To find the average of the numbers 8, 7, 7, 5, 3, 2, and 2, add them together to get a total of 34. Then, divide this sum by the number of values, which is 7. This calculation results in an average of 4 and 6/7, confirming that the correct answer is (c) 4\frac{6}{7}. The discussion emphasizes understanding the process of calculating the arithmetic mean rather than just obtaining the answer. Overall, the method of summation followed by division is key in solving basic pre-algebra problems.

I know this is basic stuff, but I'm barely geting back into school and starting off with a basic math class, so any help would be highly appreciated, i don't want the answers just to be pointed in the right direction. :smile:


'what is the average (arithmetic mean) of 8,7,7,5,3,2 and 2'

(a) 3\frac{4}{7}

(b) 4\frac{5}{6}

(c) 4\frac{6}{7}

(d) 5

(e) 6\frac{4}{5}

Just add them all up, and divide by the total number of numbers you have.
 
so the answer is (c) 4\frac{6}{7}which i got by adding the numbers up which is 34 and dividied by that total which is 7, so 34 divided by 7 is 4 remainder 6 which gives me 4\frac{6}{7}right?
