Answer:
16
Step-by-step explanation:
The first week she got 2 cakes
The second week she got 4 cakes
The third week she got 8 cakes
The formula is x*2
2*2 = 4
4*2 = 8
8*2 = 16
Finding the mean is you have to add it all up:
49+55+52+46+47+42+38= 328
The divide it by the amount of numbers so, 329/7= 47.
Subtract 47 from every number then, but even if you get a negative number you gotta keep it a positive so just ignore it if you get a negative answer when subtracting, once you do that you would add up those answers you got so;
2+8+5+1+0+5+9= 30
Then divide it again, 30/7
Which then you get the M.A.D which is 4.3, rounded to the nearest ten.
Step-by-step explanation:
Let 8=x
A
Depending on its position increases its value x10.
EX:
300 30 3 0.3 0.03
The number continually is raised x10 the more you move it to the right and is divided by 10 when you move it to the left
