Answer:
the means absolute deviation is 1.8
the striking deviation is 7
(it is because the data point on the far right of the graph)
Step-by-step explanation:
calculate the absolute deviation:
1. calculate the mean (add all numbers and divide by 10) = 2.6
2. find the absolute value of each
2.6 - 0 = 2.6
2.6 - 1 = 1.6 (you have 1's 4 times so each one will be 1.6)
2.6 - 3 = 0.4
2.6 - 4 = 1.4 (you have 4's 3 times)
2.6 - 7 = 4.4
3. Then add all of those values together
2.6 + 1.6 + 1.6 + 1.6 + 1.6 + 0.4 + 1.4 + 1.4 + 1.4 + 7.4 = 18
4. find the mean of the difference
18/10 = 1.8

Answer:
wdym like create a question about height that includes 'Grade 7' in it?
Step-by-step explanation:
I am guessing it is a rectangular room...
so a 5 x 3 1/4 meter room
The area of a rectangle is length * width
A = l * w
plug in the known
A = 5 * 3 1/4
A = 16.25, or 16 1/4
The area of Slater's?, or Slader's?, room is 16.25 meters^2
Hope this helps
