The results of a survey of common allergies was organized into a venn diagram. answer the questions about the following sets: d = {x | x is a person allergic to dogs); c = {x | x is a person allergic to cats); p = {x | x is a person allergic to pollen} 15 . 18 how many people are not allergic to any of the three choices? how many people are allergic to all three choices? how many people are allergic to both dogs and cats but not allergic to pollen? how many people are allergic to cats only?

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

answer: sensy

step-by-step explanation:

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.
