Question:

Daniel guesses that he scored a 95 on his science test. his actual score is 91. what is the percent error in daniel's guess? round to the nearest tenth of a percent.

Answers

1) Formula for the percent of error:

                               [estimated measure - real measure]
Percent of error = x 100
                                            real measure

2) Calculations:

                             [95 - 91]
Percent error =  x 100 = 4.4 %
                                 91

4.4%

4 percent pretty easy.

4.4%

Step-by-step explanation:

Because I took the test!

[tex]\boxed{\boxed{\%\ error=4.4\%}}[/tex]

Step-by-step explanation:

Daniel guessed that he would score 95 on his science test, but his actual score was 91.

We know that,

[tex]\%\ error=\dfrac{|\text{Expected value - True value}|}{\text{True value}}\times 100[/tex]

Here,

Expected value = 95

True value = 91

Putting the values,

[tex]\%\ error=\dfrac{|\text{95 - 91}|}{\text{91}}\times 100\\\\=\dfrac{|\text{4}|}{\text{91}}\times 100\\\\=\dfrac{4}{\text{91}}\times 100\\\\=4.39\approx 4.4\%[/tex]

Percentage error = 95-91 / 95 * 100 = 400/95 = 4.21%

After rounding-off to nearest tenth, it would be 4.20%

Error is | experimental or guessed answer - actual answer|
                                  actual answer

so | 95 - 91 |  =  4/91 = 0.043956 or 4.40%
          91

Percent error = (estimate - real number)/(real number) * 100

percent error = (95 - 91)/(91) * 100 = 4.3956%

4.4%

The answer is %0.8635 hope this helps

4.4%
