The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The Margin of error in this survey is 1%.

<h3>What is the margin of error?</h3>

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.

The random sample of 2500 sports fans, out of which 61% prefer basketball over soccer, therefore, we can write n=2500 and p=0.61. Thus, the margin of error can be written as,

MOE=\sqrt{\dfrac{\hat p(1-\hat p)}{n}} = \sqrt{\dfrac{0.61(1-0.61)}{2500}} = 0.00975 = 0.975\% \approx 1\%

Hence, the Margin of error in this survey is 1%.

(8v3-80v2+6)\(v-10)
Leto [7]

\frac{(8v^3-80v^2+6)}{v-10}

Use long division for dividing

(8v^3-80v^2+6) Here 'v' term is missing so we use 0vW

Divide (8v^3-80v^2+0v+6) by v-10 using long division

Step 1: Put 8v^2 at the top

step 2: multiply 8v^2 with v-10  and put it at the bottom

step 3: subtract it

We will get remainder 6

so quotient is  8v^2

Remainder is 6

9. If PQRS is a kite, find RQ. *<br><br> 17 ft.<br> 23 ft.<br> 30 ft.<br> 12 ft.
svetlana [45]

Answer:

17 ft

Step-by-step explanation:

The triangle on the bottom left is a right triangle.

a² + b² = c²

(8 ft)² + (15 ft)² = (RQ)²

64 ft² + 225 ft² = (RQ)²

(RQ)² = 289 ft²

RQ = 17 ft
