Answer:
Step-by-step: the two triangles are similar, their sides would match up and create the same ratio. However, as you can see
3
5
≠
4
12
≠
5
13
. Each side has a different ratio. Therefore, they don't necessarily have to be similar.
Ok, so lets convert all the percents into decimals to help us solve this problem
A 3.0%= 0.03
B 3.5%= 0.035
C 4.0%= 0.04
D 4.5%= 0.045
Now, we can multiply $200 by all the decimals we just converted to see which one will add up to $208
200*0.03= 6-------200+6=206 (this is not equal to 208 so it's not A)
200*0.035=7--------200+7= 207 (Still does not equal 208, so it's not B)
200*0.04= 8---------200+8=208 C is your answer
Answer:
c. Cluster sampling
Step-by-step explanation:
Taking into account that the exercise researcher is looking with limited resources to study a population that is divided, her best option is cluster sampling, which is a method applicable to this type of population, we could select in each group randomly her sample, the observational study is discarded because she does not have much availability of time or resources, nor would the stratified study be useful because she should select subgroups and create them to take samples and this would take more time and resources and sampling systematic is not adequate because it must have all the individuals and after having the list select the sample, but as we know, it is a process that will study the number of individuals so this option is not feasible.
5km = 5000 meters
450m+800m= 1250m
5000m-1250m= 3,750m
3 3/4 km
