Answer:
Hi your question is incomplete attached below is the complete question
answer : p ( X < 725 )  = 0.0116
Step-by-step explanation:
Given data:
Average life of bulbs (μ  )  = 750 hours
standard deviation (б ) = 55 hours 
n ( sample size ) = 25 
 X = 725  
<u>Probability that the mean life of a random sample of 25 bulbs will be less than725 hours </u>
p ( X < 725 ) = p (( X - μ )/ б √n  <  725 - 750 / 55√25 )
                      = P ( Z > - 2.27 ) 
Hence P ( X < 725 ) = 0.0116  ( using Z-table )

Answer:
27
Step-by-step explanation:
green is 30%
blue is 50%
red is 6 marbles which when calculated is equal to 20%
blue would then be 15 marbles as the whole 100% would equal to 30 marbles
if 40% is added which is also 12 marbles then 15+12 = 27
 
        
             
        
        
        
I think the answer is C good luck
