what does mode mean in line plots

answered Jan 2, 2012 by anonymous
mode mean means the  mean that occures most often. First you have to find the mean by adding up all the numbers and dividing by how many there are. then see if it occures most often, if not there isn't one.

I BELIEVE THAT IS HOW YOU DO IT I AM NOT SURE IT HAS BEEN SO LONG SINCE IVE SEEN THE WORDS MEAN, MEDIAN, AND MODE.

what is the answer to 2(a+5)+3(a-3)
answered Jan 15, 2012 by anonymous
2(a + 5) + 3(a - 3)
= (2a + 10) + (3a - 9)
= 2a + 10 + 3a - 9
= 2a + 3a + 10 - 9
= 5a + 1
i think you are right Al i mean im in 9th grade just got done with it about 3 months ago and i really do think that that is how you find the mean, median, and mode lol good job took me a long time to remember how to do it but i finally remembered how to do it.
