Answer:
12.5
Step-by-step explanation:
89% of 14= 89/100 x 14
=12.46
Rounded to nearest tenth this is; 12.5
In this context *of* means times(x) and % means /100
<span>The Range Rule of Thumb says that the range is about four times the standard deviation. (i.e. two standard deviations to the left and two standard deviations to the right of the mean).
Given that the mean is 500 and the standard deviation is 50, then
The minimum and the maximum "usual" values are given by

Therefore, the minimun "usual" value is 400 while the maximum "usual" value is 600.

Answer:
The area of a rectangle is:
\sf A=lw
Plug in what we know:
\sf x^2-7x+10=l(x-5)
Factor the left side:
\sf (x-2)(x-5)=l(x-5)
Divide (x - 5) to both sides:
\sf l=\boxed{\sf x-2}
So the length is x - 2 meters.
