A shipment to a warehouse consists of 2,750 MP3 players. The manager chooses a random sample of 50

Juli2301 [7.4K]

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.

$\bf{1) \ x^4-61x^2+900=0 }$

Applying the factorization method, for example:

$\bf{ 0=(x^2)^2-61(x^2)+900=(x^2-36)(x^2-25)}$

$\bf{\\ &=(x+6)(x-6)(x+5)(x-5); }$

$\bf{ x_1=6 \quad x_2=-6 \quad \ \ \ x_3=5 \quad x_4=5 }$

$\bf{2) \ x^4-25x^2+144=0 }$

Applying the factorization method:

$\bf{0&=(x^2)^2-25(x^2)+144=(x^2-16)(x^2-9) }$

$\bf{ =(x-4)(x+4)(x-3)(x+3); }$

$\bf{ x_1=4 \quad x_2=-4 \quad x_3=3 \quad x_4=-3 }$

Answer:

t = $\frac{D-M}{Mr}$

Step-by-step explanation:

Given

D = M + Mrt ( subtract M from both sides )

D - M = Mrt ( divide both sides by Mr )

$\frac{D-M}{Mr}$ = t
