Answer 2

Answer:

$\ \ 25$

Step-by-step explanation:

By definition, the absolute error is defined as:

$\epsilon = |x_a - x_e|$

Where:

$\epsilon$: is the error

$x_a$: is the approximate value

$x_e$: is the exact value

In this problem the approximate value was 100 and the exact value was 75. Then we substitute these values in the formula to find the error.

$\epsilon = |100 - 75|\\\epsilon = \ \ 25$
