The problem is in the picture

27%

Step-by-step explanation:

In the row Students ages 14-17 and column skip breakfast, there are 24 students.
In row total and column total, there 90 students.

24/90 are students age 14-17 who skip breakfast

24/90 = 12/45 = 0.26666667

Percent = decimal x 100

Percent = 0.26666667 x 100 = 26.666667

26.666667 is rounded to 27%

Hope this helps :)

Have a nice day!

step-by-step explanation:

the answer is a

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.
