Question

Theresa's estimate the height of a giraffe zoo is 18 feet in fact it is 16 feet what is Teresa's present portion solved the prompt should provide your answers and write your answers nearest 10th

Answer 1

To find Theresa's percent error in her estimate of the giraffe's height, we can use the following formula for percent error:

\[
\text{Percent Error} = \left( \frac{|\text{Estimated Value} - \text{Actual Value}|}{\text{Actual Value}} \right) \times 100
\]

In this case:

- Estimated Value = 18 feet
- Actual Value = 16 feet

Now, we can plug these values into the formula:

1. Calculate the absolute error:
\[
|\text{Estimated Value} - \text{Actual Value}| = |18 - 16| = 2
\]

2. Divide the absolute error by the actual value:
\[
\frac{2}{16} = 0.125
\]

3. Multiply by 100 to get percent error:
\[
0.125 \times 100 = 12.5
\]

Therefore, Theresa's percent error in her estimate of the giraffe's height is **12.5%**.

Answer 2

Can you simplify this down to 5th grade math

Answer 3

Sure! Here’s how to explain it simply:

To find out how far off Theresa's guess was, we can follow these steps:

1. **Find the Difference**: First, we need to see how much Theresa's guess (18 feet) was different from the real height (16 feet). We do that by subtracting the two numbers:
\[
18 - 16 = 2 \text{ feet}
\]
This means she was off by 2 feet.

2. **Compare to the Real Height**: Next, we want to see how big that difference (2 feet) is compared to the actual height (16 feet). We do that by dividing the difference by the actual height:
\[
\frac{2}{16} = 0.125
\]

3. **Turn It into a Percentage**: Finally, we want to change that number into a percentage. To do that, we multiply by 100:
\[
0.125 \times 100 = 12.5
\]

So, we say Theresa was **12.5% off** in her guess about the giraffe's height!

And that’s how you find out how far off her estimate was!
