PLEASE HELP

Thirty sixteen-year-olds took the driving test to obtain their driver's license. The following chart shows the number of times each one had to take the test before passing.

1 3 1 1 2 1 2 3 2 1
2 1 1 3 2 1 1 1 1 2
1 1 2 1 3 2 1 1 1 2
Based on the above data, what is the mode?

1

Step-by-step explanation: Mode is the number that occurs the most. 1 occurs 17 times, 2 occurs 9 times and 3 occurs 4 times, so the mode is 1.

y + 11 = (1/4)(x + 16)

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.
