What is 0.6 of 50%

OpenStudy (e.mccormick):

Know how to get a fraction of a fraction?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

0.6*0.5

OpenStudy (e.mccormick):

You multiply them. So put them in one form, like fraction form or decimal form, then multiply them.

OpenStudy (anonymous):

I dont know much about Percentages and any1 know anything abot functions???

OpenStudy (anonymous):

0.6*0.5

OpenStudy (anonymous):

Mcormmick is that right?

OpenStudy (e.mccormick):

A percentage means per-centum, or per 100. It means you take the number and divide it by 100. so 50% = \(\dfrac{50}{100}\) = .5 Thus, 50% in decimal form is .5. That is why iamabarbiegirl says those are the numbers to multiply.

OpenStudy (anonymous):

Do you know how to do Functions??

OpenStudy (anonymous):

yeah because you cannot multiply decimals with percentages its basiccally impossible unless you change the percentage into a decimal by doing that you just divide the percentage by 100

OpenStudy (e.mccormick):

A function is just a pre-made equation of some sort. In fact, what I did to describe how to change 50% to a decimal is essetially a function.

OpenStudy (anonymous):

Wel can you guys/girls help me with them its due tommorow for me and its 8;00

OpenStudy (e.mccormick):

Well, what do you get when you multiply those?

OpenStudy (anonymous):

Multiply what

OpenStudy (anonymous):

0.6 and 0.5

OpenStudy (anonymous):

multiply them and tell us what you get as ur answer

OpenStudy (anonymous):

0.3

OpenStudy (e.mccormick):

Yep.

OpenStudy (anonymous):

Got it!

OpenStudy (anonymous):

Which of the following relations is not a function? (6, 4), (-2, 2), (4, 1), (-7, 2) (4, 4), (-2, 2), (4, 1), (-7, 2) (-7, 4), (4, 3), (-2, 1), (6, 2) (-2, 4), (4, 2), (6, 1), (-7, 5)

OpenStudy (e.mccormick):

A fraction of a fraction or a percentage of a fraction or a percentage of a percentage is all basically the same thing. Just multiply them. For that second one, those are (x,y) pairs. For something to be a function, for any x there can be one and only one y. So if for some x you can get 2 or more different y values then it is NOT a function.

OpenStudy (anonymous):

so (6,4) JUST MULTIPLY??

OpenStudy (e.mccormick):

No. The fraction comment was for the first question. The second paragraph is for the second question.

OpenStudy (anonymous):

What about the function oone??

OpenStudy (e.mccormick):

"those are (x,y) pairs. For something to be a function, for any x there can be one and only one y. So if for some x you can get 2 or more different y values then it is NOT a function."

OpenStudy (anonymous):

I guess im going to fail :(

OpenStudy (e.mccormick):

Let me show you two examples: (1, 2), (2, 4), (4, 4), (5, 15) There you have different X values for all of them. Now, two of the y values match. That is OK! It can be a function with two matching y values. Now for the second example: (1, 2), (2, 4), (2, 6), (5, 15) That CAN NOT be a function! Why? Because when x=2 the y can be either 4 or 6.

OpenStudy (anonymous):

:(

OpenStudy (anonymous):

Which of the following statements correctly describes the items shown below? The items are both increasing and are not parallel. The items are parallel to each other. The items are both increasing and are parallel. The items are not parallel to each other.

OpenStudy (anonymous):

Guys plz i need answers it due tommorow and ill give all of you 20 medals i just need to get it done :(

OpenStudy (e.mccormick):

Well, what do you think and why?

OpenStudy (anonymous):

That doesnt help im asking because idk help

OpenStudy (anonymous):

I will give 20 medals to whoever gives answers! :(

Nnesha (nnesha):

hmmm asking for direct answer 4rm mod not good

OpenStudy (e.mccormick):

Well, it does not help you answer things if I just do the work. I am trying to see where you are having a problem with the question.

OpenStudy (anonymous):

IDK thats the problem

OpenStudy (anonymous):

Okay listen this is the only hard one and the others were easy Best Fit Lnear Models and scattered plots.Tis is just the only thing i have cried because this is so hard

OpenStudy (e.mccormick):

Well, you have four possible statments that involve two things, parrallel and increasing. So, the question could be reworded as, "Are these parallel and are they increasing?" Do you know how to test those two things?

OpenStudy (anonymous):

No

Nnesha (nnesha):

oky relax nothing is hard just take a deep breath and focus on t what he trying to explain

OpenStudy (anonymous):

:(

OpenStudy (e.mccormick):

Increasing or decreasing has to do with slope. |dw:1422494698829:dw|

OpenStudy (e.mccormick):

So, which of those three situations applies to y=12?

OpenStudy (anonymous):

increasing

OpenStudy (e.mccormick):

Hmmm... |dw:1422494857971:dw| Typical xy graph...

OpenStudy (e.mccormick):

|dw:1422494949518:dw|

OpenStudy (e.mccormick):

Does it still look increasing?

OpenStudy (anonymous):

nope decreasing

OpenStudy (e.mccormick):

Because the y is always 12 it is not going up or down. It is flat, a horozontal line.

OpenStudy (anonymous):

so not parrallel toeach other

OpenStudy (e.mccormick):

Well, that is just the first line. Now, the second line can only be parallel if it is also flat because then they will both have no slope.

OpenStudy (e.mccormick):

Now, this is not the best drawing... but, there are the two points: |dw:1422495140968:dw|
