By definition, the volume of a sphere is given by:
 V = (4/3) * (pi) * (r ^ 3)
 where,
 r: radius of the sphere.
 Substituting we have:
 V = (4/3) * (pi) * ((3) ^ 3) = 113.08 in ^ 3
 answer
 the best estimate for the volume of air in the balloon in cubic inches is
 C. 113.1
        
                    
             
        
        
        
Answer: If you're not vegetarian, then you do not eat beef.
Step-by-step explanation: 
Dismiss the 'if' and 'then':
- you do not eat beef
- you're not vegetarian
Now, all you have to do is switch their places:
- you're not vegetarian
- you do not eat beef
Now add the 'if' and 'then' back:
If you're not vegetarian, then you do not eat beef.
 
        
             
        
        
        
The survey was intended for Bill's middle school during the summer. The 
survey was administered to students of other schools on a Saturday. 
- The type of error is the <u>selection bias error</u>.
Reasons:
The type of error made is a non sampling error, given that the target of the 
study is the number of times in a week students at his middle school 
attend the beach during the summer.
The errors are; Selection bias error.
- The given that the students survey are not from his middle school.
- The survey was carried out once on a Saturday, where the target was during the summer.
The selection bias error is a type error that is due to the researcher 
chooses what to study, such that the participant have common 
characteristics rather than being random.

Answer:
a) 131/450
b) 1233/1276  
Step-by-step explanation:
P(bad) = P(1st batch)*P(bad 1st batch ) + P(2nd batch )*P(bad 2nd batch) + P(3rd batch )*P(bad 3rd batch)
p(bad) =(60/360)*(1/3) + (120/360)*(1/4 ) + (180/360)*(1/5)
= 43/180  
And that of  P(good )
 = 1 - 43/180
 = 137/180
a)
P(defective) = P(bad)*P(defective /bad) + P(good)*P(defective /good)
= (43/180)*(9/10) + (137/180)*(1/10)
= 131/450
b)
P(Bc I Dc ) = P(good)*P(not defective |good) / P(not defective)
= (137/180)*(1 - 1/10) / (1 - 131/450)
= 1233/1276  
 
        
             
        
        
        
Answer: 158
Step-by-step explanation:

Each party goer needs 6/10 
So 95/10 / 6/0=. 95/10x10/6
=950/6 = 158.
