    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.

    so the median would be 58?

    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.

    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 ??

    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.

    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.

    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

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

    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.
