Question 8(Multiple Choice Worth 1 points) PLEASE HELP (08.02 MC)

The dot plots below show the scores for a group of students for two rounds of a quiz:

Two dot plots are shown one below the other. The title for the dot plot on the top is Round 1 and the title for the bottom plot is Round 2. Below the line for each dot plot is written Score. There are markings from 1 to 5 on the line at intervals of one. There are 2 dots above the mark 2, there are 3 dots above the mark 3, there are 2 dots above the mark 4 and there is 1 dot above the mark 5. For the bottom dot plot there are 2 dots above the mark 3, there are 4 dots above the mark 4 and there are 2 dots above the mark 5.

Which of the following inferences can be made using the dot plots?

There is no overlap between the data.
Round 2 scores were lower than round 1 scores.
The range of round 1 is greater than the round 2 range.
Round 1 scores were higher than round 2 scores

answer: no idea

step-by-step explanation: i just want points

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 number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
