Answer:
x=−1 or x=−9
Step-by-step explanation:
x2+11x+10=x+1
Step 1: Subtract x+1 from both sides.
x2+11x+10−(x+1)=x+1−(x+1)
x2+10x+9=0
Step 2: Factor left side of equation.
(x+1)(x+9)=0
Step 3: Set factors equal to 0.
x+1=0 or x+9=0
x=−1 or x=−9
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:
35/100 *80=25
Step-by-step explanation:
Answer:

25/-10 = -2.5
20/-8 = 2.5
10/-4 = 2.5
-5/2 = 2.5
so the answer is -2.5
