Answer:
Yes, it is a quadratic equation.
Step-by-step explanation:
<em>Let's solve it to make it a quadratic equation:</em>
=> 
=> x²+1 = 5x²
=> 5x²-x²-1 = 0
=> 4x²-1 = 0
<em>Comparing it with the standard form of quadratic equation i.e. </em>
So, we get
a = 4 , b = 0 and c = -1
<u><em>So, yes. It is a quadratic equation and it is a pure quadratic equation since b is equal to 0.</em></u>
The type of sampling method proposed is a <u>convenience sampling</u> because it's a non-probability sampling method.
<h3>What is
convenience sampling?</h3>
Convenience sampling can be defined as a type of non-probability sampling method which involves surveying and selecting representatives that are easily accessible.
The CEO could implement the second sampling method as follows:
- Assign a serial number to each employees of the total 4,700 employee names.
- Use a random number generator software to obtain 600 random numbers.
- The 600 random numbers in Step 2 above forms the desired sample of 600 employees out of 4,700 employees at the company.
