Answer:
The answer is 0.8788
Step-by-step explanation:
<em>From question given, let us recall the following:</em>
<em>We know that Ƶα /2 * √p (1-p)/n</em>
<em>when we use n≤ 5000/10 =500</em>
<em> P = 0.75</em>
<em>The Margin of error = 0.03</em>
<em>Putting this values together we arrive at </em>
<em> Ƶα/2 = 0.03/√0.75 * 0.25/500 </em>
<em>= 1.549</em>
<em>Now,</em>
<em>Ф (1.549) = 0.9394</em>
<em>Therefore the confidence level becomes:</em>
<em> 1- (1-∝)/2 = 0.9394</em>
<em>∝ = 0.8788</em>
<em>The answer is 0.8788</em>

Answer:
Step-by-step explanation:
Always use your imaginary scissor:
Cut the above and below circle and the cylinder role it down-ways like a carpet and you will end up with two circles and a big rectangular.
Surface circle: 7 * 7 * 3,14 = 153.86
Surface carpet: 20 * circle exterior (or the length of the circle)= 20 * 2* 3.14 * 7
Results:
153, 86 * 2 (because we cut 2 circles from the cylinder) + 132,6 = 439.6
