . . . . . . . . . . subtract 5.00
h = 1.65 . . . . . divide by 8
The price of a hot dog was $1.65.
U have a geometric sequence. To find the common ratio, divide the second term by the first term. 6/12 = 1/2
an = a1 * r^(n-1)
n = term to find = 10
a1 = first term = 12
r = common ratio = 1/2
now we sub
a(10) = 12 * 1/2(10 - 1)
a(10) = 12 * 1/2^9
a(10) = 12 * 1/512
a(10) = 12/512 reduces to 3/128 ,<== ur 10th term
Answer:
Around 11.9
Step-by-step explanation:
5.3n + 7.75 = 70.85
First subtract 7.75 on both sides.
5.3n = 63.1
Then divide both sides by 5.3
n=11.9 (I rounded to the nearest tenth.)
It’s either going to be 26 or 29 but I’m not sure, sorry.
