A group of 6 students was asked, "How many hours did you watch television last week?" Here are their responses.
6, 19, 16, 6, 17, 6
Find the mean number of hours for these students.
If necessary, round your answer to the nearest tenth.

11.7

Step-by-step explanation:

Mean = sum of responses/ number of responses

Add the responses together then divide by number of responses.

= 6+19+16+6+17+6/6

=70/6 =11.667

11.667 to the nearest tenth = 11.7

I hope this helps.

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.
