Hi there!
Answer:
<u><em>x=403 and 403=x</em></u>
Step-by-step explanation:
Because a student says the answer is 347 is not the right answer. The final answer should be x=403 and 403=x.
375=x-28
Switch sides.
x-28=375
add by 28 both sides of an equation.
x-28+28=375+28
simplify.
x=403 and 403=x
403-28=375
28+375=403
Hope this helps!

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.
Subtract 5 (Cameron) and 2 (Karlee) from 49.
Why: Denise's age is basically the basic number. Karlee would be 2 years older, so subtract 2 from 49. You get 47. Cameron is 5 years older than Denise, so subtract 5. You get 42 and divide that by 3 since there are 3 people.
49 - 7 = 42
42 divide by 3 = 14
Check:
14 + 5 = 19
14 + 2 = 16
14 + 0 = 14
19 + 16 + 14 = 49
19 (Cameron) - 16 (Karlee) = 3 years older
16 (Karlee) - 14 (Denise) = 2 years older
19 (Cameron) - 14 (Denise) = 5 years older
