Answer:
a. 385
b. 342
Step-by-step explanation:
To solve the problem we do the following:
The equation to calculate the sample size is:
a)
We have the following data:
Since no estimate of proportion is given, we will assume: p = q = 0.5
We know that For 95% confidence, z = 1.96
Width = 0.10
Hence, the margin of error would be:
0.10 / 2 = 0.05
E = 0.05
And so we can calculate sample size:
n = 385
b)
We have the following data for this point:
p = 2/3
q = 1 - p
q = 1 - 2/3
q = 1/3
And so we can calculate sample size:
n = 342
Given:
A figure of a circle.
To find:
The correct statement for the given figure.
Solution:
According to the tangent secant theorem, if two tangents or two secants are drawn to the circle from an exterior point, then the measure of angle between the tangents or secants is:
In the given figure, the exterior angle is 32 degrees, larger arc is QAI and smaller arc is QI.
Therefore, the correct option is C.
