Suppose you just purchased a digital music player and have put 15 tracks on it. After listening to them you decide that you like
Lilit [14]
The given case is an example of permutation problem because the order is important given that you should like the first two songs. The sample space is calculated through the equation, 
                                       15P2 = 210
Then, there are 3 songs that you liked, the probability of picking 2 out of them is,
                                         3P2 = 6
Dividing the latter by the earlier result will give us an answer of 1/35.

Suppose that news spreads through a city of fixed size of 700000 people at a time rate proportional to the number of people who
Gnoma [55]

Answer:

y'(t) = k(700,000-y(t))  k>0 is the constant of proportionality

y(0) =0

Step-by-step explanation:

(a.) Formulate a differential equation and initial condition for y(t) = the number of people who have heard the news t days after it has happened.

If we suppose that news spreads through a city of fixed size of 700,000 people at a time rate proportional to the number of people who have not heard the news that means  

<em>dy/dt = k(700,000-y(t)) </em>where k is some constant of proportionality.

Since no one has heard the news at first, we have

<em>y(0) = 0 (initial condition) </em>

We can then state the initial value problem as

y'(t) = k(700,000-y(t))

y(0) =0
