If the hypotenuse and leg of one right triangle are congruent to the corresponding parts of another right triangle, the right triangles are congruent. The "included angle" in SAS is the angle formed by the two sides of the triangle being used. The "included side" in ASA is the side between the angles being used.

Answer:
Option C -> None of the above. 
Step-by-step explanation:
Given- 
2 r + ( t + r )
<em>⇒ 2 r + t + r</em>
<em>⇒ 2 r + r + t</em>
<em>⇒ 3 r + t</em>
∵ 2 r + ( t + r ) = 3 r + t.
∴ The given expression is equivalent to Option C : None of the above.

Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  
Part a
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
 
  
Where  and
 and  
We are interested on this probability
 
And the best way to solve this problem is using the normal standard distribution and the z score given by:
 
If we apply this formula to our probability we got this:
 
And we can find this probability like this:
 
And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  
 
Part b
For this case we select a sample size of n =32. Since the distribution for X is normal then the distribution for the sample mean  is given by:
 is given by:
 
And the new z score would be:



 
        
             
        
        
        
Hello there ^ _ ^ 
We know that 36 plates filled 1 box 
if we have 1000 plates, how many box it would fill. 
All we have to do is divide 1000 by 36 to find the answer. 
1000/ 36 = 27.77777 or you can just say 28
I hope this help!
