62.5 is your answer in decimal
Answer:
w = 9/8
Step-by-step explanation:
4h+3=The Pay of Shea
3.5h +6= The pay of Kelly
4h+3=3.5h+6
-3 -3
4h=3.5h+3
-3.5h
.5h=3
*2 *2
h=?
Then stick "h" into one of the original equations and solve for someones pay to get "p"
3.5(h)+6=p OR 4(h)+3 =p
Answer: 4n^2
Step-by-step explanation: -3n^2 - (-7n^2) = -3n^2 + 7n^2= 4n^2. When adding and subtracting the exponents stay the same only the coefficients are subtracted or added
Answer: Cluster sampling
Step-by-step explanation:
Cluster sampling is a type of sampling method . With cluster sampling, the observer splits the population into separate groups which are called as called clusters. After dividing the whole populations into clusters he select a simple random sample of clusters from the population. The observer conducts his analysis on data from the sampled clusters.
From the given statement we can see that the automobile is doing his analysis by selecting three stores from each state (cluster) in the country and surveys all customers present in the store in a certain week.
Hence, he used cluster sampling .
