Answer:
Systematic-sampling method is the right answer.
Step-by-step explanation:
A method of sampling in which the sample members are selected from a larger population according to a random starting spot but with a fixed, interval, is known as the systematic sampling method.
We can use the systematic sampling method in the given situation. Individual sample members are chosen at regular intervals from the sampling data. We use to chose the intervals to ensure enough sample size. The main advantage of using this method is that it is more convenient and it is easy to administer. The benefit of using this method will be that the number of aspen trees will be sampled from all across the national park.
Answer:
%
Step-by-step explanation:
Given: Jocelyn calculates that see will take 105 minutes to run 7 miles. She runs the distance in 84 minutes.
To find: Jillian’s percent error
Solution:
Actual time taken by Jocelyn to run 7 miles = 84 minutes
Approximate time taken by Jocelyn to run 7 miles = 105 minutes
Error = 
minutes
Percent error = error/(Actual time taken) × (100) = 
Answer:
-2

Answer:
$0.14
Step-by-step explanation:
To find slope given two points, there is a formula you can use: (y2-y1)/(x2-x1). Y2 stands for the second y coordinate and y1 stands for the first y coordinate. The same logic applies to the x's. Let's assume that (3, -2) is x1, y1 and (4,7) is x2, y2. Let's plug them into the formula.
(7-(-2))/(4-3).
7-(-2)=9 for total y value.
4-3=1 for the x value.
Now we divide them.
9/1=9. 9=m. M is the variable commonly used for slope. Hope this helped!
