Irina predicted that she would sell 75 books, but she actually sold 95 books. Which expression would find the percent error? Use the table below to help answer the question.

Answers

There is no image of the table given.

Given:
approximate number = 75
exact number = 95

error = |approximate number - exact number| ÷ exact number
error = |(75-95)| / 95 = |20| / 95 = 0.21

percentage of error = 0.21 x 100% = 21%

Answer:

Given:

approximate number = 75

exact number = 95

error = |approximate number - exact number| ÷ exact number

error = |(75-95)| / 95 = |20| / 95 = 0.21

percentage of error = 0.21 x 100% = 21%

What is 1÷0?and is it possible

Answers

Instead of just assigning one willy nilly, we say that infinity isn't a number, and that 1/0 is undefined. When something is divided by 0, why is the answer undefined? The reason is related to the associated multiplication question. If you divide 6 by 3 the answer is 2 because 2 times 3 IS 6.
