Hello!
You can separate the shape into two rectangular prisms
prism 1 - 9, 2 ,4
prism 2 - 4, 2, 8
Since the frosting is on the outside of the cake you have to find the surface area
To find the surface area you use the equation
2(wl + hl + hw)
Put in the values you know
2(9 * 2 + 4 * 2 + 9 * 4)
multiply
2(18 + 8 + 36)
Add
2(62) = 124
Now you find the surface area of the second prism
2(4 * 2 + 2 * 8 + 4 * 8)
Multiply
2( 8 + 16 + 32)
Add
2(56) = 112
Now add the two surface areas to get the surface area of the whole shape
112 + 124 = 236
The answer is 236in squared
Hope this helps!
Answer:
D) All three have the same correlation coefficient.
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.
5x(8-3)+3x-2
use the distributive property on 5x(8-3)
40x - 15x + 3x - 2
simplify
28x - 2
there's your answer
