Answer:
Thus, the expression to find the measure of θ in radians is θ = π÷3
Step-by-step explanation:
Given that the radius of the circle is 3 units.
The arc length is π.
The central angle is θ.
We need to determine the expression to find the measure of θ in radians.
Expression to find the measure of θ in radians:
The expression can be determined using the formula,
where S is the arc length, r is the radius and θ is the central angle in radians.
Substituting S = π and r = 3, we get;
Dividing both sides of the equation by 3, we get;
Answer:
A. We are 92% confident that the population mean height of college football players is between 63.2 and 65.9 inches.
Step-by-step explanation:
Confidence interval:
x% confidence
Of a sample
Between a and b.
Interpretation: We are x% sure(or there is a x% probability/chance) that the population mean is between a and b.
In this question:
92% confidence interval for the average height of football players is (63.2, 65.9).
Interpretation: We are 92% sure that the true average height of all college football players, that is, the population mean, is in this interval.
The correct answer is:
A. We are 92% confident that the population mean height of college football players is between 63.2 and 65.9 inches.
