Alright, so the mean of anything is the total sum of items you want to find the mean of divided by the number of items, right?

tkhunny · Answer

Have you considered adding them all up to produce the total?
If you do that, you can divide the total by theh number of values, 10, and produce the mean.

so it equals 6.5 right?

anonymous · Answer

So, to start with, let's add all of those values together, like so 

$$7.50 + 10.50 +   5.00 +   4.50  +  3.50 +  7.50 +  4.00 +  10.00 +  7.50 +  5.00$$

So that would give us 65.00 in total. [It's important to write values to the accuracy of two decimal places since the values are given like that as well.]

Let's count the number of items ... 10 in total, right?

So the sum of the items is 65, and the total number of the items is 10. Now it's a simple job of dividing them to find the mean.

$$65/10=6.5$$ Which is your answer. Hopefully, my solution helped you. if you have any more problems, don't hesitate to ask.
