Conditional relative frequency is the ratio of the the value of somthing with the total value for a set in data table. The value of the letter <em>a</em> is 0.1 and the value of the letter <em>b</em> is 0.85.
Given information
In the given table,
For the 16 year old weekend curfew is 0.9 before 10 pm and <em>a </em>after 10 pm in total 1.
For the 17 year old weekend curfew is <em>b</em> before 10 pm and 0.15<em> </em>after 10 pm in total 1.
There is total are with 0.88 before 10 pm and 0.12 after 10 pm in total of 1.
<h3>Conditional relative frequency-</h3>Conditional relative frequency is the ratio of the the value of somthing with the total value for a set in data table.
As for the relative conditional frequency the sum of the frequencies of each column should be equal to the one.
Hence for column two given in the table,
Solve for<em> a</em>,
Thus the value of the letter <em>a</em> is 0.1.
Hence for column three given in the table,
Solve for<em> a</em>,
Thus the value of the letter <em>b</em> is 0.85.

Answer:
Th correct option is D. 13
Therefore the value of x is 13.
Step-by-step explanation:
Given:
measure of an intercepted arc = 86°
Center Angle = 86°
measure of the inscribed angle creating the intercepted arc= (3x+4)°
Angle Inscribed in arc = (3x+4)°
To Find:
value of x = ?
Solution:
Inscribed Angle Theorem:
The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
Substituting the values we get
Therefore the value of x is 13.
