The analysis revealed that students typically work an average of 18.1 hours per week, with a standard deviation of 15.3 hours. if we consider a group of 700 freshmen at a community college, what is the probability that the average number of hours worked per week is more than 20 hours?

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.

the height of the surface increases from the center out to the sides of the road

it is c!
