How many elements are in the union of four sets if
each of the sets has 100 elements,
each pair of the sets shares 50 elements,
each three of the sets share 25 elements,
and there are 5 elements in all four sets?

20

Step-by-step explanation:

Let A, B, C and D sets.

Let |A| the number of elements of A.

Remember, the quantity of elements that have the set is

1. Since each set has 100 elements,

2.  each pair of the sets shares 50 elements

3. each three of the sets share 25 elements,

4. the four sets share 5 elements

Then

So, there are 20 elements in the union of the sets A, B, C and D

i cant see the graph

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
