Answer:
A) The graph of f(x) = x2 is made narrower.
Step-by-step explanation:
The transformed graph has equation:
To see the transformations clearly, we need to rewrite the function in the vertex form:
Therefore, the graph of the original function is made narrow of the multplier, 3.
The correct answer is A
Answer:
no but if the box its very small then yes
3/35 = 0.0857 = 8.57% <== percent of the tip
35 + 3 = 38 <== total cost
Answer:
D. $126.79 + (-$75.10)
Step-by-step explanation:
Answer:
A1)
Stratified sampling: Here, sampling is performed on element within each stratum( the European store and the United States store. Therefore, The technique of randomly selecting 1,000 employees from a list of all employees at the United States stores and 600 employees form a list of all employees at the European stores is a stratified sampling.
A 11)
Cluster sampling :
It involves dividing total population into groups, which should be a representation of the total population and each identified cluster is treated as a sampling unit, by randomly selecting 8 stores from 800, we have chosen 8 clusters, and all samples in the 8 clusters being sampled signals a single stage cluster design.
B) Advantage : stratified sampling usually saves cost as it encourages a small subset of the population while also encougung representativeness.
Disadvantage : It requires that the experimenter has prior knowledge of the population before being able to group into stratums
