I think the correct answer from the choices listed above is the third option. <span>If a statistic used to estimate a parameter is such that the mean of its sampling distribution is equal to the actual value of the parameter, then it is a biased estimator. Hope this answers the question.

There would be 30 adults because, if you were to take 3/10 and multiple both numbers until the denominator was 100 (10 X 10 = 100, 10 X 3 = 30). Resulting in your numerator to be 30. Therefore there were 30 adults.
Answer:
see explanation
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = 4(x + 2) ← is in point- slope form
with slope m = 4
Given a line with slope m then the slope of a line perpendicular to it is
= - = -
and (a, b) = ( - 2, 6), then
y - 6 = - (x - )- 2)), that is
y - 6 = - (x + 2)
Let A = arc length of circle
A = 2πr•(degree/360°)
A = 2π(12)(150°/360°)
A = 24π(150°/360°)
Calculate the right side to find A and you're done. Take it from here.
