Answer 1

wait do you have to round?

Answer 2

So you would multiply all, like so.;
\[259*32~percent=?\]
\[259*11~percent=?\]
\[259*12.36~percent=?\]
\[259*89~percent=?\]

Answer 3

tenths? idk-

Answer 4

We can obviously eliminate A.) and D.), they are too high.

Answer 5

your not even doing the percentage equation right

Answer 15

Omg, your screenshot doesn't even relate to the question...

Answer 16

okay you do you dude

Answer 17

The numbers are different but that's the correct method to answer the question

You won't always have answer choices

\(\text{Percent error}= \dfrac{|\text{predicted - actual}|}{\text{actual}} \times 100\text{%}\)

The predicted weight was 259
The actual weight was 291 pounds

Answer 18

If you look at your screenshot, look at the predicted vaule. Then, look at this question's predicted vaule.
