How are percent error and percent change similar
mihalych1998 [28]
Percent Change = New Value − Old Value|Old Value| × 100%

Example: There were 200 customers yesterday, and 240 today:

240 − 200|200|× 100% = 40200 × 100% = 20%

A 20% increase.

 

Percent Error = |Approximate Value − Exact Value||Exact Value| × 100%

Example: I thought 70 people would turn up to the concert, but in fact 80 did!

|70 − 80||80| × 100% = 1080 × 100% = 12.5%

I was in error by 12.5%

(Without using the absolute value, the error is −12.5%, meaning I under-estimated the value)

The difference between the two is that one states factual calculations and the other is a theoretical guess

Help please (will chose brainliest)
goldfiish [28.3K]

Answer:

LEts start with 10^1

If we have positive exponent then we add zeros

10^1= 10

10^2=100 (Put 2 zeros because exponent is 2)

10^3=1000 (Put 3 zeros because exponent is 3)

10^4=10000 (Put 4 zeros because exponent is 4)

10^5=100000 (Put 5 zeros because exponent is 5)

For negative exponent , we make a fraction . we put 1  at the top always and number as the bottom

10^{-1}=\frac{1}{10} (Put 1 zero at the bottom because exponent is -1)

10^{-2}=\frac{1}{100} (Put 2 zeros at the bottom because exponent is -2)

10^{-3}=\frac{1}{1000} (Put 3 zeros at the bottom because exponent is -3)
