Answer:
x = 12
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the external part and the entire secant, that is
x² = 6(6 + 18) = 6 × 24 = 144 ( take the square root of both sides )
x = 
= 12

Answer:
Part A:
Type of Sampling: Convenience Sampling
It is a non-probability sampling technique. Though it is easy to carry out, it might be biased and can lead to under - representation or over - representation of particular groups within the sample. Since the sampling frame is not known and the sample is not chosen randomly, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied.
Part B.
The committee can implement this method as follows:
Step 1: Assign Serial Number to each and every student of the total of 2,500 student names.
Step 2:Using Random Number Generator App, obtain 400 Random numbers.
Step 3; The 400 numbers got in Step 2 form the desired Sample of 400 students out of 2,500 students.
