The correct answer is 2067
1. 35x + 0.15y
=3500x + 15y [multiplying the equation by 100]
= 700x + 3y [dividing the equation by 5]
2. Let x be an even integer
x + (x+2) + (x+2+2)
x+x+2+x+4
3x+6
3. 1/5*(r+7) - 9s
(r+7)/5 - 9s
4. x=cows
y= goats + sheep
x= (y+140)/2
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.

Answer:
8: 73.2 cm
10: 738 mm
Step-by-step explanation:
8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm
10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm
