Around 10,400 is a estimate or closer would be around 10,450
Answer: Systematic Random Sample
Step-by-step explanation:
Based on the information given, the method that would produce a random sample of 10 plants is the systematic random sample.
Systematic sampling is referred to as a probability sampling method whereby a random sample, that has a fixed periodic interval, will be chosen from the larger population. It should be noted that the fixed periodic interval, can be gotten by dividing the population by desired sample size.
In this case, since there are 5000 plants and there needs to ba a random sample of 10 plants, the fixed periodic interval will be: = 5000/10 = 500th plant. That means the 500th plant will be chosen.
To find the slope, you can either use the slope equation:
(y2-y1) / (x2-x1)
{I would recommend you remember this because you'll need to know this in the future}
or,
Just count. A slope is rise over run, so you see how far up the slope goes from one point to the other, (1), and then you see how far sideways the slope goes (2).
Going right, the slope is naturally declining downwards, so it's a negative.
The answer is B. -1/2.
