Hello my fellow smart people I think the answer is 4 but I wanna be sure your supposed to find the mean

You are correct! The answer is 4

Step-by-step explanation:

Add up all the wands and divide by number of fairies in Fairyland

5+3+3+5 = 16

16/4 = 4

I think it's 1 because if we ask to find the mean we have to follow this formula --> sum/the number of materials are there. In that case, what I did was:

there is 16 wand and each one equals to 1 which means the sum of the wand is 16. 16/16=1

I am not sure but hope it's right and helps you!

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
