Q+P =180 so (Q is 137) p=s so (s is 43) and q = r so (r is 137)
Answer:
a. is effective for use in school research.
Step-by-step explanation:
Cluster sampling is the sampling whereby we pick random few sample from the population to serve as the sample population called cluster. This cluster usually have uniform characteristics among them.
The main advantage of cluster sampling is that it is effective school research because of its cheapness and doesn't require much resources during the sampling process.
The other options are not correct because Cluster sampling have High sampling error and its biased sample.
Answer:
y = -2/3x - 1
Step-by-step explanation:
Let's solve for y.
y−5=−2/3(x+9)
Step 1: Add 5 to both sides.
y−5+5=−2/3x−6+5
y=−2/3x−1
Since all four terms don't have a common factor we will group them in pairs with common factors.
6uv - 3v^3 + 4u - 2v^2
6uv + 4u - 3v^3 - 2v^2
Take out 2u from the first two terms and -v^2 from the last two terms. The goal is to have a common factor once we take out the GCF's.
2u( 3v + 2) - v^2(3v + 2)
Now we have two terms:
[2u(3v+2)] + [-v^2(3v+2)]
These two terms have a GCF of (3v + 2). Take that out:
(3v + 2)(2u - v^2)
