Answer:
Simple random sampling
Step-by-step explanation:
Simple random sampling is a subdivision of a sample chosen from a population. Individuals are randomly chosen by chance and each individual possess the same characteristics as every other person in the population. It is a a surveying technique that is unbiased.
The idea of this sampling method is that every object has an equal chance of being chosen.
If the researcher evaluates 200 students out of the population and make sure the sample reflects the population, the sampling method used is simple random sampling.
Answer:
x=4
Step-by-step explanation:
Since it's a parallelogram, the angle BCE(79) = angle CED(79)
so... 79+63 = 142
now...
142+8x+6=180(sum of angles in a triangle)
148+8x=180
8x=32
x=4
Answer:
<em>Parallel slopes</em>: two lines that has the same slopes but have different y-intercept
<em>Perpendicular slope</em>: two lines that are negative reciprocals(common) of each other

Answers:</h3>
- Coefficient is -8
- Terms are 15 and -8x
- Constant is 15
Explanation:
The coefficient is the number just to the left of the variable. So that's why -8 is the coefficient for -8x. This is the variable term while 15 is the constant (it has no variable multiplied with it). The two terms are 15 and -8x since we can write 15-8x as 15+(-8x). Terms are separated by a plus sign.
