Using a Laplace expansion along the first column, we have
The determinant of a 2x2 matrix is trivial,
So we have
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.
Answer:
x=-1
Step-by-step explanation:
hello :
3x+9-7x=2(x+6)
3x+9-7x=2x+12
3x-2x-7x=12-9
-6x = 6
x=6/-6 = -1
This is the concept of scale factors, if figure 1 was dilated to figure 2 the scale factor was given by;
scale factor=[length of figure 2]/[length of figure 1]
length of figure 1=18
length of figure 2 =3
thus;
The scale factor of the dilation will be:
3/18
=1/6
