Answer:
1.282, -0.5244,...
Step-by-step explanation:
We know that Z is a standard normal variate with mean =0, and std dev =1
a) z-score separates the highest 10% from the rest of the scores
= 90th percentile = 1.282
b) z-score separates the lowest 30% from the rest of the scores
= 30th percentile = -0.5244
c) z-score separates the lowest 40% from the rest of the scores
= 40th percentile = -0.2533
d) z-score separates the lowest 20% from the rest of the score
=20th percentile = -0.8416
 
        
             
        
        
        
Answer:
1.2218 atm
Step-by-step explanation:
From ideal gas formula,
PV=nRT
Where n= number of moles
V= volume
T= temperature=25.0°C
= (273 + 25) = 298 K
 R= gas constant = 0.082 l atm /K mol.
Making P subject of formula we have
P= [nRT] /V
Then substitute the values we have
P= [0.5 x 0.082 x 298] / 10 
P= 1.2218 atm
 
 
        
             
        
        
        
Answer:
41.6 centimeters 
Step-by-step explanation:
The right triangle formula: c^2 = a^2 + b^2
                                   c is the hypotenuse side of the triangle 
                                   a and b are the legs of the triangle.    
  Find the hypotenuse :   c^2 = (24)^2 + (34)^2
                                           c = square root of (  (24)^2 + (34)^2)
                                           c = square root of ( 576 + 1,156)
                                           c = 41.6173
