Step-by-step explanation:
1. To find the mean absolute deviation of the data, start by finding the mean of the data set.
2. Find the sum of the data values, and divide the sum by the number of data values.
3. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
4. Find the sum of the absolute values of the differences.
5. Divide the sum of the absolute values of the differences by the number of data values.
Answer:
3
Step-by-step explanation:
3(2-1)=6-3=3
36 divided by 4 = 9
so then you take 3 times 9 which is 27 so the answer is
g=27
Answer: 210 advanced tickets were sold. 130 same day tickets were sold.
Step-by-step explanation:
x= advanced tickets y=same day tickets
2x+3y=810 this equation represents the money
x+y=340 this equation represents the total number of tickets
x+y=340
<u>-x -x</u>
y=-340-x 2x+3(340-x)=810 210+y=340
2x+1020-3x=810 <u> -210 -210 </u>
-x+1020=810 y=130
<u> -1020 -1020</u>
<u>-x</u>=-<u>210</u>
-1 -1
x=210
Answer:
6.75
Step-by-step explanation:
you cross multiply to get rid of the fractions
so it would be 4x = 27
divide the four on both sides
x = 27/4
x = 6.75
