Answer:
124(cm)^2
Step-by-step explanation:
total surface area of a cuboid=
length=7cm
Breadth=5cm
Height=4cm
2{(2*7)+(5*4)+(4*7)}
2{14+20+28}
2*62
124(cm)^2
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.
There should be 60 possible outcomes.
Answer:
3yz(y+4z-6)
Step-by-step explanation:
Pi*radius squared= area of a circle
3.14*2^2=12.56yd^2
pi*diameter=circumference
3.14*4=12.56yd
area of surface around the cylinder=circumference*height
12.56*6=75.36yd^2
area of surface around the cylinder+ (area of circle*2)= surface area
75.36+(12.56*2)=100.48
the answer should by 100.48 yards squared
hope this helps
