Troyanec [42]
Base = Height, Let them be x.

( x \times x) \div 2 = (x + x) + 6 \\ x ^{2} \div 2 = 2x + 6 \\ \frac{1}{2} x^{2} - 2x - 6 = 0
Solve quadratic equation:
x=6, x=-2(rejected because base and height is positive)

NikAS [45]

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>

marusya05 [52]

Let's compare!

Taylor ran 57 + 48 mins total. Sum would be 105 mins.

Mark ran 62 + 53 mins total. Sum would be 115 mins.

Clearly, the two sums are different when we compare them using subtraction.

115 - 105 = 10. Mark ran 10 mins longer than Taylor.
