Question

Which data would be best analyzed and communicated using a histogram?

Answer 1

is this the whole question? it seems like there might be answer choices that go with this

Answer 2

the daily high temperature at a woodland weather station, measured every day for a year



counts for nine different species of duck sighted on a given date



the relative percentages of plant spores found in a sample of 10,000–year–old lake muck



the average number of clams dredged up at different depth ranges (5–10 m, 10–15 m

thes are the answer choices

Answer 3

any ideas so far? notice how the histogram has "ranges" of values on the x-axis

looking at the answer choices which one also has this characteristic?

Answer 4

I would say it would be the last choice ?

Answer 5

good, well done

Answer 6

thank you for your help

Answer 7

Which statement is true?

Answer 8

A hypothesis must be based on the researcher's analysis of the data collected in the experiment.



A hypothesis must be testable for it to be useful in scientific research.



A hypothesis must be supported by the results of the research study

Answer 9

any ideas? keep in mind the hypothesis is done ~before~ any experimentation/data is collected

Answer 10

the second one ?

Answer 11

perfect

Answer 12

thx I might need help with a few more some of these question I don't understand like this one right here

Answer 13

Which of these is a hypothesis?

Answer 14

Salmon are kept in their natural habitat and treated with fungicides whenever infected.



The yield of salmon is 2,000 kilograms in the month of April and 1,500 kilograms in the month of October.



Salmon are more prone to infections during the summer than in other seasons

Answer 15

well a hypothesis must be testable, it can't just be a factual statement

that being said which statement might be the best hypothesis?

Answer 16

well, let's use process of elimination

"The yield of salmon is 2,000 kilograms in the month of April and 1,500 kilograms in the month of October."

this is more along the lines of a factual statement rather than something that can be tested/experimented on, so let's eliminate B

Answer 17

i want to say the first one

Answer 18

hm, that's a good guess, but I'd still say C is the better option because it allows the experimenters to create an experiment comparing infection rates in salmon in different seasons

Answer 19

A is more along the lines of an experimental procedure/directions rather than a hypothesis

Answer 20

ok thx and that is right because they can experiment

Answer 21

yeah sorta

Answer 22

ok ill text you if i need anymore help

Answer 23

A certain skin lotion is a fine mixture of water and various oils. This lotion is cloudy and cannot be separated into oil and water by filtration or centrifuge. What type of mixture is it?


colloid



suspension



solution

i think its the first one

Answer 24

good

Answer 25

ok we gonna be here for a while if that's fine with u

Answer 26

I can't stay on all day but I'll do what I can

Answer 27

ok

Answer 28

Oxygen is denoted How many protons and neutrons does an oxygen atom have?


16 protons and 16 neutrons



8 protons and 8 neutrons



8 protons and 16 neutrons
i think its the last one

Answer 29

does it say something like

16 O
8

if so then yes

Answer 30

yea

Answer 31

yeah then i agree w/ the last choice

Answer 32

13C and 14C are isotopes of 12C, which has 6 electrons, 6 protons, and 6 neutrons. What is the arrangement of subatomic particles in 14C?

6 electrons, 7 protons, and 6 neutrons



6 electrons, 7 protons, and 8 neutrons



6 electrons, 6 protons, and 8 neutrons

I think its the second one

Answer 33

hm. you have to be careful. any isotope of carbon is still carbon so it will only have 6 protons not 7

Answer 34

ok so the last one?

Answer 35

good

Answer 36

Covalent bonds are in the air you breathe and the water you drink. How are covalent bonds formed?

between atoms with more electrons than protons



between atoms that share electrons



between atoms with more neutrons than protons

I think its the last one or the first one

Answer 37

the distinguishing feature of a covalent bond is that the atoms ~share~ electrons

Answer 38

?

Answer 39

nevermind I understand now

Answer 40

Calcium oxide (CaO) forms when an atom of calcium loses two electrons, giving it a +2 charge and an atom of oxygen picks up two electrons, giving it a –2 charge. What is calcium oxide?

an element



a covalently bonded compound



an ionically bonded compound


is it the second one?

Answer 41

hm. not quite. covalent would be sharing two electrons, but here the calcium is "stealing" two electrons from the oxygen

so it's the other type of bond

Answer 42

so the last one?

Answer 43

yup

Answer 44

ok

Answer 45

anyway I kind of need to get going, I think @nuts should know how to do this if he's available for help

Answer 46

you can use the @ symbol to tag someone and get their attention

Answer 47

ok thx
