In constructing an inequality, you need to know the following:
1. What don't we know? How many songs can be bought? So, let x be the numbers of songs.
2. What do we know? Each songs costs $2 plus a fee for using the artist's site of $5.
3. Is there more than 1 possible solution? Yes, because there is enough money left if she only bought 1 song.
The meaning of no more than $40 means it must not exceed $40, $40 or less, or only $40.
So, song + fee can't be more than $40 and song + fee could equal to $40.
Therefore, song + fee for using an artist's site less than or equal to $40.
Final Answer: 2x+5 <= 40
nCr(20, 2) = 190 ways of selecting 2 from 20
nCr(10, 1) = 10 ways of selecting 1 from 10
To find the over all probability of winning,
Calculate the Harmonic Mean (19) and divide by 2
Equivalent to
1/ (1//190 + 1/10) =9.5
So the probability is 1/9.5 = 2/19.
Answer:
I would say, " Know the reason behind what you are doing when calculating a problem. If someone asks you how you solved that problem, you should be able to quickly and clearly explain to them what you are doing. If not, you are doing something wrong. "
