Step-by-step explanation:
the max. value is when the smaller set (A) is completely contained in the larger set (B).
then n(A n B) is n(A) = 50.
the set intersection between A and B cannot get bigger than that. or A gets bigger ...
after all, the intersection means it is a set of all elements that exist in BOTH sets.
but then there must be other elements besides A and B in the universal set too, because n(universal set) = 96, and n(A u B) would be only 60.
the min. value could be the empty set or 0. but because n(universal set) = 96, and n(A) + n(B) = 110 and larger than 96, it means that there have to be some shared elements. at least 110 - 96 = 14 elements.
in this case there cannot be other elements in the universal set than A and B. and n(universal set) = n(AuB) = 96.
Answer:
Rotation.
Step-by-step explanation:
There are three rigid motions (which do not change the shape and size of the figures): rotation, translation and reflection.
You make a rotation of a figure when you turn it about a fixed point (which can be inside, on an edge or outside the figure) and it is measured in degrees. The rotation can be clockwise or counterclockwise.
Answer:
63/4
Step-by-step explanation:
Let the sails yard in 8 3/4 minutes= X
7 1/2 yards sails= 4 1/6 minutes
X = 8 3/4 minutes
Let us Convert the fraction to improper fraction
4 1/6 minutes= 25/6 minutes
8 3/4 minutes= 35/4 minutes
7 1/2 yards sails= 15/2 sails yard
Then
15/2 yards sails= 25/6 minutes
X = 35/4 minutes
If we cross multiply
25/6 X = 15/2 × 35/4
25/6 X =525/8
6 × 525= (25× 8)X
3150= 200X
X= 3150/200
X=63/4
