@britanyashton come help me plz give medal and fan

OpenStudy (anonymous):

this is quision 3 2 more after this one

OpenStudy (britanyashton):

Ok this is actually really simple. its just that they ask it in a weird way. they're purposely trying to throw you off a bit. how do you think we should start it?

OpenStudy (anonymous):

i truly dont know

OpenStudy (britanyashton):

pick out the information that you need. the other is just fluff. Things we know 1) we're looking for reading. 2) they DO NOT ride motorcycles.

OpenStudy (anonymous):

yes true so then wat is our next step

OpenStudy (britanyashton):

find that information on the chart. what is the number there? how many have both of those characteristics?

OpenStudy (britanyashton):

they read and do not ride a motorcycle. how many?

OpenStudy (anonymous):

5 i think

OpenStudy (britanyashton):

yes! dont say "i think"- you know! :) Now that we have that, we should cover what relative frequency. Example: Your team has won 9 games from a total of 12 games played: the Frequency of winning is 9 the Relative Frequency of winning is 9/12 = 75% Look at that. From using this as a reference, how should we go from there? if you don't know that is okay. cause youll know afterwards anyways.

OpenStudy (anonymous):

ok so 5 is the answer

OpenStudy (britanyashton):

no. not there yet.

OpenStudy (britanyashton):

that is the number of people that do. but we need the percentage of people that have that.

OpenStudy (britanyashton):

so the next step, would be to add up to find the complete total of people in the entire survey.

OpenStudy (britanyashton):

but right down that 5 on your paper, cause you will need that again later.

OpenStudy (anonymous):

ok theres 24 people in the whole entire survey

OpenStudy (britanyashton):

To find all of the people (how many there are in the survey) add 7+3+5+9

OpenStudy (britanyashton):

yes

OpenStudy (britanyashton):

5/24= what does that equal?

OpenStudy (britanyashton):

use your scientific calc

OpenStudy (britanyashton):

find the decimal

OpenStudy (anonymous):

yea can u solve that for me its giving me abunch of numbers can u do it and tell em wat u got

OpenStudy (britanyashton):

Yep. You're supposed to get those numbers. That is why we round. Go two decimal places to the right. When you do, you get 20%

OpenStudy (britanyashton):

or in decimal .20

OpenStudy (anonymous):

ok so we did it rite thats it

OpenStudy (britanyashton):

.20 is the decimal. Yep we did. What confused you about this?

OpenStudy (anonymous):

well all the steps but now it seems real simple

OpenStudy (britanyashton):

That is great! You could have probably figured this out on your own. Now is that all, or do you think you can figure out the rest on your own?

OpenStudy (britanyashton):

&*

OpenStudy (anonymous):

OpenStudy (anonymous):

i need help with this one and one more

OpenStudy (britanyashton):

okay. lemme look at this one.

OpenStudy (anonymous):

k

OpenStudy (britanyashton):

it will benefit you, and will make sense.

OpenStudy (britanyashton):

for that problem.

OpenStudy (anonymous):

u dont know how to solve it

OpenStudy (britanyashton):

i do. but this could help. plus im in a livelesson right now. lol

OpenStudy (britanyashton):

thisll give you an example to go off of.

OpenStudy (anonymous):

wait are u in 8th grade k12 and yur helping me alot so plz help me

OpenStudy (britanyashton):

no im in 11th grade. wisconsin connections academy. okay. but itll help you.

OpenStudy (anonymous):

ok

OpenStudy (britanyashton):

ok look at the question: it asks: What percent of the people who chose ham sandwiches are boys? how many-look at the chart boys that chose ham sandwiches: 0.625 then round that to the nearest hundreths place

OpenStudy (anonymous):

is it 60%

OpenStudy (anonymous):

600%

OpenStudy (britanyashton):

tell me-how many people in total (boys and girls) chose ham sandwiches?

OpenStudy (anonymous):

is it 600%

OpenStudy (britanyashton):

woe no not 600% there aint such thing. 100% is the most you can get.

OpenStudy (britanyashton):

just two places to the right.

OpenStudy (britanyashton):

soo... two dec places of .62 is?

OpenStudy (anonymous):

o ok so wat did u get

OpenStudy (anonymous):

0%

OpenStudy (britanyashton):

im showing you how to get it-not telling you lets do this afterwards actually. First tell me how many boys and girls in total got a ham sandwich add together their numbers.

OpenStudy (anonymous):

its 1

OpenStudy (britanyashton):

.375 + .625 =1 yes. perfect! 0.625/1

OpenStudy (britanyashton):

Same thing now. What does .625 represent again? How about 1? (want to make sure you're following

OpenStudy (anonymous):

its 0.625

OpenStudy (britanyashton):

yes. now try again with rounding. round two dec places to the right.

OpenStudy (britanyashton):

Look at that chart I gave you.

OpenStudy (britanyashton):

OpenStudy (anonymous):

is it 5

OpenStudy (britanyashton):

hundreths place.

OpenStudy (britanyashton):

that tenth place

OpenStudy (anonymous):

6 or 2

OpenStudy (britanyashton):

you are incredibly close. you can do this. .62

OpenStudy (britanyashton):

You need to review rounding.

OpenStudy (anonymous):

o so its .62

OpenStudy (britanyashton):

other than that, this problem wasn't that bad.

OpenStudy (britanyashton):

yes.

OpenStudy (anonymous):

wo lol thx

OpenStudy (britanyashton):

mhm :)

OpenStudy (anonymous):

OpenStudy (britanyashton):

to review: watch this https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-data/two-way-tables/v/two-way-relative-frequency-tables I promise from the very bottom of my heart this will be amazing

OpenStudy (anonymous):

last one

OpenStudy (britanyashton):

ok

OpenStudy (anonymous):

OpenStudy (anonymous):

i got 2 or 11 is the answer
