Find #(a u b u c) if #a = #b = #c = 17, #(a n b) = 5, #(b n c) = 6, #(an c) = 7, and #(a n b n c-2. you may find it to draw a venn diagram.

Step-by-step explanation:

Given that A,B, C are three non empty sets.

Use the addition theory for finding no of elements in union of two or more sets

We have addition theorem as

Now substitute for each entry from the given information

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
