Homework on Calculating Percent Deviation

Show all work for math problems

1. Write the equation for percent deviation.

2. What does "accepted value" mean?

3. A student weighed a rock and found its mass to be 30g. When checked, he found out that the rock really has a mass of 25g. What is the percent deviation?

4. Biff measured the table.

See Biff rule.

Biff measured 150cm.

He was wrong- what a fool!

175cm is the right measurementation.

What is Biff's percent deviation?

5. Muffy is a Space Cadet.

She orbited a planet pulling on a tape measure.

She measured the planet to be 14,504km in circumference.

The actual circumference is 14,564km. (No, this one doesn't rhyme.)

What is Muffy's percent deviation?

6. Yor was a Viking. He had to cut wood for a boat. Each piece was to be 22 cubits long but Yor measured them to be 21 cubits. (He forgot to carry the 1).

What was his percent deviation?

7. A nerd measured a square (get it? nerd...square).

He calculated the area of the square to be 144mm2.

If each side is really 11mm, what is the percent deviation of the calculated area?
