Salaries for teachers in a particular elementary school district are normally distributed with a mean of $49,000 and a standard deviation of $6,100. We randomly survey ten teachers from that district. (Round your answers to the nearest dollar.) (b) Find the 90th percentile for the average teacher's salary.

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.
