Step-by-step explanation:
This is a probability related problem. 
   Probability is the likelihood of an event to occur; 
     Pr = 
The sample space here is from 1 to 25 which is 25
A. 
Pr of a card marked 8; we have just 1 possible outcome;
        Pr(8)  =  
 
B. 
Pr  of drawing a card that is a multiple of 5; 
     Multiples of 5 = 5, 10, 15 and 25 
      Pr (multiples of 5) =  
 
C. 
Pr of drawing a card with odd numbers: 
           Number of odd numbers between 1 and 25  = 13 
      Pr(odd numbers) =  
 
D. 
Pr of drawing a number with square number on it;
         Square numbers between 1 and 25  = 1, 4, 9, 16 and 25
   Pr(square numbers) =  =
   =

Let 

 denote the random variable for the weight of a swan. Then each swan in the sample of 36 selected by the farmer can be assigned a weight denoted by 

, each independently and identically distributed with distribution 

.
You want to find

Note that the left side is 36 times the average of the weights of the swans in the sample, i.e. the probability above is equivalent to

Recall that if 

, then the sampling distribution 

 with 

 being the size of the sample.
Transforming to the standard normal distribution, you have

so that in this case,

and the probability is equivalent to

 
 
        
        
        
Answer:
 height equals 5 inches 
Step-by-step explanation:
base = 6
area = 15
area = 1/2(6)h
 15= 3h
 5=h
