Digital music distribution provides an opportunity for everyone to get their music heard. In order to get on a service like iTun
Fiesta28 [93]

Based on the charge to the artist and the amount the streaming services pay, the following are true:

  1. -50.
  2. 5.
  3. y = 5x - 50
  4. .
  5. 10,000 streams.
  6. 190,010,000 streams

<h3>What model can be derived for the streaming data?</h3>

The y-intercept would be the amount that the artist has before they start making any money. In this case that amount is -$50 because they will owe the distributor.

The slope is the change per unit which is $5.00 here.

The formula is therefore:

y = mx + b

y = Slope × x + b

y = 5 × x + (-50)

y = 5x - 50

The number of streams to pay off the distributor is when the profit is $0:

0 = 5x - 50

50 = 5x

x = 10 units

Number of streams:

= 10 units x 1,000

= 10,000 streams

To make a profit of $950,000, the units are:

950,000 = 5x - 50

5x = 950,000 + 50

x = (950,000 + 50) / 5

= 190,010 units

Number of streams is:

= 190,010 x 1,000

= 190,010,000 streams

pshichka [43]

The survey was intended for Bill's middle school during the summer. The

survey was administered to students of other schools on a Saturday.

  • The type of error is the <u>selection bias error</u>.

Reasons:

The type of error made is a non sampling error, given that the target of the

study is the number of times in a week students at his middle school

attend the beach during the summer.

The errors are; Selection bias error.

  • The given that the students survey are not from his middle school.
  • The survey was carried out once on a Saturday, where the target was during the summer.

The selection bias error is a type error that is due to the researcher

chooses what to study, such that the participant have common

characteristics rather than being random.
