There is a difference because in the spring, there may be more days of rain, therefore that would increase the mean for the spring compared to the other days.
it is a relatively easy way to draw a sample while ensuring randomness is the answer.
Systematic sampling is a probabilistic sampling method in which a researcher selects members of a population at regular intervals. For example, select every 15 people from the list of populations. If the population is in random order, this can mimic the benefits of a simple random sample.
These are generally preferred by researchers because they are easy to implement and understand. The important assumption that the results represent the majority of the normal population ensures that the entire population is sampled equally. The process also provides a higher level of control for systematic sampling compared to other sampling methods. systematic sampling also has a lower risk factor because the data is unlikely to be contaminated.

L=3W+10 and P=2(L+W)=36
36=2(3W+10+W)
36=8W+20
8W=16
W=2 and since L=3W+10=16
W=2 and L=16
Answer:
25x25x25x25 Perfect square!
Step-by-step explanation:
Perfect square will always give you the most surface area.
So in this case...
100/4=25ft each side.
Thanks for letting me help!!
(x, y ) = (- 6, 3 )
Since both equations express y in terms of x, we can equate them
2x + 15 = - 
x + 1
( add x to both sides )
x + 15 = 1 ( subtract 15 from both sides )
x = - 14
( multiply both sides by 3 and divide by 7 )
x = ( 3 × - 14 )/7 = - 6
substitute x = - 6 into either of the 2 equations for y- coordinate )
y = ( 2 × - 6 ) + 15 = 3
solution : (x, y ) = ( - 6, 3 )
