What is the value of q?

a.) 8.25
b.) 8.8
c.) 16.5
d.) 4.4

Measure of CD is also 16.5 units

Step-by-step explanation:

Given the figure in which distance from centre to chord is 4.4 units

we have to find the value of q

As radius from centre to the chord perpendicularly bisect the chord

⇒

From the figure, it can be seen that the distance from center to the chord  is equal that is in measure.

∴ Using the property that if the distance from the center to the chord is equal, then the chords are always in equal in measure.

As measure of AB is 16.5

⇒ Measure of CD is also 16.5 units

Hence, option (C) is correct.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
