Answer:
Percentile 5
 
And if we solve for a we got
 
Percentile 95
 
And if we solve for a we got
 
Step-by-step explanation:
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
 
  
Where  and
 and  
We want to find the percentiles 5 and 95 for this case.
Percentile 5
For this part we want to find a value a, such that we satisfy this condition:
 (a)
   (a)
 (b)
   (b)
We want to find a percentile with 0.95 of the area on the left and 0.05 of the area on the right it's z=-1.64. On this case P(Z<-1.64)=0.05 and P(z>-1.64)=0.05
Using this condition we got:
 
  
 
Replacing we got:
 
And if we solve for a we got
 
Percentile 95
 
And if we solve for a we got
 
 
        
             
        
        
        
Answer:
x = -8
Step-by-step explanation:
y = 3x/4
Substitute the value of -6 into y.
-6 = 3x/4
Multiply both sides by 4.
-24 = 3x
Divide both sides by 3.
x = -8.

Answer:
512 ounces
Step-by-step explanation:
there are 16 ounces in a pound so you multiply 4 x 16= 64 ounces for the 4 pounds. Since Dustin had 8 pots you multiply 64 x 8= 512 ounces.
 
        
             
        
        
        
X=60 
That’s the answer 
What I did to get it 
(3x-60)=120 
 +60. +60 
3x =180
————. = 60
 3 
X=60
