Answer:
x=65, y=60
Step-by-step explanation:
x=65--->corrosponding angles with the triangle
x+y+55=180--->linear pair
(65)+y+55=180
y=60
Answer: A: $1.45
Work:
$2:49 divided by 12 = 0.2075
0.2075 x 7 = 1.4525
1.4525 = 1.45
To find the mean absolute deviation, you have to find the mean first.
1+1+2+2+2+4=12
12 divided by 6 numbers=2 The mean of that is two
Next, you have to find the amount the original numbers are away from the mean.
1= 1 away from 2 2=0 away from 2 4=2 away from 2
You should get: 1,1,0,0,0,2 Next, you have to find the mean of the new set of numbers. 1+1+0+0+0+2=4
4 divided by 6= 2/3
The mean absolute deviation is 2/3
First find out what 55% of $25 is by doing 25 times .55 which is 13.75, then add 25+13.75 and that should be your answer
