Michael is x. Michelle is y.
x+y=27
x-5=y

Substitute y
x+(x-5)= 27
2x-5=27
2x=32
x=16

Plug in x value
(16)+y=27
y=11

Final answer: Michael-16, Michelle-11

$x-\ amount\ of\ candy\ which\ cost\ 5,45\$\\\\y-\ amount\ of\ candy\ which\ cost\ 7,33\$\\\\ 7,33*y+11*5,45=6,14(11+y)\\\\
7,33y+59,95=67,54+6,14y\ \ \ \ | subtract\ 6,14y\\\\
1,19y=67,54-59,95\\\\
1,19y=7,59\ \ \ \ | divide\ by\ 1,19\\\\y=6,38\ pound\\\\
6,38\ pounds\ should\ be\ mixed\ with\ those\ wich\ cost\ 5,45.$

Find the absolute mean deviation of this data set:<br> 8, 8, 4, 12

nasty-shy [4]

Answer:

2 is the absolute mean deviation

Step-by-step explanation:

absolute mean deviation is

the average of the differences of the data from the average

8, 8, 4, 12

1. take the average

8+8+4+12=32 -> 32/4 = 8

2. subtract each number from this average

8 - 8 = 0

4 - 8 = 4 (there are no negative answers)

12 - 8 = 4

3. take the average of these subtractions

0+0+4+4=8 -> 8/4 = 2

4. answer: 2 is the absolute mean deviation
