MP3 players in the shipment which are likely to be defective is 330.
Step-by-step explanation:
• Probability is event of an occurrence which is uncertain.
• Probability always lies between 0 to 1.
• The sample of 50 MP3 has 6 defective, to solve it has to be converted.
• Convert percentage in 100 multiply numerator and denominator by 2.
• Result is 6/50 converted to 12/100, bring it to 0.12%.
• 12% is defected in 100% of sample.
• It is found here that 2750 is the population and 12% of 2750.
• 2750 * 0.12 = 330, defective pieces in 2750.
• There are three types of Classical,Empirical or Experimental.
• Classical are ‘n’ number of events find the probability occurrence.
• Empirical or experimental is purely based on events.

Arccos is the same thing as inverse cosine which is used when you are looking for an angle measure. Make sure your calculator is in degree mode. Hit 2nd button then cos and you will see this on your screen:
and it is following the parenthesis there that you will enter your decimal. The inverse cosine of .67 is an angle measure of 47.93°
Answer:

Step-by-step explanation:
let s = total songs sung at the concert
If it took 1/8 to sing one song, it would take 1/8 x s hours to sing s songs
= 
1/8 s = 5/4
Divide both sides of the equation by 8
s = 5/4 x 8
s = 10
Answer:
<u>D. Taylor correctly found the distance between –4 and 45, but this number represents the total distance the team moved in both directions, not the team’s total gain.</u>
Step-by-step explanation:
The team only ended up gaining the 45 yards on the second play and had gained -4 on the first play. 45-4≠49, but the total distance between -4 and 45 is 49.
