Answer:
$307.5. 
Step-by-step explanation: 
We have been given that Elena's aunt bought her a $150 savings bond when she was born.When Elena is 20 years old, the bond will have earned 105% in interest.  
To find bond's value after 20 years we will add 105% of 150 to 150.




Therefore, the bond will be worth $307.5, when Elena will be 20 years old.
 
        
             
        
        
        
Answer:
a) .033  b) .4678 c) 100
Step-by-step explanation:
Distribution of miraculin produced is normal. To answer question we need to find the z-score of 100g, 110g and 120g miraculin
General formula for z score is given by 
z= where
 where
- X is the miraculin produced (120,110,100)
- M is the mean miraculin produced for a partucilar tomato plant, which is 105.3
- s is the standard deviation of the sample, which is 8.0
a) 
z-score for 120 g miraculin is  =1.8375 then
 =1.8375 then
P(x > 120) = P(z>1.8375) = 0.033
b) 
z-score for 110 g miraculin is  = 0.5875
 = 0.5875
   z-score for 100 g miraculin is  = -0,6625
 = -0,6625
P(100 < x < 110) = P(x>100) - P(x>110) =0.7462 - 0,2784 = 0.4678
c)
if P(x < a) = 0.25 then corresponding z score for a is -0.6745. From the above formula we can calculate a:
 =-0.6625 which gives a= 100
 =-0.6625 which gives a= 100
