Which one of the following options correctly
1 answer:
Hey there!
The answer is C.
To calculate the mean, you add all the values together then divide by the amount of values you have.
Since we are adding 5 numbers together, we divide it by 5.
Don't let the subtraction signs confuse you, it just means that some of the numbers are negative.
Hope this helps!
