Please help me answer this ASAP! The two-way table shows the number of ninth and tenth graders who prefer going to sporting even
Elis [28]
<h2>Answer</h2>

0.43

<h2>Explanation</h2>

Remember that RelativeFrecuency=\frac{Frecuency}{SumOfAllFrecuencies}

Since the problem is telling us "Among tenth graders", we must focus on the 10th graders row only. From the row, we can infer that the frequency is the number of 10th graders who prefer going to sporting events, so Frecuency=6. Now, the sum of all frequencies will be the sum of all the 10th graders, so SumOfAllFrecuencies=6+8=14. Let's replace the values:

RelativeFrecuency=\frac{Frecuency}{SumOfAllFrecuencies}

RelativeFrecuency=\frac{6}{14}

RelativeFrecuency=0.4285

And rounded to the nearest hundredth:

RelativeFrecuency=0.43

Find the cube roots of 27(cos 330Á + i sin 330Á). Please help c:
Mashcka [7]
Use formula
e^{ix}=\cos{x}+\sin{x}

\sqrt[3]{27(\cos{330^o}+i\sin{330^o})} &#10;\\\sqrt[3]{27e^{i330^o} }&#10;\\  \sqrt[3]{27}  \sqrt[3]{e^{i330^o}} &#10;\\ \sqrt[3]{3^3} \sqrt[3]{e^{i110^o\times 3}} &#10;\\ \sqrt[3]{3^3} \sqrt[3]{(e^{i110^o})^ 3}} &#10;\\ 3e^{i110^o}&#10;\\3(\cos{110^o}+i\sin{110^o})

Since 330^o=360^o+330^o=690^o&#10; and 330^o=2\times 360^o+330^o=1050^o there are two more solutions:
1. 3(\cos{230^o}+i\sin{230^o})
2. 3(\cos{350^o}+i\sin{350^o})
