The average (arithmetic mean) of 4 numbers is greater than 7 and less than 11.What is one possible number that could be the sum of these 4 numbers? I need an explanation.
Thank you.What is one possible number that could be the sum of these 4 numbers?
Anything bigger than 28 and less than 44, in symbols
28 %26lt; SUM %26lt; 44
Because Sum = Mean 鈥?CountWhat is one possible number that could be the sum of these 4 numbers?
average implies sum up the numbers you're talking about and then divide by the number of numbers you have. Since you have 4 numbers, simply take the average and multiply by the number of numbers to get the sum. In this case, the average can be 8, 9, or 10. so if we multiply those by 4, we get 32, 36 and 40. (I only examined whole number averages here, there can be more if the average is a decimal)
32, 36, 40.
These are numbers between 7 and 11 multiplied by 4.
