Step-by-step explanation:
The confidence interval for a population proportion is calculated using the formula;
In the above expression;
p represents the sample proportion calculated as, number of successes/sample size;
p = 120/319 = 0.3762
z represents the confidence coefficient associated with the given level of significance. In our case the confidence level required is 99%. The z-score associated with this level of significance is +/-2.576
n represents the sample size under evaluation, 319 college students.
Using the values obtained above, the 99% confidence interval for the true proportion of all college students who own a car is;
Given that the measure of ∠ADC = (7x + 2)° and arc AC = (8x - 8)°
We need to determine the measure of ∠ABC
<u>The value of x:</u>
The measure of ∠ADC can be determined using the formula,
Substituting the values, we get;
Thus, the value of x is 10.
<u>The measure of ∠ADC:</u>
Substituting the value x = 10 in the measure of ∠ADC = (7x + 2)°
We have;
Thus, the measure of ∠ADC is 72°
<u>The measure of ∠ABC:</u>
The measure of ∠ABC can be determined using the central angle theorem.
Thus, we have;
Thus, the measure of ∠ABC is 36°
Hence, Option A is the correct answer.
