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.
Answer: C. Would be correct

Answer:
The answer is below
Step-by-step explanation:
Trigonometric ratios shows the relationship between the sides of a right angled triangle and its angles. Some trigonometric ratios are:
sinθ = opposite / hypotenuse, cosθ = adjacent / hypotenuse; tanθ = opposite / adjacent.
In triangle PQR:
tanθ = QR / PQ
substituting gives:
3/4 = 9 / PQ
PQ = 9 * 4 / 3 = 12 cm
Applying Pythagoras in triangle PQR gives:
PR² = PQ² + QR²
PR² = 12² + 9²
PR² = 144 + 81 = 225
PR = 15 cm
Also in triangle PRS:
PS = (5/3)PR = (5/3)*15 = 25 cm
PS² = PR² + RS²
25² = 15² + RS²
625 = 225 + RS²
RS² = 400
RS = 20 cm
