Answer:
79.5
Step-by-step explanation:
1 2/5 MINUS 3/10 is 1 1/10 or 11/10
Uniform?
Pretty sure its not a unimodal/left skewed and right skewed as theres no sudden drop and the frequency are all similar
The ratio of the lengths is 75 : 25 or 3 : 1
The ratio of and area is the square of this: ie 9 : 1 or 75^2 : 25^2
(In working out the area the radius is squared)
The ratio of the volumes is the cube of this: ie 27 : 1 or 75^3 : 25^3
(In working out the volume the radius is cubed)
Hopefully this explains it
