Answer:
The sampling technique used here is Cluster Sampling.
Step-by-step explanation:
Since here Population is divided into different parts called grid and whole elements of some selected grid is taken as sample. So, Cluster Sampling is used here.
Further the different types of sampling we have are:
Simple Random Sampling is the sampling where samples are chosen randomly, where each unit has an equal chance of being selected in a sample.
If the population is divided into a different group called cluster and all elements of clusters are selected as a sample then it is Cluster Sampling.
In Convenience sampling, observers collect the sample as his\her convenience.
In Systematic Sampling sample is chosen by some criteria like he\she is taken every 10th unit as a sample from the population.
In Stratified Sampling population is divided into several groups such that within the group it is homogeneous and between the group it is heterogeneous. And now a selection of each stratum and unit has an equal chance of selection.
Answer:
za=24
Step-by-step explanation:
supplementary angles add up to equal 180
180=7x+x+30+6
step 1 combine like terms
180=8x+36
step 2 subtract 36 from each side
144=8x
step 3 divide each side by 8
x=18
now we just plug in 18 to x in x+6
18+6=24
Answer:
70
Step-by-step explanation:
Porque si haces 31-18=13
57-44=13 entonces están subiendo en 1e y luego haces 57+13=70
All you have to do is write your question and someone will answer. For example, instead of writing "I do not understand how I find answers on here" you would ask something like what is 9*5? Then 2 people will see your question and answer. There are no pre-recorded answers, everything happens live. Hope this helps!
