Percentage error is calculated by
Percentage error = (estimate-real)/real*100%=(115-82.5)/82.5*100%=28.26%
An over-estimate gives a positive error percent, and an underestimate gives a negative error.
Also, dividing by the real value makes it possible to have more than 100% error.
For example, if real cost is $50, and estimated cost is $150, then error percent is (150-50)/50*100%=200%!
I guess this reads
You want to compute
By linearity of the definite integral,
Answer: x = 4
Step-by-step explanation:
We'll call the number "x."
"Twice the difference of a number and 3" means 2(x-3)
is equal to 2: =2
Put them together:
2(x-3) =2
2x - 6 = 2
2x = 8
x = 4
Check:
2(x-3)
Twice the difference of a number and 3 is equal to 2
2(4 - 3) = 2 ?
<h2>2(1) = 2 <u>
Yes</u></h2>
