Find the margin of error if p = 65% and n = 500. round to four decimal places. 0.0427 0.0926 0.0009 0.0414

Option D is correct

Margin of error(to four decimal places) = 0.0414

Step-by-step explanation:

Given: p = 65% = 0.65 and n = 500

Error of margin (E) is given by:

For a confidence level of 95%,

Substitute the value of , p and n in the above formula to calculate error of margin (E) :

Simplify:

E = 0.0414082288551

Therefore, the margin of error(round to four decimal places) = 0.0414

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

14

step-by-step explanation:

14 x 3 = 42
