Answer:
mean= 4.68
variance= 1.0296
Step-by-step explanation:
mean= n×p
n=6
p=0.78
mean= 6×(0.78)
            = 4.68
variance= n×p×(1-p)
              = 6 × 0.78×(1-0.78)
               = 1.0296

Answer: The width  is the square root of 40 or 6.32 
Step-by-step explanation:
9^2 + b^2 = 11^2  where b squared is the width  
81 + b^2 = 121 
-81              -81 
   b^2 = 40 
b= 6.32
