Timmy estimated he would spend $9 at the candy store. He went a little over-budget and spent $12. What was the percent error?

kap26 [50]

<h2>Answer :</h2>

Error (e) = 12 - 9 = $ 3

assumed value (a) = $ 9

$\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}$

$\mathrm{ \% \: error =\dfrac{3}{9} ×100}$

$\mathrm{ \% \: error = \dfrac{1}{3} ×100}$

$\mathrm{ \% \: error = 33.33 \%}$

we have the function

$E=\sin \frac{\pi}{14}t$

Part a

For t=7

substitute in the given function

$\begin{gathered} E=\sin \frac{\pi}{14}7 \\ E=1 \end{gathered}$

For t=14

$\begin{gathered} E=\sin \frac{\pi}{14}14 \\ E=0 \end{gathered}$

For t=21

$\begin{gathered} E=\sin \frac{\pi}{14}21 \\ E=-1 \end{gathered}$

For t=28

$\begin{gathered} E=\sin \frac{\pi}{14}28 \\ E=0 \end{gathered}$

For t=35

$\begin{gathered} E=\sin \frac{\pi}{14}35 \\ E=1 \end{gathered}$

Observation: The values of E varies from -1 to 1, including the zero

Part B

Remember that

The Period goes from one peak to the next

Period=2pi/B

B=pi/14

Period=(2pi)/(pi/14)=2pi*14/pi=28

<h2>the period is 28 days</h2>
