OpenStudy (anonymous):

OpenStudy (anonymous):

I just need them checked. I'm not confused at all, i just forgot to bubble them in sorry bout tht

OpenStudy (anonymous):

what did you get for 1?

OpenStudy (anonymous):

1. 6 2. 40 3. 3

OpenStudy (anonymous):

That's right, well done

OpenStudy (anonymous):

Can you check a few more or nah?

OpenStudy (anonymous):

sure

OpenStudy (anonymous):

ok. let me screenshot them rq

OpenStudy (anonymous):

Don't know if I got these right....

OpenStudy (anonymous):

@10115658

OpenStudy (anonymous):

what did you get for the first one?

OpenStudy (anonymous):

are the ones you selected your choices?

OpenStudy (anonymous):

yes. but idk if they right

OpenStudy (anonymous):

they're all wrong

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

for the first one, it says 'no more' this includes 12. So what should the answer be?

OpenStudy (anonymous):

either C or D

OpenStudy (anonymous):

should it be less than or greater than 12 people?

OpenStudy (anonymous):

less

OpenStudy (anonymous):

that's right, what sign is the 'less than' sign? < or >

OpenStudy (anonymous):

<

OpenStudy (anonymous):

that's right, so what 2 options can we rule out?

OpenStudy (anonymous):

c and d.

OpenStudy (anonymous):

yep. so the question says 'no more' this includes twelve. when it includes the number in question, there is a line underneath the inequality sign

OpenStudy (anonymous):

therefore, the answer is?

OpenStudy (anonymous):

so the answer is b

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

for the second question, is c larger or smaller than -1?

OpenStudy (anonymous):

smaller.

OpenStudy (anonymous):

ok, so which graphs can we rule out?

OpenStudy (anonymous):

b and d

OpenStudy (anonymous):

that's right. when it's less than and equal the graph will have a solid dot. when it's less than and not equal, it's an open dot. so what is the answer?

OpenStudy (anonymous):

c

OpenStudy (anonymous):

My computer is being super slow today

OpenStudy (anonymous):

is c also equal to -1?

OpenStudy (anonymous):

no?

OpenStudy (anonymous):

that's right, which means that the graph should have an open dot

OpenStudy (anonymous):

wait so is #5 C?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

then its A right @10115658

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Try the last question again and see what you get

OpenStudy (anonymous):

C? @10115658

OpenStudy (anonymous):

how did you get that?

OpenStudy (anonymous):

is m greater or less than -60

OpenStudy (anonymous):

Greater

OpenStudy (anonymous):

@10115658

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

and it is a closed dot, what does that mean?

OpenStudy (anonymous):

I forgot.... can ya tell me again. Can we speed this up its almost 5 and i have to get to practice

OpenStudy (anonymous):

a closed dot means equal to.

OpenStudy (anonymous):

that means the answer is?

OpenStudy (anonymous):

a

OpenStudy (anonymous):

correct, good job
