Answer:
The correct statement is:
On average, the height of a garden gnome varies 3.2 inches from the mean of 6 inches.
Step-by-step explanation:
We are given a data of 11 gardens as:
2 9 1 23 3 7 10 2 10 9 7
Now on removing the outlier i.e. 23 (since it is the very large value as compared to other data points) the entries are as follows:
x |x-x'|
2 4
9 3
1 5
3 3
7 1
10 4
2 4
10 4
9 3
7 1
Now mean of the data is denoted by x' and is calculated as:
Hence, Mean(x')=6
Now,
∑ |x-x'|=32
Now mean of the absolute deviation is:
This means that , On average, the height of a garden gnome varies 3.2 inches from the mean of 6 inches.
Answer: 2???????
It's too short. Write at least 20 characters to explain it well.
-3x+2 < 8
-2 -2
-3 /-3x <6/-3
x >-2
So x>-2
Step-by-step explanation:
-1 is already a decimal.
For any fraction you can use: 2/3=x/100
After that, you get x=approx 0.66...
