-- The two sides of a right <u>angle</u> intersect and make the angle. 
So do the sides of any other angle. So they can't be parallel.
-- No two sides of a right <u>triangle</u> ... or any other triangle ...can be parallel.
        
             
        
        
        
(7 + i) - (6 - 2i) = 7 + i - 6 + 2i = 1 + 3i
        
             
        
        
        
The answer is 24 guppies. First find the volume of the tank, then divide that volume by 576 (you should get 8), then you multiply 3 guppies by 8 to get 2e
        
             
        
        
        
Answer:
V = 904.32cm3
Step-by-step explanation:
V = r*r*pi*h
   = 6*6*3.14*8 = 904.32cm3
 
        
             
        
        
        
Answer:
68% Confidence interval  = [4.5752, 4.5848]
95% Confidence interval  = [4.5688, 4.5918]
Step-by-step explanation:
Sample mean (X) = 4.580
Sample Standard Deviation (S) = 0.01065
Sample size (n) = 6
 for alpha/2 0.84 = 1.1037
 for alpha/2 0.975 = 2.5706
68% Confidence interval = 
 = [4.5752, 4.5848]
95% Confidence interval = 
 = [4.5688, 4.5918]
