You are building a Music Player app.
You need to implement the MusicPlayer class, which should hold the track names as Strings in an array. The array is already defined in the given code.
The player should support the following functions:
add: add the given argument track to the tracks array.
show: output all track names in the player on separate lines.
play: start playing the first track by outputting "Playing name" where name is the first track name.
You can add a new item to an array using +=, for example: tracks += track
make sure the answer or the language code is in kotlin

Consider a student who has the choice to buy or not buy a textbook for a course. We’ll model this as a decision problem with one Boolean decision node, B, indicating whether the agent chooses to buy the book, and two Boolean chance nodes, M, indicating whether the student has mastered the material in the book, and P , indicating whether the student passes the course. Of course, there is also a utility node, U. A certain student, Sam, has an additive utility function: 0 for not buying the book and -$100 for buying it; and $2000 for passing the course and 0 for not passing. Sam’s conditional probability estimates are as follows:
P(p|b,m) = 0.9 P(m|b) = 0.9 P (p|b, ¬m) = 0.5 P (m|¬b) = 0.7 P (p|¬b, m) = 0.8 P (p|¬b, ¬m) = 0.3
You might think that P would be independent of B given M, But this course has an open- book final—so having the book helps.

solve the recurrence relation . x(n)=x(n/3)+n for n>1 ,x(1)=1
The solution to the recurrence relation is [tex]x(n) = \frac 12(3n - 1)[/tex]
How to solve the relation?The relation is given as:
x(n) = x(n/3) + n for n > 1
x(1) = 1
Calculate x(3)
x(3) = x(3/3) + 3
This gives
x(3) = x(1) + 3
x(3) = 1 + 3 = 4
Calculate x(9)
x(9) = x(9/3) + 9
This gives
x(9) = x(3) + 9
x(9) = 4 + 9 = 13
So, we have:
x(1) = 1
x(3) = 4
x(9) = 13
The above sequence forms an arithmetic sequence.
An arithmetic sequence is represented as:
x(n) = x(1) + (n - 1) * d
Substitute 9 for n
x(9) = x(1) + (9 - 1) * d
Substitute 13 for x(9) and 1 for x(1)
13 = 1 + (9 - 1) * d
This gives
12 = 8d
Divide by 8
d = 1.5
Substitute d = 1.5 in x(n) = x(1) + (n - 1) * d
x(n) = x(1) + (n - 1) * 1.5
Substitute x(1) = 1
x(n) = 1 + (n - 1) * 1.5
Expand
x(n) = 1 + 1.5n - 1.5
Evaluate the like terms
x(n) = 1.5n - 0.5
Express as fraction
x(n) = 3n/2 - 1/2
Factor out 1/2
[tex]x(n) = \frac 12(3n - 1)[/tex]
Hence, the solution to the recurrence relation is [tex]x(n) = \frac 12(3n - 1)[/tex]

Answer: B. a = 14 and b = 3
Explanation:
Let's work through the expressions one-by-one:
The first 2 lines create 2 varaibles, a and b, with values of 2 and 7, respectively.
The next line assigns a to the product of a and b.
a * b = 2 * 7 = 14, so the new value of a is 14.
The last line assigns the remainder of b divided by the difference of a and 10.
a - 10 is 14 - 10 which is 4.
The value of b is 7 due to the second expression. 7 % 4 is 3 as 4 goes into 7 once with 3 left over. This value of three is assigned to b.
After all the expressions, the values of the variables are as follows: a = 14 and b = 3.
