What is the difference between Elementary algebra and Pre Algebra?
The difference is just the grade level. Elementary algebra is more of 4th 5th and maybe 6th. Pre algebra is more 6th 7th and possibly 8th.
How do you find a median if there is 8 numbers?
List the numbers in numerical order. You are looking for the middle number. In this case it will be the number halfway between the 4th and 5th number. Add the 4th and 5th numbers and divide them by 2, or find the number exactly halfway between the 4th and 5th numbers. So if your 4th number was 12 and your 5th number was 16, then the value halfway between them or the number that is half of the value when you add the two together is 14. That is the median.
If you are 10 what grade you in?
In the United States, most 10 year olds are either in 4th or 5th grade.
What is the power function from this data x 1 2 3 4 5 6 y2 6 10 15 23 30?
It will have to be a very complex power function because the are not increasing steadily. The increase between the 5th and 6th term is smaller than that between the 4th and 5th terms.
If you choose any phone number at random what is the probability the fourth digit will be 6?
It is best to assume independence between the numbers (i.e. the 4th doesn't affect the 5th)If that is true, then the odds are .1(We don't have to worry about area codes exist, or about avoiding 911, since this is the 4th digit)
