Answer: hello your question is incomplete below is the missing part
Determine the proportion of radishes grown without fertilizers with weight less than 50grams
answer : p( x < 50 ) = 0.84
Step-by-step explanation:
Radish grown in without fertilizers ( normally distributed )
mean = 40 g
standard deviation = 10 g
Radish grown with fertilizers ( normally distributed )
Mean = 140 g
standard deviation = 40 g
Determine the proportion of radishes grown without fertilizers with weight less than 50 grams
lets assume x = radish without fertilizers
          y = radish with fertilizers
hence
p( x < 50 )  = P (  (x-μ / б)  < [tex]\frac{50-40}{10}[/tex]  )
         = p ( z < 1 ) = 0.5 + p ( 0 < z < 1 )
                  p( x < 50 ) = 0.5 + 0.3413 = 0.8413
attached below is the distribution related to this solution
