Anson estimated he would need 17 hours to complete his science project. he actually needed 19 1 2 19 1 2 hours. what was his percent error? a. 12.8% b. 14.7% c. 87.2% d. 115%

The answer is B. 14.7%.

Step-by-step explanation:

Given:

Estimated time need to complete project .

Actually time needed =h.

Difference between the time = .

So, the percentage error is .

Therefore, the answer is B. 14.7%.

Option (A)

Anson percent error is 12.8%

Explanation:

Given the approximate value of completion = 17 hours

Exact value of completion = 19.5 hours

Absolute Error = Exact – Approximation  

Absolute Error = 19.5 – 17 = 2.5

% Error =

% Error =

Therefore, the percent error is 12.8%

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

the answer is y = 11.54

hope this : )
