Hey, amazing people can you help me? I will give 25 points and brainlist!

Bumek [7]

Answer: C, I think!

Step-by-step explanation: 3pi equals 9.4247. The square root of 100, is 10. So, that gives us 10/4. That simplified gives us 2.5.

For A, the square root of 36 is 6. 6 is in between 2.5 and pi, so that is not it.

For B, pi to the second power over 3 equals 3.2897, so that’s not it too!

For C, pi over 2 is 1.5708, so that is it, I’m pretty sure!

I’m only in 7th grade, so I’m sorry if it’s wrong!

Sorry if I made typos!

153 of the 258 high school students surveyed at a local school said they went outside more during school hours as elementary sch

Juli2301 [7.4K]

<u>Answer-</u>

<em>It </em><em>is reasonable</em><em> that the state education department claims the percentage for the entire state is 63%.</em>

<u>Solution-</u>

153 out of the 258 high school students surveyed at a local school said they went outside more during school hours as elementary school students than they do now as high school students.

Here,

x = 153,

n = 258,

Then,

$\text{sample proportion}=p=\dfrac{153}{258}=0.5930=59.30\%$

And,

$\text{Margin Error}=2\times \sqrt{\dfrac{p(1-p)}{n}}$

Putting the values,

$\text{ME}=2\times \sqrt{\dfrac{(0.5930)(1-0.5930)}{258}}\\\\=2\times \sqrt{\dfrac{(0.5930)(0.407)}{258}}\\\\=2\times \sqrt{\dfrac{0.2414}{208}}\\\\=2\times 0.0341\\\\=0.0682\\\\=6.82\%$

The interval would be,

$=(59.30-6.82,\ 59.30+6.82)\\\\=(52.48,\ 66.12)$

As population proportion p=63% lies in this interval, so it is reasonable.

Which of the following has a value of 84? <br> A. 512 <br> B. 4,096 <br> C. 32 <br> D. 83

andreev551 [17]

Answer is B. 4,096

I encountered this problem before. This is a trick question.
84 is not really the number 84. It is 8 raised to the 4th power.

So 8⁴ is equal to 4,096.

8 x 8 x 8 x 8 = 4,096

8 x 8 = 64
64 x 8 = 512
512 x 8 = 4,096
