Answer:
Hi
Step-by-step explanation:
Answer:
The correct option is C. The number of times a student guesses the answers to questions on a certain test.
Step-by-step explanation:
Discrete random variable is a type of variable that can only take a countable number of values. It can take values like 0, 1, 2, ....n.
The example of discrete random variable is the number of questions answered by a student in a test.
Option C is therefore correct because the number of times a student guesses the answers to questions on a certain test will take countable number of values like 0, 1, 2, 3...n. Where n is the number of guesses to the answers.
To find x, we have to use the pythagorean theorem.
a^2 + b^2 = c^2.
In our problem,
a = 3
b = ?
c = 6.5
(3)^2 + b^2 = (6.5)^2
Simplify the left and right side.
9 + b^2 = 42.25.
Subtract 9 from each side
b^2 = 33.25.
Take the square root of each side
b = 5.8.
Multiply 5.8 by two becuase 5.8 is the radius and we are looking for the diameter
x = 11.6
