Answer:
Point of estimate of the true Proportion 'p' = 0.1941
Step-by-step explanation:
<u>Explanation</u>:-
Given data a random sample of 340 people in Chicago showed that 66 listened to WJKT-1450, a radio station in South Chicago Heights.
Given sample size 'n'= 340
Point of estimate of the true Proportion P =
<u>Properties of Estimation</u>
An estimator is not expected to estimate the Population parameter without error.
An estimator should be close to the true value of un-known parameter.
Point of estimate of the true Proportion =
<u>Conclusion</u>:-
Point of estimate of the true Proportion = 0.1941

Answer:
B, C, F
Step-by-step explanation:
Given:
Subtract the second equation from the first equation:
Option B "The x coordinate of the solution is 9" is ture
Substitute it into the first equation:
Option F "The y coordinate of the solution is -8" is true.
Point (9,-8) is in the IV quadrant, so option C is true.
Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
A <u><em>circumscribed angle</em></u> is the angle made by two intersecting tangent lines to a circle
so
In this problem
BC and CD are tangents to the circle
BC=CD ----> by the Two Tangent Theorem
That means
Triangle ABC and Triangle ADC are congruent
so
Find the measure of angle BAC
In the right triangle ABC
substitute given value
Find the measure of angle BAD
Find the measure of minor arc BD
we know that
-----> by central angle
therefore
