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
Step-by-step explanation:
Answer:
(2x + 5) ( x + 5)
Step-by-step explanation:
2x² + 15 + 25
2x² + 10x + 5x + 25
2x( x + 5) + 5( x + 5)
(2x + 5) (x + 5)
Answer:
La F se considera separada ya que denota una calificación reprobatoria y no es necesario que vaya en orden alfabético. Da la casualidad de que "fallar" comienza con una letra que se salta una letra alfabéticamente en la escala. Dicho esto, se usó E en un momento.
Step-by-step explanation:
Given the marginal propensity to consume (MPC), the miltiplier is given by
Multiplier = 1 / (1 - MPC)
Given that the marginal propensity to consume is 0.8, the multiplier is given by
Multiplier = 1 / (1 - 0.8) = 1 / 0.2 = 5
Answer:
Parallel
Step-by-step explanation:
Parallel lines:
The parallel lines have same slope.
y = 2x + 3
Compare with slope y-intercept form of the line: y = mx +b
m is slope and b is the y-intercept.
slope of this line = 2
y = 2x
Slope = 2
These lines have same slope. So, they are parallel.
