Question

what is the mean, median, mode of data : a) 25,21,38,29,32,44,38,21,16 4:47 pm

Answer 1

Whatcha need? I can help. You've got the median and mode already, yeah?

Answer 2

yea but i need another help too

Answer 3

25,21,38,29,32,44,38,21,16

Helps to put them in order first:

16, 21, 21, 25, 29, 32, 38, 38, 44

From here, the mean is the average. So take all of the numbers, add them up and divide them by the number of numbers you have in your list (in this case nine).

Mode is the number that shows up the most. In this case you have two numbers that each show up twice.

Median is the number in the middle of the sequence. Start from the outsides and cross em off one by one, one from the left, one from the right, until you reach the center number. This one is easy because there are an odd number of numbers, you will get one number for the median.

Hope that helps.

Answer 4

so the median would be 58?

Answer 5

The median, or middle number is 29.

The MEAN, which means average, without doing any math, I can tell you it is not 58.

Add all the numbers together and then divide by the number of numbers in the sequence. There are nine numbers in this sequence. Add them and divide by nine.

Answer 6

29

Answer 7

29 and 1/3.

Answer 8

(16 + 21 + 21 + 25 + 29 + 32 + 38 + 38 + 44)/9.
1 2 3 4 5 6 7 8 9

Answer 9

sorry i gave the wrong number ..so for instance i rearranger the numbers in to median such as , 36,38,44,53,58,71,74,81,82,94 .. so the median would be 58 ??

Answer 10

Also, I just read chat. There is such a thing as having 2 modes.

Answer 11

the median is 58+71/2

Answer 12

In that case, you have 10 numbers so there will be two numbers in the center. The median is those two numbers added and then divided by 2.

Answer 13

yay i got it :) thankyou

Answer 14

Np.

Answer 15

Could you help me as well?

Answer 16

I am almost out of time, but if it's in my knowledge, I will do my best to help.

Answer 17

Here's the equation -> 4x^2+20x-24=0 and I've gotta factor and solve. I'm able to get the first step, and afterwards I dunno where to go.

Answer 18

So let's take out 4 first. Notice how the coefficients and constant can all be divided by 4 so we can do:

4(x^2+5x-6)=0

Answer 19

If you distrubute that, you'll notice that it is the same as 4x^2+20x-24=0

Answer 20

I get that much.

Answer 21

Awesome.

Answer 22

We are going to leave that four alone for now. I'll explain it later.

Can you factor (x^2+5x-6)?

Answer 23

Remember, the formula looks like (x+?)(x+?).

Answer 24

It'd be

Answer 25

(x+6)(x-1)

Answer 26

The two ? should ADD to 5, the MIDDLE term.

The two ? should MULTIPLY to -6, the LAST TERM (aka the constant).

Answer 27

Great, that is exactly right.

Answer 28

i need help

Answer 29

So, if (x+6)(x-1) = (x^2+5x-6), can you agree that 4(x^2+5x-6)) = 4 (x+6)(x-1) ?

Answer 30

So the four is allowed to stay out there ;) All remains balanced.

Answer 31

Are we clear on this?

Answer 32

the table shows the prizes awarded in jason's school funraiser : price value : 100,50,10 , number of prices 2,4,10 find the mean median mode

Answer 33

Yeah. Do you have to go now?

Answer 34

I have to change classes, but I have computers in there too ;) It might be a couple minutes before I can come back.

Answer 35

The bell just rang, so I will be right back in maybe 10.

Answer 36

Okay. Tell me later what age you are if you can.

Answer 37

the table shows the prizes awarded in jason's school funraiser : price value : 100,50,10 , number of prices 2,4,10 find the mean median mode hellllpppp

Answer 38

Okay, I can, give me a minute

Answer 39

:) please

Answer 40

Eh

Answer 41

I'm confused by the number of prices part

Answer 42

what part you go confused?

Answer 43

Well, did you mean number of prizes, maybe?

Answer 44

yes thats exactly what i meant

Answer 45

Okay so, to solve for the three..beginning with median..

Answer 46

yh?

Answer 47

I think you needa arrange the numbers in order from lowest to highest.

Answer 48

how

Answer 49

k for median i got 31.25 ,

Answer 50

I believe you solved for the mean.

Answer 51

Noooo i dont get mean and mode and thatss y i need your help

Answer 52

Mkay, so for mean: you must add up all the values and divide by the number of values listed.

Answer 53

The mode is the most common number, so it'd be 10.

Answer 54

And then the median is what's in the middle: med=mid; you could remember it that way, I suppose.

Answer 55

You have six values, which is an even number, so there isn't really a centered value, so in this case, you select the two values in the middle and take their average.

Answer 56

i still dont get mean :S is it 8?

Answer 57

10 + 50 + 10 + 2 + 4 + 10 = Your answer. So use a calculator to add those values up first.

Answer 58

u missed 100 i guess

Answer 59

My bad, typo, it would be 100, yeah.

Answer 60

176

Answer 61

/2?

Answer 62

Good, now divide by how many values/numbers are listed.

Answer 63

So it'd be six.

Answer 64

29.3

Answer 65

Correct. That's the mean. The average. Now you needa find the median.

Answer 66

how am i gonaa??

Answer 67

2, 4, 10, 10, 50, 100

Answer 68

See how there isn't a number directly in the middle?

Answer 69

So you'd either take the average of the two middle-ish numbers, and if they're the same, they're both considered the median.

Answer 70

If it were 2, 4, 7, 9, 50, and 100, the median would be 9.

Answer 71

Kidding, 8.

Answer 72

yea i told u in the beh=ginig itss 8 lol but back of the book it shows 10

Answer 73

Do you need to show your work? If you have answers in the back of the book, you just need to jot down the steps that give you those answers.

Answer 74

i said back of the book its sayss 10 for the median.. but i got 8 .. so i dont kno whats the right answer

Answer 75

Tell me how you got eight.

Answer 76

i added the number of prices which is 2+4+6=16/2

Answer 77

Median is middle, remember that. Med=mid.

Answer 78

So you don't even need to do any calculating, you just need to determine which value/number is in the center.

Answer 79

oh i got it :)

Answer 80

And I hafta go soon, I have a math exam tomorrow morning that I need to study for, but I want you to solve for mean, median and mode of the example equation I'm gonna give you.

Answer 81

Very nice guys, good deal. I got a little waylaid but everything looks to be in order ;)

Answer 82

thankyou soo much :)good luck for ur exam

Answer 83

Dude, IParke, can you make sure this fella knows what he's doing? I dunno if he's got it down yet, so if you've got time, give him random scenarios to work with ie finding mean, median and mode and all. Can you do that?

Answer 84

If he needs help, I got him covered.

Answer 85

MSW, would you like a practice set of numbers?

Answer 86

hahahahhahhaa :P *this fellow *was referring to me ??? :P

Answer 87

lol why the heck do ur questions have over 80 replies all the time??

Answer 88

Please go away if you're not gonna assist. That's a rhetorical question, anyway.

Answer 89

And yes MSW, I was referring to you.

Answer 90

i do assist actually.. anyone needs help?
