Answer:
about 63.1%
Step-by-step explanation:
For the first song, it is certain it isn't a duplicate. For the second song, the probability that it is not a duplicate is 4999/5000. The probability the third song is not a duplicate is 4998/5000.
Hence the probability that none of the 100 songs is a duplicate is ...
5000!/4900!/5000^100 ≈ 0.369120
Then the probability that one or more is a duplicate is ...
1 - 0.369120 ≈ 0.630880
1) P=2w +2l
46=2w +14
32=2w
16= w or width
2) A=lw
A=7 x 12
A= 84
3) A= 12 x 21
A= 252
Answer:
D) 2 less than the quotient of x divided by 4
Step-by-step explanation:
Since it's x/4 there has to be a quotient or division involved in the sentence, which eliminates A and B. Since there's a -2, C is eliminated since it doesn't include 2.
Answer:
The answer is y = -1/3x - 1
Step-by-step explanation:
In order to find this we first must note that parallel lines have the same slope. Therefore, since the slope in the original line is -1/3, then we know the slope in our line will be the same. Now we can use point slope form with that slope and the given point to find the equation by solving for y.
y - y1 = m(x - x1)
y + 3 = -1/3(x - 6)
y + 3 = -1/3x + 2
y = -1/3x - 1
