Francis surveyed a random sample of 707070 students at Franklin High School about their favorite season. Of the students surveyed, 181818 chose fall as their favorite season. There are 181618161816 students at Franklin High School.

467 students

Step-by-step explanation:

Rest of the question is:

Based on the data, what is the most reasonable estimate for the number of students at Franklin High School whose favorite season is fall?

Out of 70 students surveyed, 18 said Fall was their favorite season.

In percentage terms this is:

= 18 / 70 * 100%

= 25.71%

If there are 1,816 students in the school, with the above percentage, a reasonable estimate of people who prefer fall in the school is:

= 25.71% * 1,816

= 466.8

= 467 students

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.
